The "Great Expulsion" refers to the mass removal of the Acadians, French settlers in Nova Scotia, from their homes during the mid-18th century. This event occurred between 1755 and 1764, driven by British colonial authorities who feared the Acadians would side with the French during the French and Indian War. As a result, thousands of Acadians were forcibly deported to various locations, including New England, France, and the Caribbean. Many families were separated, and the expulsion had lasting effects on Acadian culture and identity, leading to a significant diaspora and the eventual establishment of Acadian communities in new regions.
