[[Mainland Southeast Asia]] is entirely in the [[Northern Hemisphere]]. [[Timor-Leste]] and the southern portion of [[Indonesia]] are the parts of Southeast Asia that lie south of the [[equator]].

Southeast Asia is one of the most culturally diverse regions of the world. There are many different languages and ethnicities in the region. Historically, Southeast Asia was significantly influenced by [[Greater India|Indian]], [[East Asian cultural sphere|Chinese]], [[Islam in Southeast Asia|Muslim]], and [[European colonisation of Southeast Asia|colonial]] cultures, which became core components of the region's cultural and political institutions. Most modern Southeast Asian countries were colonised by European powers. European colonisation exploited natural resources and labour from the lands they conquered, and attempted to spread European institutions to the region.<ref>{{Cite web|url=https://cepr.org/voxeu/columns/economic-impact-colonialism|title=The economic impact of colonialism|website=CEPR|date=30 January 2017 }}</ref> Several Southeast Asian countries were also briefly occupied by the [[Empire of Japan|Japanese Empire]] during [[World War II]]. The [[aftermath of World War II]] saw most of the region decolonised.

==Definition==
[[File:Map of Southeast Asia.jpg|thumb|297x297px|States and regions of Southeast Asia]]

The region, together with part of South Asia, was well known by Europeans as the [[East Indies]] or simply the Indies until the 20th century. Chinese sources referred to the region as ''[[Nanyang (region)|Nanyang]]'' ("{{linktext|lang=zh|南洋}}"), which literally means the "Southern Ocean". The mainland section of Southeast Asia was referred to as [[Mainland Southeast Asia|Indochina]] by European geographers due to its location between China and the Indian subcontinent and its having cultural influences from both neighbouring regions. In the 20th century, however, the term became more restricted to territories of the former [[French Indochina]] (Cambodia, Laos, and Vietnam). The maritime section of Southeast Asia is also known as the [[Malay Archipelago]], a term derived from the European concept of a [[Malay race]].<ref name=Wallace>{{Cite book | last = Wallace | first = Alfred Russel | author-link = Alfred Russel Wallace | title = The Malay Archipelago | publisher = Macmillan | year = 1869 | location = London | page = 1 }}</ref> Another term for [[Maritime Southeast Asia]] is ''[[Malay Archipelago#Insulindia|Insulindia]]'' (Indian Islands), used to describe the region between Indochina and [[Australasia]].<ref>{{cite book|last1=Lach; Van Kley|first1=Donald F.; Edwin J|title=Asia in the Making of Europe, Volume III|date=1998|publisher=University of Chicago Press|location=Chicago|isbn=978-0-226-46768-9}}</ref>

The term "Southeast Asia" was first used in 1839 by American pastor Howard Malcolm in his book ''Travels in South-Eastern Asia''. Malcolm only included the Mainland section and excluded the Maritime section in his definition of Southeast Asia.<ref>{{cite book | date=1996 | first1=Joshua | last1=Eliot | title=Indonesia, Malaysia & Singapore Handbook | publisher=Trade & Trade & Travel Publications | location=New York City | first2=Jane | first3=Sebastian | last2=Bickersteth | last3=Ballard}}</ref> The term was officially used in the midst of [[World War II]] by the [[Allies of World War II|Allies]], through the formation of [[South East Asia Command]] (SEAC) in 1943.<ref>{{cite book|last1=Park; King|first1=Seung-Woo; Victor T.|title=The Historical Construction of Southeast Asian Studies: Korea and Beyond |date=2013 |publisher=Institute of Southeast Asian Studies |location=Singapore |isbn=978-981-4414-58-6}}</ref> SEAC popularised the use of the term "Southeast Asia", although what constituted Southeast Asia was not fixed; for example, SEAC excluded the [[Philippines]] and a large part of [[Indonesia]] while including [[Sri Lanka|Ceylon]]. However, by the late 1970s, a roughly standard usage of the term "Southeast Asia" and the territories it encompasses had emerged.<ref name="emmerson"/> Although from a cultural or linguistic perspective the definitions of "Southeast Asia" may vary, the most common definitions nowadays include the area represented by the countries (sovereign states and dependent territories) listed below.

Ten of the eleven states of Southeast Asia are members of the [[ASEAN|Association of Southeast Asian Nations]] (ASEAN), while [[Timor-Leste]] is an observer state. [[Papua New Guinea]] has stated that it might join ASEAN, and is currently an observer. Sovereignty issues exist over some [[South China Sea Islands|islands in the South China Sea]].

Timor-Leste and the eastern half of Indonesia (east of the [[Wallace Line]] in the region of [[Wallacea]]) are considered to be geographically associated with Oceania due to their distinctive faunal features. Geologically, the island of [[New Guinea]] and its surrounding islands are considered as parts of the [[Australia (continent)|Australian continent]], connected via the [[Sahul Shelf]]. Both [[Christmas Island]] and the [[Cocos (Keeling) Islands]] are located on the [[Australian plate]], south of the [[Sunda Trench]]. Even though they are geographically closer to Maritime Southeast Asia than [[mainland Australia]], these two [[states and territories of Australia|Australian external territories]] are not geologically associated with Asia as none of them is actually on the [[Sunda plate]]. The [[United Nations|UN]] [[United Nations Statistics Division|Statistics Division]]'s [[United Nations geoscheme|geoscheme]], which is a UN [[political geography]] tool created specifically for statistical purposes,<ref name=m49>[https://unstats.un.org/unsd/methodology/m49/ United Nations Statistics Division – Standard Country and Area Codes Classifications. The UNSD notes that "the assignment of countries or areas to specific groupings is for statistical convenience".]</ref> has classified both island territories as parts of [[Oceania]], under the [[United Nations geoscheme for Oceania#UNSD subregions|UNSD subregion "Australia and New Zealand"]] ([[Australasia]]).
Some definitions of Southeast Asia may include [[Taiwan]]. [[Taiwanese indigenous peoples|Taiwan]] has sometimes been included in Southeast Asia as well as East Asia but is not a member of [[ASEAN]].<ref>{{Cite web |title=A Nation Reborn? Taiwan's Belated Recognition of Its Southeast Asian Heritage |url=https://thediplomat.com/2018/09/a-nation-reborn-taiwans-belated-recognition-of-its-southeast-asian-heritage/ |access-date=1 July 2022 |website=thediplomat.com |language=en-US}}</ref> Likewise, a similar argument could be applied to some [[South China|southern parts of mainland China]], as well as [[Hong Kong]] and [[Macau]], may also considered as part of Southeast Asia as well as East Asia but are not members of [[ASEAN]].<ref name=":5" />

Ancient remains of hunter-gatherers in Maritime Southeast Asia, such as one Holocene hunter-gatherer from [[South Sulawesi]], had ancestry from both the Papuan-related and East Asian-related branches of the Eastern non-African lineage. The hunter-gatherer individual had approximately ~50% "Basal-East Asian" ancestry, and was positioned in between modern East Asians and Papuans of Oceania. The authors concluded that East Asian-related ancestry expanded from Mainland Southeast Asia into Maritime Southeast Asia much earlier than previously suggested, as early as 25,000BC, long before the expansion of [[Austroasiatic languages|Austroasiatic]] and [[Austronesian languages|Austronesian]] groups.<ref>{{Cite journal|last1=Carlhoff|first1=Selina|last2=Duli|first2=Akin|last3=Nägele|first3=Kathrin|last4=Nur|first4=Muhammad|last5=Skov|first5=Laurits|last6=Sumantri|first6=Iwan|last7=Oktaviana|first7=Adhi Agus|last8=Hakim|first8=Budianto|last9=Burhan|first9=Basran|last10=Syahdar|first10=Fardi Ali|last11=McGahan|first11=David P.|date=August 2021|title=Genome of a middle Holocene hunter-gatherer from Wallacea|journal=Nature|language=en|volume=596|issue=7873|pages=543–547|doi=10.1038/s41586-021-03823-6|issn=1476-4687|pmid=34433944|pmc=8387238|bibcode=2021Natur.596..543C|quote=The [[qpGraph]] analysis confirmed this branching pattern, with the Leang Panninge individual branching off from the Near Oceanian clade after the Denisovan gene flow, although with the most supported topology indicating around 50% of a basal East Asian component contributing to the Leang Panninge genome (Fig. 3c, Supplementary Figs. 7–11).|hdl-access=free|hdl=10072/407535}}</ref>

Distinctive [[East Asian people|Basal-East Asian]] (East-Eurasian) ancestry was recently found to have originated in Mainland Southeast Asia at ~50,000BC, and expanded through multiple migration waves southwards and northwards respectively. Geneflow of East Asian-related ancestry into [[Maritime Southeast Asia]] and [[Oceania]] could be estimated to ~25,000BC (possibly also earlier). The pre-Neolithic Papuan-related populations of Maritime Southeast Asia were largely replaced by the expansion of various East Asian-related populations, beginning about 50,000BC to 25,000BC years ago from Mainland Southeast Asia. The remainders, known as Negritos, form small minority groups in geographically isolated regions. Southeast Asia was dominated by East Asian-related ancestry already in 15,000BC, predating the expansion of [[Austroasiatic languages|Austroasiatic]] and [[Austronesian peoples]].<ref name="ncbi.nlm.nih.gov"/>

Studies presented by the [[Human Genome Organisation]] (HUGO) through genetic studies of the various peoples of Asia show empirically that there was a single migration event from Africa, whereby the early people travelled along the south coast of Asia, first entered the Malay Peninsula 50,000–90,000 years ago. The Orang Asli, in particular the [[Semang]] who show Negrito characteristics, are the direct descendants of these earliest settlers of Southeast Asia.

By the fifth century CE, trade networking between East and West was concentrated in the maritime route. Foreign traders were starting to use new routes such as [[Strait of Malacca|Malacca]] and [[Sunda Strait]] due to the development of maritime Southeast Asia. This change resulted in the decline of Funan, while new maritime powers such as [[Srivijaya]], [[Tarumanagara]], and [[Mataram Kingdom|Mataram]] emerged.

After the departure of the Mongols, Wijaya established the [[Majapahit Empire]] in eastern Java in 1293. Majapahit would soon grow into a regional power.

In the 11th century, a turbulent period occurred in the history of [[Maritime Southeast Asia]]. The Indian [[Chola]] navy crossed the ocean and attacked the [[Srivijaya]] kingdom of Sangrama Vijayatungavarman in Kadaram ([[Kedah Kingdom|Kedah]]); the capital of the powerful maritime kingdom was sacked and the king was taken captive. Along with Kadaram, Pannai in present-day [[Sumatra]] and Malaiyur and the Malayan peninsula were attacked too. Soon after that, the king of Kedah Phra Ong Mahawangsa became the first ruler to abandon the traditional [[Hindu]] faith, and converted to Islam with the [[Sultanate of Kedah]] established in 1136. [[Samudera Pasai]] converted to Islam in 1267, the King of Malacca [[Parameswara (sultan)|Parameswara]] married the princess of Pasai, and the son became the first sultan of Malacca. Soon, Malacca became the center of Islamic study and maritime trade, and other rulers followed suit. [[Indonesia]]n religious leader and Islamic scholar [[Hamka]] (1908–1981) wrote in 1961: "The development of Islam in Indonesia and [[Federation of Malaya|Malaya]] is intimately related to a Chinese Muslim, Admiral [[Zheng He]]."<ref>{{cite book|last=Wang Ma|first=Rosey|title=Chinese Muslims in Malaysia: History and Development|url=https://books.google.com/books?id=jK8ltwAACAAJ|year=2003|publisher=Center for Asia-Pacific Area Studies, Academia Sinica|access-date=1 April 2015|archive-date=4 September 2015|archive-url=https://web.archive.org/web/20150904021807/https://books.google.com/books?id=jK8ltwAACAAJ|url-status=live}}</ref>

There are several theories to the [[Islamization]] process in Southeast Asia. Another theory is trade. The expansion of trade among West Asia, India, and Southeast Asia helped the spread of the religion as Muslim traders from South Arabia ([[Hadhramaut]]) brought Islam to the region with their large volume of trade. Many settled in Indonesia, Singapore, and Malaysia. This is evident in the Arab-Indonesian, Arab-Singaporean, and Arab-Malay populations who were at one time very prominent in each of their countries. Finally, the ruling classes embraced Islam and that further aided the permeation of the religion throughout the region. The ruler of the region's most important port, [[Malacca Sultanate]], embraced Islam in the 15th century, heralding a period of accelerated conversion of Islam throughout the region as Islam provided a positive force among the ruling and trading classes. [[Gujarati Muslims]] played a pivotal role in establishing Islam in Southeast Asia.<ref name=toi>{{cite news|title=Gujarat helped establish Islam in SE Asia|url=https://timesofindia.indiatimes.com/city/ahmedabad/ampnbspGujarat-helped-establish-Islam-in-SE-Asia/articleshow/11262585.cms|newspaper=[[The Times of India]]|last=Prabhune|first=Tushar|location=[[Ahmedabad]]|date=27 December 2011|access-date=15 May 2018|archive-date=3 December 2019|archive-url=https://web.archive.org/web/20191203230825/https://timesofindia.indiatimes.com/city/ahmedabad/ampnbspGujarat-helped-establish-Islam-in-SE-Asia/articleshow/11262585.cms|url-status=live}}</ref>

===Contemporary history===
Most countries in the region maintain national autonomy. [[Democracy|Democratic forms of government]] are practised in most Southeast Asian countries and human rights is recognised but dependent on each nation state. Socialist or [[Communist state|communist countries]] in Southeast Asia include Vietnam and Laos. [[ASEAN]] provides a framework for the integration of commerce and regional responses to international concerns.

China has asserted broad claims over the [[South China Sea]], based on its [[nine-dash line]], and has [[Great Wall of Sand|built artificial islands]] in an attempt to bolster its claims. China also has asserted an [[exclusive economic zone]] based on the [[Spratly Islands]]. The [[Philippines]] challenged China in the [[Permanent Court of Arbitration]] in [[The Hague]] in 2013, and in ''[[Philippines v. China]]'' (2016), the Court ruled in favour of the Philippines and rejected China's claims.<ref>{{cite web|last=Liow|first=Joseph Chinyong|date=12 July 2016|title=What does the South China Sea ruling mean, and what's next?|url=https://www.brookings.edu/blog/order-from-chaos/2016/07/12/what-does-the-south-china-sea-ruling-mean-and-whats-next/|url-status=live|archive-url=https://web.archive.org/web/20180623141104/https://www.brookings.edu/blog/order-from-chaos/2016/07/12/what-does-the-south-china-sea-ruling-mean-and-whats-next/|archive-date=23 June 2018|access-date=6 January 2022|website=Brookings|language=en-US}}</ref><ref>Euan Graham, [https://www.cfr.org/councilofcouncils/global_memos/p38227 The Hague Tribunal's South China Sea Ruling: Empty Provocation or Slow-Burning Influence?] {{Webarchive|url=https://web.archive.org/web/20180310135823/https://www.cfr.org/councilofcouncils/global_memos/p38227 |date=10 March 2018 }}, Lowy Institute for International Policy (18 August 2016).</ref>

==Geography==
{{See also|Golden Triangle (Southeast Asia)|List of Southeast Asian mountains|Southeast Asian Massif}}

[[File:Southeast asia.svg|thumb|Relief map of Southeast Asia]]

Indonesia is the largest country in Southeast Asia and is also the largest archipelago in the world by size (according to the [[The World Factbook|CIA World Factbook]]). Geologically, the [[list of islands of Indonesia|Indonesian Archipelago]] is one of the most [[volcanology|volcanically]] active regions in the world. Geological [[Tectonic uplift|uplifts]] in the region have also produced some impressive mountains, culminating in [[Puncak Jaya]] in [[Papua (Indonesian province)|Papua]], Indonesia at {{convert|5030.|m|ft|abbr=off}}, on the island of [[New Guinea]]; it is the only place where ice glaciers can be found in Southeast Asia. The highest mountain in Southeast Asia is [[Hkakabo Razi]] at {{convert|5967.|m|ft|abbr=off}} and can be found in northern Burma sharing the same range of its parent peak, [[Mount Everest]].

The [[South China Sea]] is the major body of water within Southeast Asia. The Philippines, Vietnam, Malaysia, Brunei, Indonesia, and Singapore, have integral rivers that flow into the South China Sea.

[[Mayon Volcano]], despite being dangerously [[list of active volcanoes in the Philippines|active]], holds the record of the world's most perfect cone which is built from past and continuous [[types of volcanic eruptions|eruption]].<ref name="Davis">Davis, Lee (1992).

Geographically, Southeast Asia is bounded to the southeast by the [[Australia (continent)|Australian continent]], the boundary between these two regions is most often considered to run through [[Wallacea]].<!--

Geopolitically, the boundary lies between Papua New Guinea and the [[regions of Indonesia|Indonesian region]] of [[Western New Guinea]] (Papua and [[West Papua (province)|West Papua]]). Both countries share the island of [[New Guinea]].

Islands to the east of the Philippines make up the region of [[Micronesia]]. These islands are not biogeographically, geologically or historically linked to mainland Asia, and are considered part of Oceania by the [[United Nations]], ''[[The World Factbook]]'', and other organisations.<ref name="stats">{{cite web |url=https://unstats.un.org/unsd/methodology/m49/ |title=Methodology: Standard country or area codes for statistical use (M49) |website=[[United Nations Statistics Division]]}}</ref> The Oceania region is politically represented through the [[Pacific Islands Forum]], a governing body which, up until 2022, included Australia, [[New Zealand]] and all independent territories in [[Melanesia]], Micronesia, and [[Polynesia]].

===Climate===
[[File:Koppen-Geiger Map v2 Southeastern Asia 1991–2020.svg|thumb|Southeast Asia map of [[Köppen climate classification]]]]

Most of Southeast Asia have a [[tropical climate]] that is hot and humid all year round with plentiful rainfall. The majority of Southeast Asia has a wet and dry season caused by seasonal shifts in winds or [[monsoon]]s. The [[tropical rain belt]] causes additional rainfall during the monsoon season. The rainforest is the second largest on Earth (with the [[Amazon rainforest]] being the largest). Exceptions to the typical tropical climate and forest vegetation are:
# Places such as [[Northern Vietnam]] with a [[subtropical climate]] that is sometimes influenced by [[cold waves]] which move from the northeast and the [[Siberian High]]<ref>{{cite web |url=https://www.worlddata.info/asia/vietnam/climate.php |title=Vietnam Climate |website=WorldData.info |access-date=2023-11-24}}</ref>
## the northern part of Central Vietnam also is occasionally influenced by cold waves
# mountain areas in the northern region and the higher islands, where high altitudes lead to milder temperatures
# the [[Dry Zone (Myanmar)|“dry zone”]] of central Myanmar in the [[rain shadow]] of the [[Arakan Mountains]], where annual rainfall can be as low as {{convert|600|mm|in|0|disp=or}}, which under the hot temperatures that prevail is dry enough to qualify as [[semi-arid climate|semi-arid]]. 
# Southern areas in [[South Central Coast]] of Vietnam is marked with hot [[semi-arid climate]] due to weak monsoon activities and high temperature throughout the year. Annual rainfall of this region varies between {{convert|400|mm|in|0|disp=or}} to {{convert|800|mm|in|0|disp=or}}, with an 8-month dry season.

The vast majority of Southeast Asia falls within the warm, humid tropics, and its climate generally can be characterized as monsoonal. The animals of Southeast Asia are diverse; on the islands of [[Borneo]] and [[Sumatra]], the [[orangutan]], the [[Asian elephant]], the [[Malayan tapir]], the [[Sumatran rhinoceros]], and the [[Bornean clouded leopard]] can also be found. Six subspecies of the [[binturong]] or ''bearcat'' exist in the region, though the one endemic to the island of [[Palawan]] is now classed as vulnerable.

[[File:The Mayon Volcano.jpg|thumb|The [[Mayon|Mayon Volcano]], Philippines]]

Tigers of three different subspecies are found on the island of Sumatra (the [[Sumatran tiger]]), in peninsular Malaysia (the [[Malayan tiger]]), and in Indochina (the [[Indochinese tiger]]); all of which are endangered species.

The [[Komodo dragon]] is the largest living species of lizard and inhabits the islands of [[Komodo (island)|Komodo]], [[Rinca]], [[Flores]], and [[Gili Motang]] in Indonesia.

[[File:Pithecophaga jefferyi.jpg|thumb|upright|left|The [[Philippine eagle]]]]

The [[Philippine eagle]] is the [[national bird]] of the Philippines. It is considered by scientists as the largest eagle in the world,<ref>{{cite web | url=http://www.haribon.org.ph/index.php?view=article&id=223:the-largest-eagle-in-the-world&option=com_content&Itemid=119 | date=13 December 2012 | title=Climate Reality Watch Party 2016 | access-date=15 May 2018 | archive-date=20 August 2018 | archive-url=https://web.archive.org/web/20180820234906/http://www.haribon.org.ph/index.php?view=article&id=223%3Athe-largest-eagle-in-the-world&option=com_content&Itemid=119 | url-status=live }}</ref> and is endemic to the Philippines' forests.

The [[wild water buffalo]], and on various islands related dwarf species of ''[[Bubalus]]'' such as [[anoa]] were once widespread in Southeast Asia; nowadays the [[domestic Asian water buffalo]] is common across the region, but its remaining relatives are rare and endangered.

The [[mouse deer]], a small tusked deer as large as a toy dog or cat, mostly can be found on Sumatra, Borneo (Indonesia), and in Palawan (Philippines). The [[gaur]], a gigantic wild ox larger than even wild water buffalo, is found mainly in Indochina. There is very little scientific information available regarding Southeast Asian amphibians.<ref>{{Cite book|page=68|title=Southeast Asian Biodiversity in Crisis|author=Navjot S. Sodhi|author2=Barry W. Brook|publisher=[[Cambridge University Press]]|year=2006|isbn=978-0-521-83930-3}}</ref>

Birds such as the [[green peafowl]] and [[drongo]] live in this subregion as far east as Indonesia. The [[babirusa]], a four-tusked pig, can be found in Indonesia as well. The [[hornbill]] was prized for its beak and used in trade with China. The horn of the rhinoceros, not part of its skull, was prized in China as well.

The [[List of islands of Indonesia|Indonesian Archipelago]] is split by the [[Wallace Line]]. This line runs along what is now known to be a tectonic plate boundary, and separates Asian (Western) species from Australasian (Eastern) species. The islands between Java/Borneo and Papua form a mixed zone, where both types occur, known as Wallacea. As the pace of development accelerates and populations continue to expand in Southeast Asia, concern has increased regarding the impact of human activity on the region's environment. A significant portion of Southeast Asia, however, has not changed greatly and remains an unaltered home to wildlife. The nations of the region, with only a few exceptions, have become aware of the need to maintain forest cover not only to prevent [[soil erosion]] but to preserve the diversity of flora and fauna. Indonesia, for example, has created an extensive system of national parks and preserves for this purpose. Even so, such species as the [[Javan rhinoceros]] face extinction, with only a handful of the animals remaining in western Java.

[[File:Wallace's line.jpg|thumb|right|Wallace's hypothetical line divides Indonesian Archipelago into 2 types of fauna, Australasian and Southeast Asian fauna. The deepwater of the [[Lombok Strait]] between the islands of [[Bali]] and [[Lombok]] formed a water barrier even when lower sea levels linked the now-separated islands and landmasses on either side]]

The shallow waters of the [[Southeast Asian coral reefs]] have the highest levels of [[biodiversity]] for the world's marine ecosystems, where coral, fish, and molluscs abound. According to Conservation International, marine surveys suggest that the marine life diversity in the [[Raja Ampat]] (Indonesia) is the highest recorded on Earth. Diversity is considerably greater than any other area sampled in the Coral Triangle composed of Indonesia, the Philippines, and Papua New Guinea. The Coral Triangle is the heart of the world's coral reef biodiversity, the Verde Passage is dubbed by Conservation International as the world's "center of the center of marine shore fish biodiversity". The [[whale shark]], the world's largest species of fish and 6 species of [[sea turtle]]s can also be found in the [[South China Sea]] and the Pacific Ocean territories of the Philippines.

The trees and other plants of the region are tropical; in some countries where the mountains are tall enough, temperate-climate vegetation can be found. These rainforest areas are currently being logged-over, especially in Borneo.

While Southeast Asia is rich in flora and fauna, [[Deforestation in Southeast Asia|Southeast Asia is facing severe deforestation]] which causes habitat loss for various [[endangered species]] such as orangutan and the [[Sumatran tiger]]. Predictions have been made that more than 40% of the animal and [[Flora|plant species]] in Southeast Asia could be wiped out in the 21st century.<ref>{{cite web|last=Young|first=Emma|title=Biodiversity wipeout facing South East Asia|url=https://www.newscientist.com/article/dn3973-biodiversity-wipeout-facing-south-east-asia/|access-date=6 January 2022|website=New Scientist|language=en-US}}</ref> At the same time, [[haze]] has been a regular occurrence. The two worst regional hazes were in [[1997 Southeast Asian haze|1997]] and [[2006 Southeast Asian haze|2006]] in which multiple countries were covered with thick haze, mostly caused by "[[slash and burn]]" activities in Sumatra and Borneo. In reaction, several countries in Southeast Asia signed the [[ASEAN Agreement on Transboundary Haze Pollution]] to combat haze pollution.

The [[2013 Southeast Asian haze|2013 Southeast Asian Haze]] saw API levels reach a hazardous level in some countries. Muar experienced the highest [[Air pollution index|API]] level of 746 on 23 June 2013 at around 7 am.<ref>[[2013 Southeast Asian haze#Air Pollution Index readings]]</ref>

==Economy==
[[File:The port of Singapore.jpg|thumb|The [[Port of Singapore]] is the busiest [[transshipment]] and [[List of busiest container ports|container port]] in the world, and is an important transportation and shipping hub in Southeast Asia]]

Even prior to the penetration of European interests, Southeast Asia was a critical part of the world trading system. A wide range of commodities originated in the region, but especially important were spices such as pepper, ginger, cloves, and nutmeg. The spice trade initially was developed by Indian and Arab merchants, but it also brought Europeans to the region. First, [[Spain|Spaniards]] ([[Manila galleon]]) who sailed from the Americas and [[Kingdom of Portugal]], then the Dutch, and finally the British and French became involved in this enterprise in various countries. The penetration of European commercial interests gradually evolved into annexation of territories, as traders lobbied for an extension of control to protect and expand their activities. As a result, the Dutch moved into Indonesia, the British into [[Malay Peninsula|Malaya]] and parts of Borneo, the French into [[Indochina]], and the Spanish and the US into the Philippines. An economic effect of this imperialism was the shift in the production of commodities. For example, the rubber plantations of Malaysia, Java, Vietnam, and Cambodia, the tin mining of Malaya, the rice fields of the Mekong Delta in Vietnam, and the Irrawaddy River delta in Burma, were a response to the powerful market demands.<ref>{{cite book|author=Baten, Jörg |title=A History of the Global Economy.

The peoples of Southeast Asia are mainly divided into four major ethnolinguistic groups: the [[Austronesian peoples|Austronesian]], Austroasiatic (or Mon-Khmers), [[Tai peoples|Tai]] (part of the wider [[Kra-Dai]] family) and Tibeto-Burman (part of greater [[Sino-Tibetan]] language family) peoples. There is also a smaller but significant number of [[Hmong-Mien]], [[Han Chinese|Chinese]], [[Dravidian peoples|Dravidians]], [[Indo-Aryan peoples|Indo-Aryans]], Eurasians and Papuans, which also contributes to the diversity of peoples in the region.

The [[Orang Asli|Aslians]] and [[Negrito]]s were believed to be one of the earliest inhabitants in the region. They are genetically related to [[Indigenous people of New Guinea|Papuans]] in Eastern Indonesia, Timor-Leste and [[Australian Aborigines]]. In modern times, the [[Javanese people|Javanese]] are the largest ethnic group in Southeast Asia, with more than 100 million people, mostly concentrated in [[Java]], Indonesia. The second-largest ethnic group in Southeast Asia are the [[Vietnamese people|Vietnamese]] (Kinh people) with around 86 million people, mainly inhabiting Vietnam but also forming a significant minority in neighbouring Cambodia and Laos. The [[Thai people|Thais]] are the third largest with around 59 million people, forming the majority in Thailand.

[[Indonesia]] is politically and culturally dominated by the [[Javanese people|Javanese]] and [[Sundanese people|Sundanese]] ethnic groups (both native to Java), but the country also has hundreds of ethnic groups scattered throughout the archipelago, such as the [[Madurese people|Madurese]], [[Minangkabau people|Minangkabau]], [[Acehnese people|Acehnese]], [[Bugis]], [[Balinese people|Balinese]], [[Dayak people|Dayak]], [[Batak (Indonesia)|Batak]], [[Malay Indonesian|Malay]] and [[Ambonese people|Ambonese]] peoples.

In Malaysia, the country is demographically divided into [[Malaysian Malays|Malays]], who make up more than half of the country's population; the [[Malaysian Chinese|Chinese]], at around 22%; other [[Bumiputera (Malaysia)|Bumiputera]]s, at 12%; and [[Malaysian Indians|Indians]], at around 6%. In [[East Malaysia]], the [[Dayaks]] (mainly [[Iban people|Ibans]] and [[Bidayuh]]s) make up the majority in the state of [[Sarawak]], while the [[Kadazan-Dusun]]s make up the majority in [[Sabah]]. In [[Labuan]], the [[Bruneian Malay people|Bruneian Malays]] and [[Kedayan]]s are the largest groups. Overall, the [[Ethnic Malay|Malays]] are the majority in Malaysia and Brunei and form a significant minority in Indonesia, [[Thai Malays|Southern Thailand]], [[Burmese Malays|Myanmar]], and [[Malay Singaporean|Singapore]]. In Singapore, the demographics of the country is similar to that of its West Malaysian counterparts but instead of Malays, it is the [[Chinese Singaporean|Chinese]] that are the majority, while the Malays are the second largest group and [[Indian Singaporean|Indians]] third largest.

Within the Philippines, the country has no majority ethnic groups; but the four largest ethnolinguistic groups in the country are the [[Visayan people|Visayans]] (mainly [[Cebuano people|Cebuanos]], [[Waray people|Warays]] and [[Hiligaynon people|Hiligaynons]]), [[Tagalog people|Tagalogs]], [[Ilocano people|Ilocanos]] and [[Bicolano people|Bicolanos]]. Besides the major four, there are also the [[Moro people]]s of [[Mindanao]], consisting of the [[Tausug people|Tausug]], [[Maranao people|Maranao]], [[Yakan people|Yakan]] and [[Maguindanao people|Maguindanao]]. Other regional groups in the country are the [[Kapampangan people|Kapampangans]], [[Pangasinan people|Pangasinans]], [[Surigaonon people|Surigaonons]], [[Ifugao people|Ifugao]], [[Kalinga people|Kalinga]], [[Kamayo people|Kamayo]], [[Cuyonon people|Cuyonon]] and [[Ivatan people|Ivatan]].

In mainland Southeast Asia, the [[Bamar|Burmese]] accounts for more than two-thirds of the population in Myanmar, but the country also has several regional ethnic groups which mainly live in [[Administrative Divisions of Myanmar#States|states]] that are specifically formed for ethnic minorities. The major regional ethnic groups in Myanmar are the Tai-speaking [[Shan people]], [[Karen people]], [[Rakhine people]], [[Chin people]], [[Kayah people]] and Indo-Aryan-speaking [[Rohingya people]] living on the westernmost part of the country near the border with [[Bangladesh]]. In neighbouring Thailand, the Thais are the largest ethnic group in the country but is divided into several regional Tai groups such as Central Thais, [[Northern Thai people|Northern Thais or Lanna]], [[Southern Thai|Southern Thais or Pak Thai]], and Northeastern Thai or [[Isan people]] (which is ethnically more closely related to [[Lao people]] than to Central Thais), each have their own unique dialects, history and culture. Besides the Thais, Thailand is also home to more than 70 ethnolinguistic groups of which the largest being Patani Malays, [[Northern Khmers]], Karen, [[Hmong people|Hmongs]] and [[Thai Chinese|Chinese]].

Cambodia is one of the most homogeneous countries in the area, with [[Khmer people|Khmers]] forming more than 90% of the population but the country also has a large number of ethnic [[Cham people|Chams]], [[Vietnamese Cambodians|Vietnamese]] and various inland tribes categorised under the term [[Khmer Loeu]] (Hill Khmers).

Countries in Southeast Asia practice many different religions and the region is home to many world religions including Abrahamic, Indian, East Asian and Iranian religions. By population, [[Islam]] is the most practised faith with approximately 240 million adherents, or about 40% of the entire population, concentrated in [[Indonesia]], [[Brunei]], [[Malaysia]], [[Southern Thailand]] and in the [[Southern Philippines]]. Indonesia is the most populous Muslim-majority country in the world. Meanwhile, Islam is constitutionally the official religion in Malaysia and Brunei.<ref>{{Cite web |title=Malaysia - Religion {{!}} Britannica |url=https://www.britannica.com/place/Malaysia/Religion |access-date=2023-02-14 |website=www.britannica.com |language=en}}</ref><ref>{{Cite web |title=Home |url=https://www.mfa.gov.bn/oman-muscat/SitePages/bruneiintroduction.aspx#:~:text=Islam%20is%20the%20official%20religion,been%20since%20the%2014th%20century. |access-date=2023-02-14 |website=www.mfa.gov.bn}}</ref> The majority of the Muslim population is Sunni, but there are also significant Shia populations in Thailand and Indonesia. A minority are Sufi or Ahmadiyya Muslims.

There are approximately 190-205 million Buddhists in Southeast Asia, making it the second-largest religion in the region. Approximately 28 to 35% of the world's Buddhists reside in Southeast Asia. [[Buddhism]] is predominant in Vietnam, Thailand, Laos, Cambodia, Myanmar and Singapore, and adherents may come from Theravada or Mahayana schools. Ancestor worship and [[Confucianism]] are also widely practised in Vietnam and Singapore. Taoism and Chinese folk religions such as Mazuism are also widely practised by the overseas Chinese community in Malaysia, Singapore and Thailand. In certain cases, they may include Chinese or local deities in their worshipping practises such as Tua Pek Kong, Datuk Keramat and many more.

[[Christianity]] is predominant in the Philippines, eastern Indonesia, East Malaysia, and Timor-Leste. The Philippines has the largest Roman Catholic population in Asia.<ref>{{cite web|title=5 facts about Catholicism in the Philippines|url=https://www.pewresearch.org/fact-tank/2015/01/09/5-facts-about-catholicism-in-the-philippines/|access-date=5 July 2021|website=Pew Research Center|date=9 January 2015 |language=en-US|archive-date=25 June 2021|archive-url=https://web.archive.org/web/20210625213623/https://www.pewresearch.org/fact-tank/2015/01/09/5-facts-about-catholicism-in-the-philippines/|url-status=live}}</ref> Timor-Leste is also predominantly Roman Catholic due to a history of [[Indonesia]]n<ref name="Taylor, Jean Gelman 2003, p.381">{{cite book|last=Taylor|first=Jean Gelman|title=Indonesia: Peoples and Histories|url=https://archive.org/details/indonesia00jean|url-access=registration|publisher=Yale University Press|year=2003|page=[https://archive.org/details/indonesia00jean/page/381 381]|isbn=978-0-300-10518-6}}</ref> and Portuguese rule. In October 2019, the number of Christians, both Catholic and Protestant, in Southeast Asia reached 156 million, of which 97 million came from the [[Philippines]], 29 million from [[Indonesia]], 11 million from [[Vietnam]], and the rest from [[Malaysia]], [[Myanmar]], [[Timor-Leste]], [[Singapore]], [[Laos]], [[Cambodia]] and [[Brunei]]. In addition, Eastern Orthodox Christianity can also be found in the region. In addition, Judaism is practised in certain countries such as in the Philippines, Singapore and Indonesia due to the presence of Jewish diaspora. There is a small population of Parsis in Singapore who practise [[Zoroastrianism]], and [[Baháʼí Faith|Baháʼí]] is also practised by very small population in Malaysia, Vietnam, Singapore and Thailand.

No individual Southeast Asian country is religiously homogeneous. Some groups are protected ''de facto'' by their isolation from the rest of the world.<ref name=indigenous >{{cite news|first1=Euan|last1=McKirdy|first2=Sugam|last2=Pokharel|date=21 November 2018|title=North Sentinel Island tribespeople believed to have killed trespassing US 'missionary'|url=https://www.cnn.com/2018/11/21/asia/andaman-nicobar-us-missionary-killed-intl/index.html|access-date=6 January 2022|website=CNN|language=en|archive-date=12 November 2020|archive-url=https://web.archive.org/web/20201112071854/https://www.cnn.com/2018/11/21/asia/andaman-nicobar-us-missionary-killed-intl/index.html|url-status=live}}</ref> In the world's most populous Muslim nation, Indonesia, Hinduism is dominant on islands such as [[Bali]]. Christianity also predominates in the rest of the part of the Philippines, [[New Guinea]], [[Flores]] and [[Timor]]. Pockets of Hindu population can also be found around Southeast Asia in Singapore, Malaysia, etc. [[Garuda]], the [[Phoenix (mythology)|phoenix]] who is the mount (''vahanam'') of [[Vishnu]], is a national symbol in both Thailand and Indonesia; in the Philippines, gold images of Garuda have been found on [[Palawan]]; gold images of other Hindu gods and goddesses have also been found on [[Mindanao]]. [[Balinese Hinduism]] is somewhat different from Hinduism practised elsewhere, as [[animism]] and local culture is incorporated into it. Meanwhile, Hindu community in Malaysia and Singapore are mostly South Indian diaspora, hence the practices are closely related to the Indian Hinduism. Additionally, Sikhism is also practised by significant population especially in Malaysia and Singapore by North Indian diaspora specifically from Punjab region. Small population of the Indian diaspora in the region are Jains and can be found in Malaysia, Singapore, Thailand and Indonesia. Christians can also be found throughout Southeast Asia; they are in the majority in Timor-Leste and the Philippines, Asia's largest Christian nation. In addition, there are also older tribal religious practices in remote areas of [[Sarawak]] in East Malaysia, Highland Philippines, and Papua in eastern Indonesia. In Burma, Sakka ([[Indra]]) is revered as a ''[[nat (spirit)|Nat]]''. In Vietnam, Mahayana Buddhism is practised, which is influenced by native animism but with a strong emphasis on [[veneration of the dead|ancestor worship]]. Vietnamese folk religions are practised by majority of population in Vietnam. Caodaism, a monotheistic syncretic new religious movement, is also practised by less than one percent of the population in Vietnam. Due to the presence of Japanese diaspora in the region, the practice of  Shinto has growingly made appearance in certain countries such as in Thailand.

==Culture==
{{See also|Southeast Asian cinema|Southeast Asian Games|Southeast Asian music}}

[[File:Burmese puppetry.jpg|thumb|left|upright|Burmese puppet performance]]

The culture in Southeast Asia is diverse: on mainland Southeast Asia, the culture is a mix of Burmese, Cambodian, Laotian, Thai ([[Greater India|Indian]]) and Vietnamese ([[East Asian cultural sphere|Chinese]]) cultures. While in Indonesia, the Philippines, Singapore, and Malaysia the culture is a mix of indigenous [[Austronesian people|Austronesian]], Indian, Islamic, Western, and Chinese cultures. In addition, Brunei shows a strong influence from Arabia. Vietnam and Singapore show more Chinese influence<ref>{{cite web |url=http://unesdoc.unesco.org/images/0014/001478/147804eb.pdf |title=Introduction to Vietnamese culture |publisher=UNESCO |access-date=23 August 2021 |url-status=live |archive-date=17 June 2017 |archive-url=https://web.archive.org/web/20170617214630/http://unesdoc.unesco.org/images/0014/001478/147804eb.pdf }}</ref> in that Singapore, although being geographically a Southeast Asian nation, is home to a large Chinese majority and Vietnam was in [[East Asian cultural sphere|China's sphere of influence]] for much of its history. Indian influence in Singapore is most prominently evident through the Tamil migrants,<ref>{{cite magazine |url=http://www.microsite.nl.sg/PDFs/BiblioAsia/BIBA_0303Oct07a.pdf |title=Indian Migration into Malaya and Singapore During the British Period |first=Makeswary |last=Periasamy |magazine=biblioasia |issn=0219-8126 |volume=3 |issue=3 |date=October 2007 |pages=4–11 |access-date=22 July 2014 |url-status=dead |archive-url=https://web.archive.org/web/20121021102125/http://www.microsite.nl.sg/PDFs/BiblioAsia/BIBA_0303Oct07a.pdf |archive-date=21 October 2012 }}</ref> which influenced, to some extent, the [[cuisine of Singapore]]. Throughout Vietnam's history, it has had no direct influence from India – only through contact with the Thai, Khmer and Cham peoples. Moreover, Vietnam is also categorised under the [[East Asian cultural sphere]] along with China, Korea, and Japan due to a large amount of Chinese influence embedded in their culture and lifestyle.
[[File:Paddy field Viet Nam.jpg|thumb|[[Paddy field]] in Vietnam]]
[[Paddy field|Rice paddy]] agriculture has existed in Southeast Asia for millennia, ranging across the subregion. Some dramatic examples of these rice paddies populate the [[Banaue Rice Terraces]] in the mountains of Luzon in the [[Philippines]]. Maintenance of these paddies is very labour-intensive. The rice paddies are well-suited to the monsoon climate of the region.

[[Stilt house]]s can be found all over Southeast Asia, from Thailand and Vietnam to Borneo, to Luzon in the Philippines, to Papua New Guinea. The region has diverse metalworking, especially in Indonesia. This includes weaponry, such as the distinctive [[kris]], and musical instruments, such as the [[gamelan]].

===Influences===
The region's chief cultural influences have been from some combination of [[Islam]], [[Culture of India|India]], and [[Culture of China|China]]. Diverse cultural influence is pronounced in the Philippines, derived particularly from the period of Spanish and American rule, contact with Indian-influenced cultures, and the Chinese and Japanese trading era.

As a rule of thumb, the peoples who ate with their fingers were more likely influenced by the culture of India, for example, than the culture of China, where the peoples ate with [[chopstick]]s; tea, as a beverage, can be found across the region. The [[fish sauce]]s distinctive to the region tend to vary.

===Arts===
[[File:Royal Ballet Camboda Apsara Mera.jpg|thumb|The [[Royal Ballet of Cambodia]] (Paris, France 2010)]]The [[Southeast Asian arts|arts of Southeast Asia]] have an affinity with the arts of other areas. Dance in much of Southeast Asia includes movement of the hands as well as the feet, to express the dance's emotion and meaning of the story that the ballerina is going to tell the audience. Most of Southeast Asia introduced dance into their court; in particular, [[Khmer classical dance|Cambodian royal ballet]] represented them in the early seventh century before the [[Khmer Empire]], which was highly influenced by Indian Hinduism. The [[Apsara Dance]], famous for strong hand and feet movement, is a great example of Hindu symbolic dance.

Puppetry and shadow plays were also a favoured form of entertainment in past centuries, a famous one being the ''[[wayang]]'' from Indonesia. The arts and literature in some of Southeast Asia are quite influenced by Hinduism, which was brought to them centuries ago. Indonesia, despite large-scale conversion to Islam which opposes certain forms of art, has retained many forms of Hindu-influenced practices, culture, art, and literature. An example is the {{Lang|jv|[[wayang kulit]]}} (shadow puppet) and literature like the ''[[Ramayana]]''. The {{Lang|jv|wayang kulit}} show has been recognised by [[UNESCO]] on 7 November 2003 as a [[Masterpiece of Oral and Intangible Heritage of Humanity]].

It has been pointed out that Khmer and Indonesian classical arts were concerned with depicting the life of the gods, but to the Southeast Asian mind, the life of the gods was the life of the peoples themselves—joyous, earthy, yet divine. The [[Tai peoples|Tai]], coming late into Southeast Asia, brought with them some Chinese artistic traditions, but they soon shed them in favour of the Khmer and [[Mon people|Mon]] traditions, and the only indications of their earlier contact with [[culture of China|Chinese]] arts were in the style of their temples, especially the tapering roof, and in their [[lacquerware]].

====Music====
{{Main|Music of Southeast Asia}}

[[File:Angklung-arumba.jpg|thumb|right|The ''[[angklung]]'', designated as a [[Masterpieces of the Oral and Intangible Heritage of Humanity|Masterpiece of Oral and Intangible Heritage of Humanity]]]]

Traditional music in Southeast Asia is as varied as its many ethnic and cultural divisions. The main styles of traditional music include court music, folk music, music styles of smaller ethnic groups, and music influenced by genres outside the geographic region.

Of the court and folk genres, [[gong chime]] ensembles and orchestras make up the majority (the exception being lowland areas of Vietnam). ''[[Gamelan]]'' and ''[[angklung]]'' orchestras from ''[[Indonesia]]''; ''[[piphat]]'' and ''[[pinpeat]]'' ensembles of Thailand and Cambodia; and the ''[[kulintang]]'' ensembles of the southern Philippines, [[Borneo]], [[Sulawesi]] and [[Timor]] are the three main distinct styles of musical genres that have influenced other traditional musical styles in the region. String instruments are also popular in the region.

On 18 November 2010, UNESCO officially recognised the ''angklung'' as a ''Masterpiece of Oral and Intangible Heritage of Humanity'', and encouraged the Indonesian people and government to safeguard, transmit, promote performances and to encourage the craftsmanship of ''angklung'' making.

====Writing====
{{Main|Writing systems of Southeast Asia|Baybayin|Jawi script|S.E.A. Write Award|Thai alphabet}}

[[File:Thai manuscript Jim Thompson Museum IMG 7170.jpg|thumb|[[Thai script|Thai]] manuscript from before the 19th-century writing system|left]]

The history of Southeast Asia has led to a wealth of different authors, from both within and without writing about the region.

Some of the earliest writing systems of Southeast Asia stem from those of [[Culture of India|India]]. This is shown through [[Brahmic family|Brahmic]] forms of writing present in the region, such as the [[Balinese script]] shown on split palm leaves called ''lontar'' (see image to the left – magnify the image to see the writing on the flat side, and the decoration on the reverse side).
[[File:Pura Puseh 05153.jpg|thumb|Sign in [[Balinese script|Balinese]] and [[Latin script|Latin]] script at a [[Hindu]] temple in [[Bali]]]]
The antiquity of this form of writing extends before the invention of paper around the year 100 in China. Note each palm leaf section was only several lines, written longitudinally across the leaf, and bound by twine to the other sections. The outer portion was decorated. The alphabets of Southeast Asia tended to be [[abugida]]s, until the arrival of the Europeans, who used words that also ended in consonants, not just vowels. Other forms of official documents, which did not use paper, included Javanese copperplate scrolls. This material would have been more durable than paper in the tropical climate of Southeast Asia.

In Malaysia, Brunei, and Singapore, the Malay language is now generally written in the Latin script. The same phenomenon is present in Indonesian, although different spelling standards are utilised (e.g. 'Teksi' in Malay and 'Taksi' in Indonesian for the word 'Taxi').

The use of Chinese characters, in the past and present, is only evident in Vietnam and more recently, Singapore and Malaysia. The adoption of [[chữ Hán]] in Vietnam dates back to around 111 BC when it was occupied by the Chinese. A Vietnamese script called [[chữ Nôm]] used modified chữ Hán to express the Vietnamese language. Both chữ Hán and chữ Nôm were used up until the early 20th century.

[[Rapa Nui]] is an Austronesian language like those of Indonesian, Tagalog, and many other Southeast Asian languages. [[Rongorongo]] is presumed to be the script of Rapa Nui and if proven so, would place it as one of very few [[inventions of writing]] in human history.<ref>{{cite book | title=Writing and Script: A Very Short Introduction | author=Robinson, Andrew | publisher=Oxford University Press | year=2009 | section=The death of RongoRongo | url=https://books.google.com/books?id=zcXH52jICOEC| isbn=9780191579165 }}</ref>

====Sports====
{{See also|SEA Games}}
[[Association football]] is the most popular sport in the region, with the [[ASEAN Football Federation]], the region's primary regulatory body, formed on 31 January 1984, in [[Jakarta]], Indonesia. The [[AFF Championship]] is the largest football competition in the region since its inaugural in [[1996 AFF Championship|1996]], with [[Thailand national football team|Thailand]] holding the most titles in the competition with seven titles. The reigning winner is Thailand, who defeated [[Vietnam national football team|Vietnam]] in the [[2022 AFF Championship|2022]] final. Thailand has had the most numerous appearances in the [[AFC Asian Cup]] with 7 while the highest-ranked result in the Asian Cup for a Southeast Asian team is second place in the [[1968 AFC Asian Cup|1968]] by [[Myanmar national football team|Myanmar]] in [[Iran]]. [[Dutch East Indies national football team results|Indonesia]] is the only Southeast Asian team to have played in the [[1938 FIFA World Cup]] as the [[Dutch East Indies national football team results|Dutch East Indies]].

ASEAN has also committed to preserving [[traditional sports and games]] (TSG) in the region.<ref>{{Cite web |title=Promoting and Safeguarding Traditional Sports and Games in ASEAN: Challenges, Opportunities, and Strategies |url=https://asean.org/book/promoting-and-safeguarding-traditional-sports-and-games-in-asean-challenges-opportunities-and-strategies/ |access-date=2024-11-18 |website=asean.org}}</ref>
