Cape Breton Island
By proclamation of October 17, 1763, after termination of the Seven Years' War, Île Royale was renamed Cape Breton Island and was formally annexed to Nova Scotia. For a time thereafter Cape Breton Island was part of Halifax County. On December 10, 1765, Cape Breton Island was set apart as a separate county. In 1784, the island was made a separate colony with its capital at Sydney however by 1820 the colony was remerged into Nova Scotia.
