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.
René Héctor Émile Chazal René Héctor Émile Chazal was a French colonial administrator. He served as lieutenant governor of Mauritania from 21 November 1929 to 19 June 1931. French soldier and former governor of Mauritania Henri Gaden sharply criticized Chazal's appointment, writing, "Chauzal knows nothing about Mauritania, nor the Moors, nor about any other populations of this type. While governor, Chazal imprisoned spiritual leader Yacouba Sylla, whom he considered a great threat. It is likely that Chazal was dismissed as lieutenant governor due to a pamphlet by Louis Hunkanrin that sharply criticized his approach to slavery.
