Pascual Orozco Vázquez, Jr. was a Mexican revolutionary leader who rose up to support Francisco I. Madero in late 1910 to depose long-time president Porfirio Díaz (1876-1911). Orozco was a natural military leader whose victory over the Federal Army at Ciudad Juárez was a key factor in forcing Díaz to resign in May 1911. Following Díaz's resignation and the democratic election of Madero in November 1911, Orozco served Madero as leader of the state militia in Chihuahua, a paltry reward for his service in the Mexican Revolution. Orozco revolted against the Madero government 16 months later, issuing the Plan Orozquista in March 1912. It was a serious revolt which the Federal Army struggled to suppress. When Victoriano Huerta led a coup d'état against Madero in February 1913 during which Madero was murdered, Orozco joined the Huerta regime. Orozco's revolt against Madero somewhat tarnished his revolutionary reputation, but his subsequent support of Huerta compounded the repugnance against him.

Francisco I. Madero González was a Mexican businessman, revolutionary, writer and statesman, who served as the 37th president of Mexico from 1911 until he was deposed in a coup d'état in February 1913 and assassinated. He came to prominence as an advocate for democracy and as an opponent of President and de facto dictator Porfirio Díaz. After Díaz claimed to have won the fraudulent election of 1910 despite promising a return to democracy, Madero started the Mexican Revolution to oust Díaz. The Mexican revolution would continue until 1920, well after Madero and Díaz's deaths, with hundreds of thousands dead.
