===Distant origins===
It is commonly held that the Hakkas are a subgroup of the Han Chinese that originated in the central plains.<ref>{{cite book|last1=Constable|first1=Nicole|title=Guest People: Hakka Identity in China and Abroad|date=2005|publisher= Univ. of Washington Press|location=Seattle|isbn=9780295984872|page=9}}</ref><ref name=hu-sp/> To trace their origins, a number of theories so far have been brought forth among anthropologists, linguists and historians:<ref name=wang/>

#the Hakkas are Han Chinese originating solely from the [[Central Plain (China)|Central Plain]];<ref name=wang/>
#the Hakkas are northern Han Chinese from the Central Plain with some inflow of Han Chinese from the south;<ref name=wang/>
#the Hakkas are southern Han Chinese with some inflow of northern Han Chinese from the Central Plain.<ref name=wang/>

The theories indicating a descent from both northern and southern Han are the most likely and are together supported by multiple scientific studies into the genetics.<ref name=hu-sp>{{cite journal|last=Hu|first=SP|author2=Luan, JA|author3=Li, B|author4=Chen, JX|author5=Cai, KL|author6=Huang, LQ|author7=Xu, XY|title=Genetic link between Chaoshan and other Chinese Han populations: Evidence from HLA-A and HLA-B allele frequency distribution|journal=American Journal of Physical Anthropology|date=January 2007|volume=132|issue=1|pages=140–50|pmid=16883565|doi=10.1002/ajpa.20460}}</ref><ref name=wang>{{cite journal|last=Wang|first=WZ|author2=Wang, CY|author3=Cheng, YT|author4=Xu, AL|author5=Zhu, CL|author6=Wu, SF|author7=Kong, QP|author8=Zhang, YP|title=Tracing the origins of Hakka and Chaoshanese by mitochondrial DNA analysis|journal=American Journal of Physical Anthropology|date=January 2010|volume=141|issue=1|pages=124–30|pmid=19591216|doi=10.1002/ajpa.21124|doi-access=free}}</ref><ref name="Chen">{{cite journal |last=Chen |first=Jieming |author2=Zheng, Houfeng |author3=Bei, Jin-Xin |author4=Sun, Liangdan |author5=Jia, Wei-hua |author6=Li, Tao |author7=Zhang, Furen |author8=Seielstad, Mark |author9=Zeng, Yi-Xin |author10=Zhang, Xuejun |author11=Liu, Jianjun |date=1 December 2009 |title=Genetic Structure of the Han Chinese Population Revealed by Genome-wide SNP Variation |journal=The American Journal of Human Genetics |volume=85 |issue=6 |pages=775–785 |doi=10.1016/j.ajhg.2009.10.016 |pmc=2790583 |pmid=19944401}}</ref> Furthermore, research into the mitochondrial DNA of the Hakka indicates that the majority of their matrilineal gene pool consists of lineages prevalent in the southern Han.<ref name=wang/> Clyde Kiang stated that the Hakkas' origins may also be linked with ancient neighbors of the Han, the [[Dongyi]] and [[Xiongnu]] people.<ref>{{cite web| url=http://www.taiwandocuments.org/language.htm|title=Related Topics: Non-legal Considerations: Language|publisher=Taiwandocuments.org|access-date=15 January 2015}}</ref> However, this is disputed by many scholars and Kiang's theories are considered to be false.<ref>{{cite book|last=Cheung|first=Sidney C.H.|title=On the south China track: Perspectives on anthropological research and teaching|year=1998|publisher=Hong Kong Institute of Asia-Pacific Studies, Chinese University of Hong Kong|location=Hong Kong|isbn=978-962-441-540-7|page=160}}</ref>

Hakka Chinese scientist and researcher Dr. Siu-Leung Lee stated in the book by Chung Yoon-Ngan, ''The Hakka Chinese: Their Origin, Folk Songs And Nursery Rhymes'', that the potential Hakka origins from the Northern Han and [[Xiongnu]] and that of the indigenous Southern [[She people|She]] and [[Baiyue|Yue]] tribes, "are all correct, yet none alone explain the origin of the Hakka", pointing out that the problem with [[DNA profiling]] on limited numbers of people within population pools cannot correctly ascertain who is really the Southern Chinese, because many Southern Chinese are also from Northern Asia; Hakka or non-Hakka.<ref>{{cite book|last=Choon|first=Yoon Ngan|title=The Hakka Chinese: Their Origin, Folk Songs And Nursery Rhymes|year=2005|publisher=Poseidon Books|location=BURLEIGH MDC QLD. 4220, AUSTRALIA|isbn=978-1-921005-50-3}}</ref> It is known that the earliest major waves of Hakka migration began due to the attacks of the two aforementioned tribes during the [[Jin dynasty (266–420)]].<ref name="Pioneers">{{cite book|last=Lee|first=Khoon Choy|title=Pioneers of modern China : understanding the inscrutable Chinese|year=2006|publisher=World Scientific Publishing|location=River Edge, New Jersey|page=62|isbn=9789812566188|url=https://books.google.com/books?id=1jlOQc8BumIC&q=peru+20%2C000+Britain+15%2C200%2C+Vietnam+15.000&pg=PA65}}</ref>
