Gaza Empire

The Gaza Empire was an African empire established by general Soshangane and was located in southeastern Africa in the area of southern Mozambique and southeastern Zimbabwe. The Gaza Empire, at its height in the 1860s, covered all of Mozambique between the Zambezi and Limpopo rivers, known as Gazaland.
History
In the 1820s, during a period of severe drought, after the abolition of slavery caused the Great Trek, Nguni armies, Southern and especially Northern Nguni people who speak related Bantu languages and inhabit southeast Africa from Cape Province to southern Mozambique, began to migrate to Mozambique from what is now South Africa. One Nguni chief, Nxaba, established a short-lived kingdom inland from Sofala, but in 1837 he was defeated by Soshangane, a powerful Nguni rival. Eventually Soshangane established his capital in the highlands of the middle Sabi River in what is present day Zimbabwe. Soshangane named his empire "Gaza" after his grandfather.
