  The occupation of Egypt and the acquisition of the Congo were the first major moves in what came to be a precipitous scramble for African territory. In 1884, Otto von Bismarck convened the 1884–1885 Berlin Conference to discuss the African problem. While diplomatic discussions were held regarding ending the remaining slave trade as well as the reach of missionary activities, the primary concern of those in attendance was preventing war between the European powers as they divided the continent among themselves. More importantly, the diplomats in Berlin laid down the rules of competition by which the great powers were to be guided in seeking colonies. They also agreed that the area along the Congo River was to be administered by Leopold II as a neutral area in which trade and navigation were to be free. No nation was to stake claims in Africa without notifying other powers of its intentions. No territory could be formally claimed before being effectively occupied. However, the competitors ignored the rules when convenient, and on several occasions war was only narrowly avoided (see Fashoda Incident). The Swahili coast territories of the Sultanate of Zanzibar were partitioned between Germany and Britain, initially leaving the archipelago of Zanzibar independent until 1890, when that remnant of the Sultanate was made into a British protectorate with the Heligoland–Zanzibar Treaty.
