Jus soli was part of the common law. It was different to jus sanguinis, from the Roman law that became part of the civil-law systems of continental Europe. Where it exists, there are often conditions. For example, some countries deny citizenship to children of foreign diplomats.
Almost all states in Europe, Asia, Africa and Oceania grant citizenship at birth based upon the principle of jus sanguinis (right of blood). Citizenship is inherited through parents not by birthplace. Sometimes it can be a version of jus soli in which citizenship by birthplace is automatic only for the children of certain immigrants.
