The leader of the revolutionary forces in the Mexican Revolution was Emiliano Zapata, who championed agrarian reform and social justice. Along with other key figures like Pancho Villa, Zapata fought against the longstanding oppression of the peasant class and sought to redistribute land to those who worked it. His rallying cry, "Tierra y Libertad," underscored the demands for land reform and empowerment of rural populations. The Mexican Revolution (1910-1920) ultimately sought to address injustices rooted in a long history of dictatorship and inequality, fundamentally reshaping Mexican society and governance.
