Ley Lerdo

Ley Lerdo was an 1856 Mexican law that seized the Catholic Church’s vast haciendas and other property and put the lands up for sale. Its significance extended beyond the transfer of property: it formed part of a political rupture that stripped the Church of power and left Mexico and the Vatican without restored formal relations for more than a century.

Seizure and Sale of Church Lands

The law targeted church-owned haciendas and other lands, which the state seized and sold. In the novel’s account, this measure begins the long period of official Mexican anti-clericalism. It places control of extensive church property at the center of the conflict between the Mexican state and the Catholic Church.

Constitutional Conflict and Retaliation

The Mexican Constitution of 1857 further stripped the Church of power. The Vatican retaliated by excommunicating Mexicans who took the constitutional oath, turning a domestic constitutional settlement into an enduring confrontation over political authority and religious allegiance. The law and the constitution are distinct steps in that account: Ley Lerdo dispossessed the Church, while the constitution formalized its loss of power.

A Long, Uneasy Accommodation

Formal relations between Mexico and the Vatican were not resumed for over a century. The conflict did not eliminate the Church’s place in a country of faithful peasants, but it shaped the terms on which it could operate. Government harassment included a ban on clerical garb, alongside a grudging accommodation between the state and the Vatican. Ley Lerdo therefore stands at the beginning of a prolonged, unresolved settlement: the Church had lost property and political power, while neither side had wholly displaced the other.
