History
Before colonial rule the land between the Nile and Mount Elgon was divided among many peoples. Busoga, just east of the river, was a patchwork of small Bantu-speaking chiefdoms under the influence of Bunyoro and later Buganda; on the mountain the Bagisu farmed the fertile southern slopes and the Sabiny the north; and the Nilotic Iteso had spread across the plains around Lake Kyoga by the 19th century. The explorer John Hanning Speke reached the outflow of Lake Victoria in 1862 and identified it as the source of the Nile.
In the 1890s and 1900s the British, often through the Ganda general Semei Kakungulu, who established Mbale as his base, extended control over the east. Cotton became the region's cash crop, and Jinja grew as a lakeside railhead and port. The Owen Falls Dam, completed in 1954, drew factories to Jinja for its power, and the Kakira sugar works nearby grew into the town's largest employer.
Idi Amin's expulsion of Uganda's Asian minority in 1972 was followed by a steep fall in national manufacturing output, and Jinja's factories declined. In the 1980s cattle raids by armed Karimojong herders decimated Teso's herds, and an insurgency against the new government lasted from 1987 to 1992. Since the 2000s Jinja has recovered as a river-tourism centre, although the Bujagali dam, finished in 2012, drowned the falls that gave the rafting scene its name, and the Isimba dam further downstream followed in 2019. Jinja and Mbale are both now cities, Jinja since 2020.
