The discovery of the mines of Parral, Chihuahua, in 1631 increased Spanish presence in Tarahumara lands, bringing more slave raids and Jesuit missionaries. Missions were established at Las Bocas, Huejotitlan, San Felipe and Satevo. In 1648, the Tarahumara waged war against the Spanish. They gathered at Fariagic and then destroyed the mission of San Francisco de Borja. Two of the leaders of this attack were captured by the Spanish and executed. Shortly afterward, the Spanish established Villa de Aguilar in the heart of the upper Tarahumara country.
