Douala is the largest city in Cameroon and its economic capital. It is also the capital of Cameroon's Littoral Region. Home to Central Africa's largest port and its major international airport, Douala International Airport, it is the commercial and economic capital of Cameroon and the entire CEMAC region comprising Gabon, Congo, Chad, Equatorial Guinea, Central African Republic and Cameroon. Consequently, it handles most of the country's major exports, such as oil, cocoa and coffee, timber, metals and fruits. As of 2010 the city and its surrounding area had an estimated population that surpassed 3,000,000 inhabitants. The city sits on the estuary of Wouri River and its climate is tropical.
Settlements had already existed in present-day Douala prior to the arrival of the Portuguese, British, and Germans; however, it was during the German colonization that the city began to develop rapidly as a commercial and political hub of the German colonial administration. During World War I a bitter battle was fought for control of Douala. The city surrendered to British and French forces on September 27, 1914.
