There is confusion over the exact process of derivation from these Ancient Greek verbs to the concept of diaspora. Many cite Thucydides (5th century BC) as the first to use the word.Template:SfnTemplate:SfnTemplate:Sfn However, sociologist Stéphane Dufoix remarks "not only is the noun diaspora quite absent from the Greek original [Thucydides' Peloponnesian War, II, 27)], but the original does not include the verb diaspeírô either. The verb used is the verb speírô (seed) conjugated in the passive aorist."Template:Sfn The passage in Thucydides reads:
Template:Lang, translated to mean 'Those of the Aeginetans who did not settle here were scattered over the rest of Hellas.'<ref>Template:Cite web</ref>
Dufoix further notes, "Of all the occurrences of diaspora in the Thesaurus Linguae Graecae (TLG), which draws upon almost the entire written corpus in the Greek language . . . none refer to colonisation."Template:Sfn Dufoix surmises that the confusion may stem from a comment by Jewish historian Simon Dubnow, who wrote an entry on diaspora for the influential Encyclopaedia of the Social Sciences.Template:Sfn His entry, published in 1931, includes the following remark: "In a sense Magna Graecia constituted a Greek diaspora in the ancient Roman Empire."Template:SfnTemplate:Efn "Magna Graecia" refers to ancient Greek colonies established along the Italian coast, which lost their independence following the Second Punic War and their integration into the Roman Empire.
The first recorded use of the word "diaspora" is found in the Septuagint, first in:
Psalms 146(147).2, in the phrase Template:Lang, Template:Lang, translated to mean 'The Lord doth build up Jerusalem: he gathereth together the outcasts of Israel'.
When the Bible was translated into Greek, the word diaspora was applied in reference to the Kingdom of Samaria which was exiled from Israel by the Assyrians between 740 and 722 BC,<ref>Assyrian captivity of Israel</ref> as well as Jews, Benjaminites, and Levites who were exiled from the Kingdom of Judah by the Babylonians in 587 BC, and Jews who were exiled from Roman Judea by the Roman Empire in 70 AD.<ref>Kantor, pp. 53, 105–106.</ref> It subsequently came to be used in reference to the historical movements and settlement patterns of the Jews.<ref>p. 1, Barclay</ref> In English, capitalized, and without modifiers, the term can refer specifically to the Jewish diaspora.<ref>Template:Cite web</ref> The wider application of diaspora evolved from the Assyrian two-way mass deportation policy of conquered populations to deny future territorial claims on their part.<ref>Galil & Weinfeld, pp. 96–97.</ref>
This scattering abrode of the Iewes, as it were an heauenly sowing, fell out after their returne from the captiuitie of Babylon. Wherevpon both Acts. 2. and also 1. Pet. 1. and 1. Iam. ver. 1. [sic] they are called Diaspora, that is, a scattering or sowing abrode.<ref>Template:Cite book</ref>
However, the current entry on "diaspora" in the Oxford English Dictionary Online dates the first recorded use a century later to 1694, in a work on ordination by the Welsh theologian James Owen. Owen wanted to prove that there is no difference in the Bible between Presbyters and Bishops; he cited the example of the Jews in exile:
The Presbyters of the Jewish Diaspora, to whom St. Peter wrote, are requir'd ποιμαίνειν ϗ̀ ἐπισκοπείν, to feed or rule the Flock, and to perform the office and work of Bishops among them.<ref>Template:Cite book Many today believe that the audience of the First Epistle of Peter to which Owen refers was in fact Christians of non-Jewish origin, but the consensus in Owen's time was that the letter was directed to ethnic Jews. See for example Template:Cite book</ref>
The OED records a usage of "diaspora" in 1876, which refers to "extensive diaspora work (as it is termed) of evangelizing among the National Protestant Churches on the continent".<ref>Template:Cite web</ref>
The term became more widely assimilated into English by the mid 1950s, with long-term expatriates in significant numbers from other particular countries or regions also being referred to as a diaspora.<ref>Template:Cite encyclopedia</ref> An academic field, diaspora studies, has become established relating to this sense of the word.
William Safran in an article published in 1991,Template:Sfn set out six rules to distinguish diasporas from migrant communities. These included criteria that the group maintains a myth or collective memory of their homeland; they regard their ancestral homeland as their true home, to which they will eventually return; being committed to the restoration or maintenance of that homeland, and they relate "personally or vicariously" to the homeland to a point where it shapes their identity.Template:SfnTemplate:SfnTemplate:Sfn Safran's definitions were influenced by the idea of the Jewish diaspora.Template:Sfn Safran also included a criterion of having been forced into exile by political or economic factors, followed by a long period of settlement in the new host culture.Template:Sfn In 1997, Robin Cohen argued that a diasporic group could leave its homeland voluntarily, and assimilate deeply into host cultures.<ref>Template:Cite book</ref>
Rogers Brubaker (2005) more inclusively applied three basic definitional criteria: First, geographic dispersion (voluntary or forced) of a people; second, "the orientation to a real or imagined 'homeland' as an authoritative source of value, identity and loyalty"; and third, maintenance of a social boundary corresponding to the conservation of a distinctive diasporic identity which differs from the host culture.Template:Sfn Brubaker also noted that the use of the term diaspora has been widening. He suggests that one element of this expansion in use "involves the application of the term diaspora to an ever-broadening set of cases: essentially to any and every nameable population category that is to some extent dispersed in space".Template:Sfn Brubaker used the WorldCat database to show that 17 out of the 18 books on diaspora published between 1900 and 1910 were on the Jewish diaspora. The majority of works in the 1960s were also about the Jewish diaspora, but in 2002 only two out of 20 books sampled (out of a total of 253) were about the Jewish case, with a total of eight different diasporas covered.Template:Sfn
Brubaker outlined the original use of the term diaspora as follows:Template:Sfn
Some observers have labeled evacuation from New Orleans and the Gulf Coast in the wake of Hurricane Katrina the New Orleans diaspora, since a significant number of evacuees have not been able to return, yet maintain aspirations to do so.<ref>Template:Cite news</ref><ref>Template:Cite news</ref> Agnieszka Weinar (2010) notes the widening use of the term, arguing that recently, "a growing body of literature succeeded in reformulating the definition, framing diaspora as almost any population on the move and no longer referring to the specific context of their existence".Template:Sfn It has even been noted that as charismatic Christianity becomes increasingly globalized, many Christians conceive of themselves as a diaspora, and form a bond that mimics salient features of some ethnic diasporas.<ref>Template:Cite web</ref>
Professional communities of individuals no longer in their homeland can also be considered diaspora. For example, science diasporas are communities of scientists who conduct their research away from their homeland<ref>Template:Cite journal</ref> and trading diasporas are communities of merchant aliens. In an article published in 1996, Khachig TölölyanTemplate:Sfn argues that the media have used the term corporate diaspora in a rather arbitrary and inaccurate fashion, for example as applied to "mid-level, mid-career executives who have been forced to find new places at a time of corporate upheaval" (10) The use of corporate diaspora reflects the increasing popularity of the diaspora notion to describe a wide range of phenomena related to contemporary migration, displacement and transnational mobility. While corporate diaspora seems to avoid or contradict connotations of violence, coercion, and unnatural uprooting historically associated with the notion of diaspora, its scholarly use may heuristically describe the ways in which corporations function alongside diasporas. In this way, corporate diaspora might foreground the racial histories of diasporic formations without losing sight of the cultural logic of late capitalism in which corporations orchestrate the transnational circulation of people, images, ideologies and capital.
In contemporary times, scholars have classified the different kinds of diasporas based on their causes, such as colonialism, trade/labour migrations, or the social coherence which exists within the diaspora communities and their ties to the ancestral lands. With greater migration flows through the world in modern times, the concept of a secondary diaspora (a new diaspora branching out of a previous diaspora) or sub-diaspora groupings has started being studied.<ref>Mission in “the Present Time”: What about the People in Diaspora? Michael A. Rynkiewich</ref><ref>Template:Cite journal</ref> Some diaspora communities maintain strong cultural and political ties to their homelands. Other qualities that may be typical of many diasporas are thoughts of return to the ancestral lands, maintaining any form of ties with the region of origin as well as relationships with other communities in the diaspora, and lack of full integration into the new host countries. Diasporas often maintain ties to the country of their historical affiliation and usually influence their current host country's policies towards their homeland. "Diaspora management" is a term that Harris Mylonas has "re-conceptualized to describe both the policies that states follow in order to build links with their diaspora abroad and the policies designed to help with the incorporation and integration of diasporic communities when they 'return' home".<ref>Template:Cite book</ref>
The diaspora of Africans during the Atlantic slave trade is one of the most notorious modern diasporas. 10.7 million people from West Africa survived transportation to arrive in the Americas as slaves starting in the late 16th century CE and continuing into the 19th.Template:Cn Outside of the Atlantic slave trade, however, African diasporic communities have existed for millennia. While some communities were slave-based, other groups emigrated for various reasons.
Beginning as early as the 2nd century AD, the kingdom of Aksum (modern-day Ethiopia) created colonies on the Arabian Peninsula. During the 4th century, Aksum formally adopted Christianity as a state religion, becoming the first to do so along with Armenia. In the 6th century, Kaleb of Axum invaded Himyar (modern-day Yemen) to aid and defend Christians under religious persecution. During these campaigns, several groups of soldiers chose not to return to Aksum. These groups are estimated to have ranged in size from the 600s to mid 3000s.<ref>Template:Cite book</ref>
Previously, migrant Africans with national African passports could only enter thirteen African countries without advanced visas. In pursuing a unified future, the African Union (AU) launched an African Union Passport in July 2016, allowing people with a passport from one of the 55 member states of the AU to move freely between these countries under this visa free passport and encourage migrants with national African passports to return to Africa.<ref>Template:Cite web</ref><ref>Template:Cite news</ref><ref>Template:Cite web</ref>
The largest Asian diaspora in the world is the Indian diaspora. The overseas Indian community, estimated to number over 17.5 million, is spread across many regions of the world, on every continent.

Chinese emigration (also known as the Chinese Diaspora; see also Overseas Chinese)<ref>Template:Cite book</ref> first occurred thousands of years ago. The mass emigration that occurred from the 19th century to 1949 was caused mainly by wars and starvation in mainland China, as well as political corruption. Most migrants were illiterate or poorly educated peasants, called by the now-recognized racial slur coolies (Template:Zh), who migrated to developing countries in need of labor, such as the Americas, Australia, South Africa, Southeast Asia, Malaya and other places.
The Pakistani diaspora is the third largest diaspora in Asia with approximately 10 million Pakistanis living abroad mostly in Middle East, North America and Europe.<ref>Template:Cite web</ref>
At least three waves of Nepalese diaspora can be identified.<ref>Template:Cite book</ref> The earliest wave dates back hundreds of years as early marriage and high birthrates propelled Hindu settlement eastward across Nepal, then into Sikkim and Bhutan. A backlash developed in the 1980s as Bhutan's political elites realized that Bhutanese Buddhists were at risk of becoming a minority in their own country. At least 60,000 ethnic Nepalese from Bhutan have been resettled in the United States.<ref>Template:Cite news</ref> A second wave was driven by British recruitment of mercenary soldiers beginning around 1815 and resettlement after retirement in the British Isles and Southeast Asia. The third wave began in the 1970s as land shortages intensified and the pool of educated labor greatly exceeded job openings in Nepal. Job-related emigration created Nepalese enclaves in India, the wealthier countries of the Middle East, Europe, and North America. Current estimates of the number of Nepalese living outside Nepal range well up into the millions.
In Siam, regional power struggles among several kingdoms in the region led to a large diaspora of ethnic Lao between the 1700s–1800s by Siamese rulers to settle large areas of the Siamese kingdom's northeast region, where Lao ethnicity is still a major factor in 2012. During this period, Siam decimated the Lao capital, capturing, torturing, and killing the Lao king Anuwongse, who led the Lao rebellion in the 19th century.
Alexander the Great's conquest of the Achaemenid Empire marked the beginning of the Hellenistic period, characterized by a new wave of Greek colonization in Asia and Africa, with Greek ruling classes established in Egypt, southwest Asia and northwest India.<ref>Template:Cite web</ref> Subsequent waves of colonization and migration during the Middle Ages added to the older settlements or created new ones, thus replenishing the Greek diaspora and making it one of the most long-standing and widespread in the world. The Romans also established numerous colonies and settlements outside of Rome and throughout the Roman empire.
The Migration Period relocations, which included several phases, are just one set of many in history. The first phase Migration-Period displacement (between 300 and 500 AD) included relocation of the Goths (Ostrogoths and Visigoths), Vandals, Franks, various other Germanic peoples (Burgundians, Lombards, Angles, Saxons, Jutes, Suebi and Alemanni), Alans and numerous Slavic tribes. The second phase, between 500 and 900 AD, saw Slavic, Turkic, and other tribes on the move, resettling in Eastern Europe and gradually leaving it predominantly Slavic, and affecting Anatolia and the Caucasus as the first Turkic tribes (Avars, Huns, Khazars, Pechenegs), as well as Bulgars, and possibly Magyars arrived. The last phase of the migrations saw the coming of the Hungarian Magyars. The Viking expansion out of Scandinavia into southern and eastern Europe, Iceland, the British Isles and Greenland. The recent application of the word "diaspora" to the Viking lexicon highlights their cultural profile distinct from their predatory reputation in the regions they settled, especially in the North Atlantic.<ref>Jesch, J. A Viking Diaspora, London, Routledge.</ref> The more positive connotations associated with the social science term help to view the movement of the Scandinavian peoples in the Viking Age in a new way.<ref>Adrams, L. "Diaspora and Identity in the Viking Age", Early Medieval Europe, vol. 20(1), pp. 17–38.</ref>
Such colonizing migrations cannot be considered indefinitely as diasporas; over very long periods, eventually, the migrants assimilate into the settled area so completely that it becomes their new mental homeland. Thus the modern Magyars of Hungary do not feel that they belong in the Western Siberia that the Hungarian Magyars left 12 centuries ago; and the English descendants of the Angles, Saxons and Jutes do not yearn to reoccupy the plains of Northwest Germany.
In 1492 a Spanish-financed expedition headed by Christopher Columbus arrived in the Americas, after which European exploration and colonization rapidly expanded. Historian James Axtell estimates that 240,000 people left Europe for the Americas in the 16th century.<ref>Template:Cite journal</ref> Emigration continued. In the 19th century alone over 50 million Europeans migrated to North and South America.<ref>Template:Cite book</ref> Other Europeans moved to Siberia, Africa, and Australasia. The properly Spanish emigrants were mainly from several parts of Spain, but not only the impoverished ones (i.e., Basques in Chile), and the destination varied also along the time. As an example, the Galicians moved first to the American colonies during the XVII-XX (mainly but not only Mexico, Cuba, Argentine and Venezuela, as many writers during the Francoist exile), later to Europe (France, Switzerland) and finally within Spain (to Madrid, Catalonia or the Basque Country).
A specific 19th-century example is the Irish diaspora, beginning in the mid-19th century and brought about by Template:Lang or "the Great Hunger" of the Irish Famine. An estimated 45% to 85% of Ireland's population emigrated to areas including Britain, the United States, Canada, Argentina, Australia, and New Zealand. The size of the Irish diaspora is demonstrated by the number of people around the world who claim Irish ancestry; some sources put the figure at 80 to 100 million.
From the 1860s, the Circassian people, originally from Europe, were dispersed through Anatolia, Australia, the Balkans, the Levant, North America, and West Europe, leaving less than 10% of their population in the homeland – parts of historical Circassia (in the modern-day Russian portion of the Caucasus).<ref>Richmond, pp. 172–173.</ref>
There were two major Italian diasporas in Italian history.

In Canada, internal migration has occurred for a number of different factors over the course of Canadian history. An example is the migration of workers from Atlantic Canada (particularly Newfoundland and Labrador) to Alberta, driven in part by the cod collapse in the early 1990s and the 1992 moratorium on cod fishing. Fishing had previously been a major driver of the economies of the Atlantic provinces, and this loss of work proved catastrophic for many families. As a result, beginning in the early 1990s and into the late 2000s, thousands of people from the Atlantic provinces were driven out-of-province to find work elsewhere in the country, especially in the Alberta oil sands during the oil boom of the mid-2000s.<ref>Template:Cite journal</ref> This systemic export of labour<ref>Template:Cite journal</ref> is explored by author Kate Beaton in her 2022 graphic memoir Ducks, which details her experience working in the Athabasca oil sands.<ref>Template:Cite news</ref><ref>Template:Cite news</ref>
Template:MainInternal migration in Brazil occurs mainly for economic reasons and ecological disasters. Internal migration involves the movement of people within the same territory, which can be between regions, states or municipalities. It does not affect the total number of inhabitants in a country, but it does change the regions involved in this process. In Brazil, economic factors exert the greatest influence on migratory flows, as the capitalist production model creates privileged areas for industries, forcing people to move from one place to another in search of better living conditions and jobs to meet their basic survival needs.<ref name=":0">Template:Cite web</ref>
Some examples of internal migration in Brazil occurred in the 1960s, when the droughts devastated the Northeast of Brazil, leading thousands of people to abandon their homes in the Brazilian hinterland due to the lack of agricultural alternatives and social policies in the region. At the end of the 19th century, northeasterners migrated to the North of Brazil because of the rubber cycle.
In the 1970s, migrants from the Northeast and the South left in search of a better life in the Southeast, Brazil's only industrial center at the time.<ref name=":0" /><ref>Template:Cite web</ref>
The oldest internal migration in Italy goes back to the 11th century when soldiers and settlers from Northern Italy (at the time collectively called "Lombardy"<ref>Template:Cite web</ref>), settled the central and eastern part of Sicily during the Norman conquest of southern Italy. After the marriage between the Norman king Roger I of Sicily with Adelaide del Vasto, member of Aleramici family, many Lombard colonisers left their homeland, in the Aleramici's possessions in Piedmont and Liguria, to settle on the island of Sicily.<ref>Template:Cite book</ref><ref>These Lombard colonisers were native northern Italians and should not be confused with the Germanic tribe the Lombards, who were referred to as longobardi to distinguish them from the Italians of the region who were known as lombardi.</ref> The migration of people from Northern Italy to Sicily continued until the end of the 13th century.<ref>Template:Cite book</ref> In the same period people from Northern Italy also emigrated to Basilicata.<ref>Template:Cite book</ref> It is believed that the population of Northern Italy who immigrated to Sicily during these centuries was altogether about 200,000 people.<ref>Template:Cite web</ref> Their descendants, who are still present in Sicily today, are called Lombards of Sicily.

With the fall of Fascist regime in 1943, and the end of World War II in 1945, a large internal migratory flow began from one Italian region to another. This internal emigration was sustained and constantly increased by the economic growth that Italy experienced between the 1950s and 1960s.<ref name="uniud">Template:Cite web</ref> Given that this economic growth mostly concerned Northwest Italy, which was involved in the birth of many industrial activities, migratory phenomena affected the peasants of the Triveneto and southern Italy, who began to move in large numbers.<ref name="uniud" /> Other areas of northern Italy were also affected by emigration such as the rural areas of Mantua and Cremona. The destinations of these emigrants were mainly Milan, Turin, Varese, Como, Lecco, and Brianza.<ref name="americacallsitaly">Template:Cite web</ref> The rural population of the aforementioned areas began to emigrate to the large industrial centers of the north-west, especially in the so-called "industrial triangle, or the area corresponding to the three-sided polygon with vertices in the cities of Turin, Milan and Genoa.<ref name="uniud" /><ref name="salogentis">Template:Cite web</ref> Even some cities in central and southern Italy (such as Rome, which was the object of immigration due to employment in the administrative and tertiary sectors) experienced a conspicuous immigration flow.<ref name="uniud" />
These migratory movements were accompanied by other flows of lesser intensity, such as transfers from the countryside to smaller cities and travel from mountainous areas to the plains.<ref name="uniud" /> The main reasons that gave rise to this massive migratory flow were linked to the living conditions in the places of origin of the emigrants (which were very harsh), the absence of stable work,<ref name="salogentis" /><ref name="americacallsitaly" /> the high rate of poverty, the poor fertility of many agricultural areas, the fragmentation of land properties,<ref name="MacDonald" /> which characterized southern Italy above all, and the insecurity caused by organized crime.<ref name="americacallsitaly" /> Overall, the Italians who moved from southern to northern Italy amounted to 4 million.<ref name="uniud" /> The migratory flow from the countryside to the big cities also contracted and then stopped in the 1980s.<ref name="uniud" /> At the same time, migratory movements towards medium-sized cities and those destined for small-sized villages increased.<ref name="uniud" />
The 20th century saw huge population movements. Some involved large-scale transfers of people by government action. Some migrations occurred to avoid conflict and warfare. Other diasporas formed as a consequence of political developments, such as the end of colonialism.
After World War II, the Soviet Union and communist-controlled Poland, Czechoslovakia, Hungary and Yugoslaviaexpelled millions of ethnic Germans, most of them were the descendants of immigrants who had settled in those areas centuries ago.

The initial responses of national governments varied greatly.<ref name=":1" /> Many European Union (EU) governments reacted by closing their borders, and most countries refused to take in the arriving refugees. Germany would ultimately accept most of the refugees after the government decided to temporarily suspend its enforcement of the Dublin Regulation.
