>[!abstract] >_Jus sanguinis_ ("right of blood") is a legal principle under which nationality or citizenship is determined by parentage rather than birthplace. A person acquires citizenship if one or both parents are citizens of a given state, regardless of where the birth occurs. Common in many European and Asian countries, _jus sanguinis_ reflects an ethnocultural or descent-based notion of national identity, in contrast to _[[Jus soli|jus soli]]_ (right of the soil), which bases citizenship on territorial birth. The principle shapes immigration, diaspora, and dual-citizenship policies, often linking citizenship to heritage and continuity across generations. >[!related] >- **North** (upstream): [[Citizenship law]] >- **West** (similar): — >- **East** (different): [[Jus soli]] >- **South** (downstream): —
