Here's a breakdown:
* Origins: Cajuns are descendants of French-speaking Acadians who were expelled from Nova Scotia (then part of British North America) in the 18th century.
* Migration: They migrated to Louisiana, where they developed their unique culture and language.
* Nationality: Cajuns are primarily American citizens. However, they have a strong connection to their French heritage and the Acadian community.
It's incorrect to say that Cajuns have a "real" nationality. They are Americans with a rich and unique cultural background.
