Same-surname marriage is themarriage of two people of the samesurname. Historically, same-surname marriage was considered ataboo or prohibited in China and otherEast Asian cultures influenced by China.
Initially,ancient China did not have regulation onendogamy during theXia andShang dynasties. A policy against same-surname marriage was first instituted during theWestern Zhou. In his interpretation of theBook of Rites, philosopherZheng Xuan compared same-surname marriage tozoophilia, and called itblasphemous; indicating the seriousness of theZhou dynasty's opposition to it.[1]Confucianism opposed same-surname marriage because it thought that it would lead to weakness inreproduction of offspring. Both theGuoyu and theZuo zhuan attributed the lack of same-surname couples to concerns with their offspring.[2]: 22–23
Although Confucianism opposed same-clan name marriage, the taboo did not originate from Confucianism, and opposition to same-clan name marriage later gained support outside Confucianism. Same-surname marriage formed part of thetraditional Chinese marriage system, where men and women within the sameextended family were not permitted to marry, just as is the case in manypatriarchal societies.[3]
TheHan dynasty did not have anystatute prohibiting marriage between men and women of the same surname.Wang Mang's marriage toEmpress Wang indicates that same-surname marriage was not socially unacceptable during that period, if the couple do not share the samekin.Emperor Xiaowen reintroduced a law prohibiting same-surname marriage during theNorthern Wei, with a usual penalty ofcapital punishment.Tang dynasty law continued to treat same-surname marriage as a crime, punishable by two years of imprisonment.[3] TheMing andQing dynasties inherited the prohibition on same-surname marriage from Tang dynasty law; the prohibition was abolished towards the end of the Qing dynasty via judicial reforms, allowing men and women of the same surname and different kin to marry.[2]: 22 In 1950, the People's Republic of China passed itsNew Marriage Law, which reduced restrictions on same-surname marriage to lineal blood relatives.[4]
During theThree Kingdoms period, same-surname marriage was prevalent among the royal family and aristocracies of theSilla kingdom, in order to maintain the bloodline and strengthen royal authority.King Taejong Muyeol, for instance, was the son ofKing Jinji andPrincess Cheonmyeong, the daughter ofKing Jinpyeong; andQueen Jinseong married her uncle Kim Wi–Hong. Even in the earlyGoryeo dynasty, same-surname marriage in the royal family was very common, and even marriages between half-siblings were performed.
However, from the middle of the Goryeo period, due to the influence of Confucianism, marriages between close relatives started to decline, and eventually disappeared by the end of the Goryeo dynasty. During theJoseon dynasty, when Confucianism became the founding ideology of the nation, marriage between people with the same last name and ancestral family was strictly prohibited, and even marriages with relatives from the maternal blood were banned unless the parties only share a blood relative after the sixthdegree (second cousins).
The prohibition of same-surname marriage was recognized as part of Koreancustomary law during theJapanese colonial period. Following thedivision of Korea, the laws concerning family and marriage began to diverge. North Korean law does not formally ban marriage between people with the same last name, while theCivil Code ofRepublic of Korea inherited the prohibition on same-surname marriage from the colonial era.
The prohibition on same-surname marriage was continuously challenged in South Korea since the introduction of the Civil Code. Opponents argued that it was not feasible to ban such marriage simply due to surname, since the family name system in South Korea has been developed to a point where it became difficult to confirm the kinship between people with the same last name.
On 16 July 16 1997, theConstitutional Court of Korea ruled that the prohibition on same-surname marriage was inconsistent with the constitution, and the law would be suspended in 1999.[5] Currently, South Korean laws only ban marriage between people who share a blood relative within the eighth degree (third cousins), whether or not the couple in question shares the same surname.
Currently,Taiwanese law does not prohibit marriage based on shared surname, instead only prohibiting people who are related by blood within the sixth degree of relationship (second cousins). According to statistics from theMinistry of the Interior, as of 2014 there are 174,350 same-surname couples in Taiwan, including one couple with the same surname and given name.[6]
Laws during the early part of theLê dynasty included a provision prohibiting same-surname marriage, similar to the legal provision in China.[7] The phraseMiễn là cùng họ ("as long as the same surname") is often used.[8]
