Bases Orgánicas

Bases Orgánicas (English: Organic Bases) was the name given to the constitution of Mexico which came into effect in 1843. It was the second and final constitution attempted during the Centralist Republic of Mexico, after the Siete Leyes.

National instability had resulted in a coup which overthrew the presidency of Anastasio Bustamante at the end of 1841. The coup plotters led by Santa Anna had proclaimed the need for a new constitution, and held elections for a new constitutional congress. The newly elected congress however was not to the government's liking and it was subsequently dissolved in a self-coup at the end of 1842. A new government appointed a Council (Junta) of Notables that produced a new constitution on 12 June 1843.
