The Treaty of Utrecht resulted in the relinquishing of French claims to mainland Acadia, the Hudson Bay and Newfoundland, and the establishment of the colony of Île Royale, now called Cape Breton Island, where the French built the Fortress of Louisbourg. Acadia had a difficult history, with the Great Upheaval, remembered on July 28 each year since 2003. The descendants are dispersed in the Maritime Provinces of Canada, in Maine and Louisiana in the United States, with small populations in Chéticamp, Nova Scotia and the Magdalen Islands.
