Taking its name from Cape Breton, the most easterly point of the island which was called after either the Bretons of England or the Bretons of Brittany, this municipality has what is probably the oldest surviving European name to have been used to designate part of North America. By proclamation of October 17, 1763 after termination of the Seven Years War, Cape Breton Island 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.
From 1784 to 1820 Cape Breton Island was a separate colony with a Lieutenant Governor and a nominated Council, but without an elected house of assembly. Not until after Cape Breton was reannexed to Nova Scotia in 1820 did it get representation in a house of assemblv.
Although subdivided into three districts in 1824, Cape Breton County was co-extensive with Cape Breton Island from 1820 to 1835 when the county was divided into three separate and distinct counties - Cape Breton (Northeastern District), Richmond (Southern District) and Juste au Corps (Northwest District) later called Inverness.
In 1851 Victoria County was formed out of part of Cape Breton County and a year later, in 1852, the boundaries of Cape Breton County were redefined.
NovaScotia is one of the maritime provinces of Canada.
In the counties lying along the Bay of Fundy and penetrated by the inlets are valuable dike-lands begun by the early French settlers, and continued after the expulsion of the Acadians by the colonists from New England, who in 1760 and 1761 took possession of the lands of the expelled Acadians.
The Province of NovaScotia is divided into two dioceses: the Archdiocese of Halifax, which embraces the eleven westernmost counties of the province; and the Diocese of Antigonish, which embraces the four counties on CapeBreton Island, and the Counties of Guysborough, Pictou, and Antigonish on the peninsula.
