Emiliano Zapata was the revolutionary leader in Mexico known for his prominent role in advocating agrarian reforms during the Mexican Revolution, which started in 1910. He championed the cause of land reform, calling for the return of land to the peasants and advocating for the rights of rural communities. His slogan, "Tierra y Libertad" (Land and Freedom), encapsulated the struggle of the agrarian class against the oppressive regimes that had long exploited them. Zapata's influence was significant in shaping the course of the revolution and in pushing for social justice and land redistribution in Mexico, leaving a lasting legacy in Mexican history.
