Mariano Otero y Mestas was born on February 4, 1817 in Guadalajara.
He studied law at the Jalisco's Science Institute and completed his studies as a lawyer at the National University of Guadalajara, now University of Guadalajara.
He was a professor at the university and also practiced law.
His political philosophy led him to support the "Plan Jalisco" in 1841, which consisted in denying Anastasio Bustamente as Mexico's president.
In December of the same year, he was elected as Jalisco’s delegate in Congress.
His work consists on publications and essays on social and political matters inspired by "Plan Jalisco."
His goal to end centralist ideas led him to be co-founder and columnist of the "El Siglo Diez y Nueve" newspaper, a platform where he could share his perspectives.
By the end of 1843, during the North American invasion, Huejotzingo's people wanted to annul Congress. Otero remained firm on his stance and was a prisoner for a month.
This event inspired him to write the "Juicio de Amparo", which was included in the Mexican Constitution of 1857.
Mariano Otero was one of the four legislators who signed against the Treaty of Guadalupe-Hidalgo which handed over half of Mexico's territory.
He died in Mexico City at the age of 33, due to cholera. His remains have been relocated to the Rotonda de los Jaliscienses Ilustres (Honorable Citizens of Jalisco's roundabout).
One of the most important avenues of the city bears his name today; you can see the Niños Héroes Monument on this avenue.
