Cap-Haïtien became the capital of the Kingdom of Northern Haiti under a king that was a former slave of what ethnicity?
Henri Christophe Henri Christophe (] ; 6 October 1767 – 8 October 1820; used the anglicized version of Henry Christopher) was a former slave of Bambara ethnicity, and perhaps of Ibo descent, and key leader in the Haitian Revolution, which succeeded in gaining independence from France in 1804. In 1805 he took part under Jean-Jacques Dessalines in the capturing of Santo Domingo (now Dominican Republic), against French forces who acquired the colony from Spain in the Treaty of Basel.
Mirambo Mtyela Kasanda, better known as Mirambo (which means "corpses"), was a Nyamwezi warlord, from 1860 to 1884. Mirambo started out as a trader, and owned trade caravans traveling from the Great Lakes region in western Tanzania to the coast, mostly dealing with ivory and slaves. Through trade with Europeans he acquired firearms and money, and organised armies consisting mostly of teenage orphans. With his newly gained power, he toppled the traditional monarchy of the kingdom Urambo, and installed himself as ntemi (king). The Nyamwezi aristocracy was appalled when someone who was not royalty took over the religiously ceremonial office of ntemi.
