Cajun, dictionaries generally define Cajun as “a Louisanian who from ancestry consists of a mixture of many ethnic groups. Most early Acadians originated in the Centre-Ouest region of France, but others came from families of Spanish, Irish, Scottish, English, Basque, and in a few instances, American Indian Heritage.
After their 1755 expulsions from Nova Scotia, Acadians seeking refuge in South Louisiana again intermixed with other ethnic groups, particularly with French, Spanish, German, and later, Anglo-American settlers, as well as Indians (albeit to a lesser extent). Cajuns borrowed much of their culture from their black Creole neighbors. This cross-cultural pollination in Acadia and South Louisiana changed many dissimilar ethnic groups into a single new ethnic group – the Cajuns. Cajuns thus derive not only from French-speaking Acadians, but from several ethnic groups over which Acadians, culture prevailed (at least until this century, when Cajuns underwent a wide-spread process of rapid Americanization).
Yes, this very popular slice of Americana know to most outsiders as simply “Cajun Country” is really a true gumbo of cultures which make Louisiana the iconic, mysterious & heavily misunderstood place it has been for centuries.
