19th Century: (Interlacustrine Commerce and Conflict — Buganda’s Pragmatic Mix of Trade and War, the Volatility Introduced by Zanzibar-Directed Long-Distance Commerce from the 1840s, Rwanda and Burundi’s Self-Imposed Isolation, and the Emergence of New Military Leaders Among the Nyamwezi, Kimbu, Maasai, Kamba, and Kikuyu Where Centralized States Had Been Absent): In the nineteenth century, interlacustrine states engaged with one another through both warfare and trade. Buganda’s relations with its neighbors were pragmatic — trade and economic influence where possible, conflict when necessary, as the kingdom sought to build both a territorial and an informal empire. Despite recurrent conflict, Buganda depended on healthy economic relations with Bunyoro, the Soga, the pastoral states to the west, and numerous smaller polities. Inter-state relations across the region became more volatile and more violent with the expansion of Zanzibar-directed long-distance commerce — control of trade and its benefits increasingly drove interlacustrine relations, while trade itself had major social and political consequences from the 1840s onward. Only Rwanda and Burundi resisted involvement for much of the century, giving rise to their reputations for self-imposed isolation. Across modern Kenya and Tanzania, there were few centralized states before mid-century — soils were thin, rainfall unreliable, and population densities low, so conditions for elaborate state formation were absent. Among the Nilotic pastoralists of the Kenyan interior, including the Maasai, age-regiment organization was more important than centralized political control. Yet as the century progressed and coastal commerce spread inland, new forms of political organization emerged — leaders appeared, usually military, with greater personal power than previously, to shape and exploit new structures. This was famously true among the Nyamwezi and the Kimbu, and a similar pattern developed in Kenya among the Kamba and Kikuyu, who both fought and intermarried with the Maasai.
