The Plan of Ayala (Spanish: Plan de Ayala) was a document drafted by revolutionary leader Emiliano Zapata during the Mexican Revolution. In it, Zapata denounced President Francisco I. Madero for his perceived betrayal of the revolutionary ideals, embodied in Madero's Plan de San Luis Potosí, and set out his vision of land reform. The Plan was first proclaimed on November 25, 1911 in the town of Ayala, Morelos, and was later amended on June 19, 1914.John Womack calls the Plan the Zapatistas' "Sacred Scripture".
Emiliano Zapata had supported Francisco I. Madero against the regime of Porfirio Díaz. Díaz was deposed and Madero was elected president. He took office on June 7, 1911, and soon after had a meeting with Zapata where he demanded the disarmament of Zapata's army as a precondition for discussion of agrarian reform. Unsatisfied, Zapata returned to Morelos arguing that if the people were not able to achieve justice after rising in arms, there was no guarantee they would achieve it without them. Finally, after Madero's appointment of a governor who supported plantation owners and his failure to settle the land issue to Zapata's satisfaction, Zapata mobilized his army again.
The Plan was drafted with the help of local schoolteacher—and Zapata's mentor—Otilio Montaño Sánchez. It detailed Zapata's ideology and vision succinctly in the cry ""Reforma, Libertad, Justicia y Ley!" ("Reform, Freedom, Justice and Law!"), later (after Zapata's death) shortened to "Tierra y Libertad!" ("Land and Freedom!", a phrase first used by Ricardo Flores Magón as the title for one of his books).
The Plan contains fifteen points, summarized here:
The June 1914 amendment was prompted by Pascual Orozco's alliance with the Victoriano Huerta regime and therefore betrayal of the revolutionary movement. This shift in alliances forced Zapata to become head of the Revolution. The amendment ratified the original intent of the Plan and called for a continuation of the conflict until the overthrow of Victoriano Huerta —who had ordered Madero's murder—and the establishment of a government loyal to the principles of the Plan.
