The beginning of the twentieth century coincided with the end of kruso’b autonomy. The authoritarian Mexican President Porfirio Díaz sent regular armed forces under General Ignacio Bravo to Yucatán to attack the Caste War rebels. The massive and long campaign began in 1899. Protected by three Mexican army battalions and Yucatecan militia units, peons drove a path into the area controlled by the kruso’b with clearings of up to 300 meters in width to avoid assault. Military posts were set up every ten kilometers. Although they provided some resistance, the kruso’b were unable to stop the advancing government forces. The military campaign endured for three years. Chan Santa Cruz was occupied on May 4, 1901.
