When the Spanish arrived in the 16th century, they found the indigenous peoples divided into Mayan and non-Mayan, with the latter dominated by the Zoques and Chiapa. The first contact between Spaniards and the people of Chiapas came in 1522, when Hernán Cortés sent tax collectors to the area after Aztec Empire was subdued. The first military incursion was headed by Luis Marín, who arrived in 1523. After three years, Marín was able to subjugate a number of the local peoples, but met with fierce resistance from the Tzotzils in the highlands. The Spanish colonial government then sent a new expedition under Diego de Mazariegos. Mazariegos had more success than his predecessor, but many natives preferred to commit suicide rather than submit to the Spanish. One famous example of this is the Battle of Tepetchia, where many jumped to their deaths in the Sumidero Canyon.
