Jus sanguinis (English: /dʒʌs ˈsæŋɡwɪnɪs/ juss SANG-gwin-iss, /juːs -/ yoos -⁠, Latin: [juːs ˈsaŋɡwɪnɪs]; 'right of blood') is a principle of nationality law by which citizenship is determined or acquired by the nationality or ethnicity of one or both parents. Children at birth may be citizens of a particular state if either or both of their parents have citizenship of that state. It may also apply to national identities of ethnic, cultural, or other origins. Citizenship can also apply to children whose parents belong to a diaspora and were not themselves citizens of the state conferring citizenship. This principle contrasts with jus soli ('right of soil'), which is solely based on the place of birth.
