La Reforma

During La Reforma war, the city changed hands various times between Liberal and Conservative forces between 1858 and 1860. The most notable battle of that war here was when General José Iniesta attacked the town on 18 February 1859. In that same year, León even separated for a time from the rest of the state of Guanajuato.

In 1862, the bishopric of León was founded, separating the city of León and nine other municipalities such as Irapuato, Guanajuato and Dolores Hidalgo from the bishopric of Michoacán. Bishop Diez de Sollano opened the Conciliar Seminary in 1864. This bishop consecrated the Basilica Cathedral in 1866, even though it was not completed, giving the image of the Virgin of the Light a permanent home.
