To understand a diaspora's politics, one must first understand its historical context and attachments.Ambrosio, Thomas. 2002."Ethnic identity groups and U.S. foreign policy." Praeger Publishers. A diaspora is a transnational community that defined itself as a singular ethnic group based upon its shared identity. Diasporas result from historical emigration from an original homeland. In modern cases, this migration can be historically documented, and the diaspora associated with a certain territory. Whether this territory is in fact the homeland of a specific ethnic group, is a political matter. The older the migration, the less evidence there is for the event: in the case of the Romani people the migration, the homeland, and the migration route have not yet been accurately determined. A claim to a homeland always has political connotations and is often disputed.
