Cajun and folk music have a lot in common and are often compared to each other. Mostly because they are both ever-evolving histories of a certain people.
South Louisiana has multiple dialects that come from the French language. There are three main dialects: the French that came from the French descendants who first settled Louisiana in 1699, the Creole which came from intermixing of African settlers and the Acadians that wandered south to New Orleans, and Cajun French that came from the Acadians who settled in the grasslands and bayous. The languages reflect the areas where the groups had settled and had frequent interactions. After the Louisiana Purchase, French Louisiana was forced to adapt the language and culture of the United States and their languages were not passed down to their children.
