Mirambo was a leader of the Nyamwezi, an ethnic group in Tanzania, from 1860 to 1884, during a period of European colonial expansion. He regarded the Europeans as vehicles to his success. Europeans supplied him with knowledge, influence, and guns, and slaves produced food for his armies and traders. He dominated vast territories, including areas with elephant populations, which gave him access to ivory that could be traded to the Europeans. Wikipedia
