Ties That Bind: The Long Emancipation And Status Ambiguity In Early 20th-Century Southwestern Tanzania, Lydia (Wilson) Marshall, Thomas John Biginagwa

Sociology & Anthropology Faculty publications

In the 1890s, the slave and ivory trader Rashid bin Masoud established the settlement Kikole deep in what is now southwestern Tanzania. Kikole was strategically located near Lake Nyasa, a major slaving region. Masoud's followers residing at Kikole were typically referred to as his slaves by German colonists and missionaries. Local oral histories today, however, define these followers as askari (soldiers or guards) or mafundi (technicians or specialists; in this case, in using weaponry). This article considers how recent expanded excavations at Kikole can help us better understand Masoud's followers. Differences in housing investment and material access suggest status differences …
