Msiri (c. 1830 – December 20, 1891) founded and ruled the Yeke Kingdom (also called the Garanganze or Garenganze kingdom) in south-east Katanga (now in DR Congo) from about 1856 to 1891. His name is sometimes spelled 'M'Siri' in articles in French. Other variants are "Mziri", "Msidi", and "Mushidi"; and his full name was Mwenda Msiri Ngelengwa Shitambi.
Msiri was a Nyamwezi (also known as "Yeke" or "Bayeke") from Tabora in Tanzania and a trader, like his father Kalasa, involved in the copper, ivory and slave trade controlled by the Sultan of Zanzibar and his Arab and Swahili agents. The main trade route went to Ujiji on Lake Tanganyika and then to Lake Mweru and Katanga.
Msiri realised access to guns was the key to power, and in Katanga, he had copper and ivory resources to trade for them. He formed a militia and started to conquer his neighbours. He also married into the Luba royal family, starting his practice of using wives as spies.
He depended on the east coast trade for his guns and gunpowder, which passed through the territory of his rivals, making supplies expensive and unreliable. Instead he turned to the west coast, sending his nephew Molenga to the Ovimbundu and Portuguese traders around Benguela in Angola, and a trader there called Coimbra became his supplier. The Luba people to his north-west had controlled the west coast trade, but Msiri took it over and halted their southwards expansion.
