The Liberal Reform in Mexico refers to a series of political, social, and economic reforms that were implemented in the mid-19th century, primarily during the presidency of Benito Juárez. These reforms aimed to reduce the power of the Catholic Church and the military, promote secularism, and modernize Mexico's economy through land redistribution and the establishment of a free-market system. The Liberal Reform significantly shaped Mexico's political landscape and had long-lasting effects on its society.
