All the former colonies and territories that became involved in the Canadian Confederation on July 1, 1867, were initially part of New France, and were once ruled by France. Nova Scotia was granted in 1621 to Sir William Alexander under charter by James VI. This claim overlapped the French claims to Acadia, and although the Scottish colony of Nova Scotia was short-lived, for political reasons, the conflicting imperial interests of France and the 18th century Great Britain led to a long and bitter struggle for control. The British acquired present-day mainland Nova Scotia by the Treaty of Utrecht of 1713 and the Acadian population was expelled by the British in 1755. They renamed Acadia "Nova Scotia", which included present-day New Brunswick. The rest of New France was acquired by the British as the result of its defeat of New France in the Seven Years' War, which ended with the Treaty of Paris in 1763. From 1763 to 1791, most of New France became the Province of Quebec. However, in 1769 the present-day Prince Edward Island, which had been part of Acadia, was renamed "St John's Island" and organized as a separate colony. It was renamed "Prince Edward Island" in 1798 in honour of Prince Edward, Duke of Kent and Strathearn.
