The Reforma was a significant political and social movement in Mexico during the mid-19th century, primarily between 1855 and 1876. It aimed to modernize the country by reducing the power of the Catholic Church and the military, promoting civil rights, and establishing a secular state. Key figures in this movement included Benito Juárez and Melchor Múzquiz. The movement led to the implementation of several important laws, such as the Ley Juárez and the Ley Lerdo, which sought to limit the privileges of the church and redistribute land. The Reforma ultimately laid the groundwork for the Mexican Revolution and shaped modern Mexican society.
