Eutimio Mambí
Juan Ethnnius Mamby was a black officer of the Spanish Army who arrived in the Dominican Republic at some point in 1810s. In the 1840s, however, he deserted the Spanish and enlisted in the Dominican Army to fight in the Dominican War of Independence and the Dominican Restoration War. According to Elmore Leonard, he is said to have been the origin of the word, Mambises, which is used to refer to independence fighters from the Dominican Republic and Cuba.
