diaspora

A diaspora is a population dispersed across multiple regions outside its geographic place of origin, typically comprising people who continue to identify—culturally, politically, religiously, or emotionally—with a particular homeland while residing elsewhere. The term originates from the ancient Greek διασπορά, which was first used in reference to the Jewish exile following the Babylonian captivity. The term now broadly encompasses communities formed through voluntary migration as well as through forced displacement caused by conquest, persecution, enslavement, famine, or war.
