Genovevo de la O (January 3, 1876 – June 12, 1952) was an important figure in the Mexican Revolution. He was born in Santa María Ahuacatitlán, Morelos, to sharecropper parents. He was dedicated to the plight of Mexico's peasants and came to be an outstanding Liberation Army of the South guerrilla general. After Emiliano Zapata's death, he and the other guerrillas threw their lot in with Álvaro Obregón and went on to become a minor but longlasting figure in national politics.
