Liberalism in Mexico was part of a broader nineteenth-century political trend affecting Western Europe and the Americas, including the United States, that challenged entrenched power.
Most Mexican liberals looked to European thinkers in their formulation of their ideology, which has led to a debate about whether those ideas were merely "Mexicanized" versions. In Mexico, the most salient aspects of nineteenth-century liberalism were to create a secular state separated from the Roman Catholic Church, establish equality before the law by abolishing corporate privileges (fueros) of the church, the military, and indigenous communities. Liberals' aim was to transform Mexico into a modern secular state with a dynamic economy. Corporate privilege and the conservative elite defenders were considered stumbling blocks to the nation’s political, social, and economic progress. Secular, public education was a key element in opening paths to achievement for all Mexican citizens. Schooling historically had been the domain of the Roman Catholic Church and limited to elite men, so that broadening educational access and having a secular curriculum was seen as a way to transform Mexican society. The breakup of land owned by corporations, specifically the Roman Catholic Church and indigenous communities, was a crucial policy element in diminishing the power of the church and integrating Mexico’s Indians into the republic as citizens and transforming them into yeoman farmers. Unlike many liberals elsewhere, Mexican liberals did not call for limitations on executive power.
The term "liberal" became the name of a political faction, which previously had called itself "the Party of Progress" in contrast to the Conservative Party, which they called "the Party of Regression." Conservatives characterized themselves as those that defended Mexican tradition. Following Mexican independence from Spain in 1821, the first Mexican liberals became important on the national scene. The most prominent was secular priest and intellectual, José María Luis Mora (1794-1850), who was influenced by Montesquieu, Benjamin Constant, and Jeremy Bentham. Mora attacked corporate privilege, especially the fueros of the Roman Catholic Church; considered the role of utilitarianism (the greatest good for the greatest number) in Mexico; examined the so-called "Indian Question," of how to modernize Mexico when the majority of the population was indigenous living in rural communities; and considered the role of liberalism in economic development. The early post-independence era was dominated by General Antonio López de Santa Anna and Mexican conservatives, so that Mexican liberals were rarely able to exercise political power nationally.
