Belgian interest soon concentrated on the Congo River, the British and Germans focused on Eastern Africa and in 1886 partitioned continental East Africa between themselves; the Sultanate of Zanzibar, now reduced to the islands of Zanzibar and Pemba, remained independent, for the moment. The Congo Free State was eventually to give up its claim on Kigoma (its oldest station in Central Africa) and on any territory to the east of Lake Tanganyika, to Germany. German East Africa All resistance to the Germans in the interior ceased and they could now set out to organize German East Africa. They continued brutally to exercise their authority with disregard and contempt for existing local structures and traditions. While the German colonial administration brought cash crops, railroads, and roads to Tanganyika, European rule provoked African resistance. Between 1891 and 1894, the Hehe—led by Chief Mkwawa—resisted German expansion, but were eventually defeated. After a period of guerrilla warfare, Mkwawa was cornered and committed suicide in 1898. Maji Maji resistance Widespread discontent re-emerged, and in 1902 a movement against forced labour for a cotton scheme rejected by the local population started along the Rufiji River. The tension reached a breaking point in July 1905 when the Matumbi of Nandete led by Kinjikitile Ngwale revolted against the local administrators (akida) and suddenly the revolt grew wider from Dar Es Salaam to the Uluguru Mountains, the Kilombero Valley, the Mahenge and Makonde plateaux, the Ruvuma in the southernmost part and Kilwa, Songea, Masasi, and from Kilosa to Iringa down to the eastern shores of Lake Nyasa. The resistance culminated in the Maji Maji Resistance of 1905–1907. The resistance, which temporarily united a number of southern tribes ended only after an estimated 300,000 Africans had died from fighting or starvation. Research has shown that traditional hostilities played a large part in the resistance. Germans had occupied the area since 1897 and totally altered many aspects of everyday life. They were actively supported by the missionaries who tried to destroy all signs of indigenous beliefs, notably by razing the 'mahoka' huts where the local population worshiped their ancestors' spirits and by ridiculing their rites, dances and other ceremonies. This would not be forgotten or forgiven; the first battle which broke out at Uwereka in September 1905 under the Governorship of Count Gustav Adolf von Götzen turned instantly into an all-out war with indiscriminate murders and massacres perpetrated by all sides
