Since the late 16th century, the Jesuits had been attempting to evangelize the Tehuecos people in what is now north-western Mexico. From the outset, the Tehuecos resisted conversion to Christianity, rejecting both the religious and cultural impositions of the missionaries. In 1597, tensions escalated into open conflict that lasted for six months. The immediate spark occurred during Lent, when a Jesuit priest discovered stone idols in a Tehueco village and ordered their destruction. In response, local leaders warned of an impending calamity and initiated a series of traditional religious ceremonies, blaming the Jesuits for the misfortunes to come and issuing threats against the priest. While some individuals attempted to burn down the church and desecrate Christian images, a group of Tehueco men fled the village and allied with the neighboring Tepague people to form a resistance force. A Spanish military expedition was then assembled to pursue the rebels, who had taken refuge roughly 40 miles away. The campaign lasted over six weeks, during which the Spanish forces suffered from disorientation and hunger, but ended in a decisive battle on August 16, in which the rebels were defeated with heavy casualties. Seven were captured, tried, and sentenced to death by hanging. Two leaders were beheaded and their bodies burned publicly as a warning to the Tehuecos people. The uprising marked a violent episode of cultural and religious resistance during the early phase of Jesuit missionary efforts in the region.
