On February 9, 1913, during the Decena Trágica, the military revolt against President Francisco I. Madero, about 300 cadets of the Colegio Militar escorted the president from Chapultepec Castle to the National Palace. Eight days later, Madero and Vice President José María Pino Suárez were arrested.
Mexico commemorates the day every year as the Marcha de la Lealtad, the March of Loyalty. The Ministry of National Defense presents it as the army’s loyalty to a civilian and democratic mandate.
