Pascual Orozco Vázquez, Jr. (sometimes spelled "Oroszco") (28 January 1882 – 30 August 1915) was a Mexican revolutionary leader and general during the early years of the Mexican Revolution. Orozco rose up to support Francisco I. Madero's uprising in late 1910 to depose long-time president and dictator Porfirio Díaz, who had been the nation's de facto ruler since 1876. Orozco, a natural military leader, achieved victory over the Federal Army at the Battle of Ciudad Juárez; the battle was a key factor in forcing Díaz to resign in May 1911.
After Madero was democratically elected president in November 1911, Orozco served as leader of the state militia in Chihuahua. Orozco perceived this as a paltry reward for his services in the Mexican Revolution, and he revolted against the Madero government 16 months later, issuing the Plan Orozquista in March 1912. The Federal Army struggled to suppress Orozco's revolt throughout 1912. When Victoriano Huerta led a coup d'état against Madero in February 1913 during which Madero was murdered, Orozco joined the Huerta regime.
