Background and detail

Background. The Second Federal Republic refers to the period after the fall of the unitary Centralist Republic in 1846. The Mexican–American War began in April 1846 during the presidency of Mariano Paredes. The restoration of the Constitution of 1824 marked the end of the Centralist era and the beginning of a new federalist phase in Mexican history.

Political Transition. José Mariano Salas served as provisional president in 1846. On August 22, he restored the Constitution of 1824, ending the Centralist Republic. Salas allowed the exiled Santa Anna to return, who embraced the liberal Constitution, thus restoring the federal system. Congress opened its sessions in December 1846, composed mostly of liberals.

Valentín Gómez Farías. Valentín Gómez Farías, a liberal politician, supported the return to the federalist system. He had previously led a failed revolt in 1840. In 1846, following the war's start, he was re-elected as president alongside Santa Anna, who had reconciled with him and supported federalism.
