The population is about 84% Hutu, a Bantu people, traditionally farmers. The Tutsi, a warrior people, constitute about 15% of the total population, but many have fled into neighboring territories for refuge, especially since civil strife began in 1959. The Tutsi migrated to Rwanda sometime before the 15th century. There are also some Twa, a Pygmy tribe of hunters related to the Pygmies of the DROC; the earliest known inhabitants of the region; they now constitute about 1% of the population of Rwanda. There are also small numbers of Asians and Europeans.
