It was general José Mariano Salas who, on August 5, 1846, announced the reestablishment of federalism, convening a constitutional congress that declared current the constitution of 1824, but still didn't consider Aguascalientes as a state. Subsequently, on May 18, 1847, amendments were approved to the Constitution of 1824, but neither granted to Aguascalientes the status of a state. That brought about a war between Aguascalientes and Zacatecas, and as a consequence Zacatecas would strengthen the partitions, now municipalities, of Cavillo and Rincón de Romos. In July 1848, Aguascalientes accepted the peaceful annexation to Zacatecas; but continued making efforts to separate through Miguel García Rojas. It was not until December 10, 1853, that López de Santa Anna, using his extraordinary powers, issued a decree declaring Aguascalientes a department, based on the decrees of December 30, 1836, and June 30, 1838, without ever referring to the one from March 23, 1835. Finally, in the project that would be the Constitution of 1857, that was presented on June 16, 1856, Aguascalientes was included as a state in Article 43; it was passed unanimously by the 79 deputies present, ensuring the establishment of the state of Aguascalientes on December 10, 1856. On September 16, 1857, on the strength of said constitution, Lic. Jesús Terán Peredo reclaimed his post as constitutional governor of the state.
