Cameroon is home to more than 200 different linguistic groups. French and English are the official languages. The country is often referred to as "Africa in miniature" for its geological and cultural diversity. The largest cities in population-terms are Douala, Yaoundé (the capital), and Garoua. Kamerun became a German colony in 1884. After World War I, the territory was divided between France and the United Kingdom as League of Nations mandates. In 1960, the French-administered part of Cameroon became independent as the Republic of Cameroun, and the southern part of British Cameroons merged with it in 1961.
