Gangela
Gangela is a name associated with peoples east of Angola's Bié plateau, among them the Nganguela and their neighbours the Mbunda, Lwena and Luvale. Their related languages and varied local identities belong to a broad region of woodland and rivers. From the seventeenth century, communities of this interior became involved in commerce connected to the Portuguese coastal settlements of Luanda and Benguela. Captives acquired through African intermediaries formed part of that trade.
