In 1892, the Mexican dictator Porfirio Díaz exiled Teresa Urrea from Mexico. He called her the most dangerous girl in Mexico. She was only 19 years old. Teresa Urrea was a “curandera,” or a healer, a feminist, and a revolutionary. She was born in 1873 in Sinaloa, Mexico. Her mother was Cayetana Chávez, a part-Tehueco Indigenous woman, who worked in the ranch of Don Tomás Urrea, a rich hacendado, and Teresa’s father. Cayetana Chávez was only 14 years old when she gave birth to Teresa.
