In 1835, there was a drastic shift to the new Mexican Nation. The triumph of conservative forces in the elections unleashed a series of events that culminated on 23 October 1835, during the interim presidency of Miguel Barragán (the constitutional president was Antonio López de Santa Anna, but he was out of office), when the "Basis of Reorganization of the Mexican Nation" was approved, which ended the federal system and established a provisional centralist system. On 30 December 1836, interim president José Justo Corro issued the Seven Constitutional Laws, which replaced the Constitution. Secondary laws were approved on 24 May 1837.
