jus sanguinis

Jus sanguinis, meaning 'right of blood', is a principle of nationality law by which nationality is determined or acquired by the nationality of one or both parents. Children at birth may be nationals of a particular state if either or both of their parents have nationality 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
