MOXOS, Mojos, Mohos, a tribe of South American Indians living around the head-waters of the Maidera river, northern Bolivia, particularly on both sides on the Mamoré. They submitted to Inca domination, but in 1564 gallantly repulsed the Spaniards. A century later, however, the Jesuits were welcomed, and the Moxos became devout Catholics. They number some 30,000.
