Why did British, French, and Belgian troops drive Germany out of Cameroon during World War I?

During World War I, Allied forces—including British, French, and Belgian troops—drove Germany out of its colony of Kamerun as part of the broader global conflict between European powers.123

The campaign began in August 1914, with Allied forces invading the territory from the south, east, and northwest, while simultaneously attacking from the sea in the west. Unlike some other German colonies that fell quickly, the German forces in Kamerun mounted an effective resistance that lasted until February 1916, when the final stronghold at Mora surrendered.2

Following the defeat of the German colonial administration, the territory was partitioned under League of Nations mandates, which were later transitioned into United Nations trusts. This resulted in the division of the region into British Cameroons and French Cameroun, marking the end of German colonial rule in the area.134
