Madero and Villa in the ouster of Díaz

At the outbreak of the Mexican Revolution, for Villa and men like him operating as bandits, the turmoil provided expanded horizons, "a change of title, not of occupation" in one assessment. Villa joined in the armed rebellion that Francisco Madero called for in 1910 to oust incumbent President Porfirio Díaz in the Plan de San Luis Potosí. In Chihuahua, the leader of the anti-re-electionists, Abraham González, reached out to Villa to join the movement. Villa captured a large hacienda, then a train of Federal Army soldiers, and the town of San Andrés. He went on to beat the Federal Army in Naica, Camargo, and Pilar de Conchos, but lost at Tecolote. Villa met in person with Madero in March 1911, as the struggle to oust Díaz was ongoing. Although Madero had created a broad movement against Díaz, he was not sufficiently radical for anarcho-syndicalists of the Mexican Liberal Party, who challenged his leadership. Madero ordered Villa to deal with the threat, which he did, disarming and arresting them. Madero rewarded Villa by promoting him to colonel in the revolutionary forces.

Much of the fighting was in the north of Mexico, near the border with the United States. Fearful of U.S. intervention, Madero ordered his officers to call off the siege of the strategic border city of Ciudad Juárez. Villa and Pascual Orozco attacked instead, capturing the city after two days of fighting, thus winning the first Battle of Ciudad Juárez in 1911.

Facing a series of defeats in many places, Díaz resigned on 25 May 1911, afterward going into exile. However, Madero signed the Treaty of Ciudad Juárez with the Díaz regime, under which the same power structure, including the recently defeated Federal Army, was retained.
