The French Imperial Colony of Algeria, commonly referred to as French Algeria or simply Algeria, is a large, semi-autonomous North African holding of the French Empire. It currently has a population of nearly 55 million, making it France's most populous colony after Hindustan. The capital of Algeria is Algiers, and other major cities include Tunis, Oran, Constantine and Sfax. It is formed primarily out of the old Barbary States of Algiers and Tunis, and thus the most commonly spoken language is Arabic and the predominant religion is Islam, although French is the official language and there is a sizable Roman Catholic minority, especially in the cities. In 2007, as per Emperor Maurice Napoleon I's Colonial Reforms, Algeria, along with Canada, became the first French Colonies to receive complete home-rule status, although the Parliaments of both colonies are still subservient to Paris.
