The term "Acadian" refers to the descendants of French colonists who settled in the region of Acadia, which includes parts of present-day Canada and the northeastern United States. Acadians have a unique culture that blends French, Indigenous, and English influences, and they primarily speak Acadian French. In the 18th century, many Acadians were forcibly removed from their lands during the Great Expulsion, leading to a diaspora that spread Acadian culture to various regions, including Louisiana, where they are known as Cajuns. Today, Acadians celebrate their heritage through music, dance, and festivals.
