Congress of San Luis Potosí

The Congress of the State of San Luis Potosí is the legislative branch of the state government of San Luis Potosí, Mexico. It is composed of 27 deputies, of whom 15 are elected by relative majority in single-member districts and 12 by proportional representation. The congress meets in the President Juarez Building, located in the Historic Center of San Luis Potosí^[1]

With the promulgation of the Federal Constitution of 1857, the states of the Mexican Republic were required to establish their own legislatures. In San Luis Potosí, Governor Eulalio Degollado convened a constituent congress, which was installed on 5 July 1857. This first constituent congress was dissolved following the proclamation of the Plan of Tacubaya in December of that year, which rejected the new federal constitution and abolished state congresses, triggering the Reform War.^[2]

In 1860, Liberal governor Sóstenes Escandón convened another constituent congress, which was suspended due to the declaration of a state of siege amid the ongoing conflict. The constituent legislature was finally established on 14 April 1861. It completed the drafting of the Constitution of San Luis Potosí on 13 July, which was promulgated on 27 July 1861. Both the constitution and the congress were abolished during the Second Mexican Empire (1863–1867). Following the fall of the empire, the state constitution and congress were reinstated.^{[2] [3]}

After the promulgation of the Mexican Constitution of 1917, the XXV Legislature acted as a constituent body to reform the state constitution in line with the new federal charter. Between 1938 and 1943, the federal government twice decreed the disappearance of powers in the state, causing the congress to suspend its functions on both occasions.^{[2] [4]}
