Publisher Desc.  Cajuns are the descendants of Catholic French Canadians whom the British Empire expelled from the captured French territory of Acadia (modern-day Nova Scotia and its surrounding areas) in the 18th century. They emigrated to rural south Louisiana, territory owned by France prior to the Louisiana Purchase, which the new settlers called aAcadiana.a Modern Cajuns maintain connections to their heritage and culture through the French language and dialect, their cuisine, and their music. The Mamou Two-Step is named after the small Louisiana town of Mamou, given the epithet of aThe Cajun Music Capital of the World.a
