Cajuns are the descendants of Acadians who came from Nova Scotia to Louisiana as a result of their refusal to swear allegiance to the British Crown.
Cajun is an evolution of the French pronunciation of the word Acadian, the name of the original region in Nova Scotia, and the name applied to them when they settled in Louisiana.
Cajun French (derived from Acadian French) although a dialect of the French language, differs in some areas of pronunciation as well as in some areas of vocabulary with Parisian French.
