The Caste Wars of the Yucatán tore apart the peninsula between 1847 and 1901. While the violence was not constant throughout the more than five decades between the start and conclusion of the war itself, the threat of rebel hostilities was ever present. Scholars have debated the origins of the war for many decades, with most recent academic treatments focusing on heavy tax burdens, poor working conditions for Yucatán’s peasantry, and the loss of land that occurred during the second half of the century. Tensions between political leaders exacerbated relations with the Mayas in particular and the peasantry more generally. The emergence of the breakaway state of Chan Santa Cruz, in the southeastern part of Yucatán, allowed rebel forces to coalesce between 1850 and the early 1870s. Here, a “Speaking Cross” oracle gave direction to the rebellious Mayas, who crushed their enemies and exacted revenge against those who would not support their cause. The emergence of Porfirio Díaz as President of Mexico in 1876 led to a gradual “reconquest” of the areas held by the cruzob, or “people of the Cross.” By 1901, the Mexican military ended the Caste Wars, though violent episodes still marred Yucatán until the early 1930s.
