The La Reforma War was a civil conflict in Mexico that took place between 1857 and 1861, centered around the struggle between liberal and conservative factions over the implementation of liberal reforms. This war marked a pivotal moment in Mexican history as it was fueled by tensions surrounding land reform, church-state relations, and the role of the military in society, which were central issues during the broader liberal reforms in Mexico aimed at modernizing the nation and reducing the power of the church and military.
