In New Mexico, there was also significant ethnic violence in the 1890s. It began when the Santa Fe Ring, a group of powerful Anglo lawyers and land speculators, succeeded in dispossessing thousands of Mexican Americans of lands they used for community farming. The Ring moved quickly to fence the lands to prevent anyone from accessing the areas. In response, a group called Las Gorras Blancas initiated a lawsuit against the Ring arguing for community access to the Las Vegas Land Grant, but the judge sided with the Santa Fe Ring. The Gorras Blancas, outraged at the injustice, promised military retribution. In 1890, they began their campaign of vigilante justice, cutting down the new fences, destroying farm equipment, and burning buildings throughout San Miguel, Santa Fe, and Mora counties. Believed to have been led by the three Herrera brothers, Juan José (known as El Capitan), Pablo, and Nicanor, the Gorras Blancas held between 700 and 1,500 members at its height. In 1890, the Blancas declared themselves the defenders of "the rights of all people in general, and especially the rights of poor people." The territorial Governor Lebaron Bradford Prince responded by declaring them a violent "mob," and organized officials to clamp down on the group. Four dozen Gorras Blancas were indicted, but none were convicted. Finally, in Arizona, racial violence also erupted in 1896 with the Yaqui Uprising, when a group of Yaqui, Pima, and Mexican revolutionaries fought against the U.S. and Mexican armies in an early attempt to overthrow the increasingly despotic President Porfirio Díaz.
