Nicolás Bravo, Mexican soldier and politician, 11th President of Mexico (died 1854)

Nicolás Bravo Rueda was a Mexican soldier and politician who served as interim President of Mexico three times, in 1839, 1842, and 1846. Previously, he fought in the Mexican War of Independence, and served as Mexico's first Vice President under President Guadalupe Victoria from 1824 until 1827, when he attempted to overthrow Victoria. He was also the fourth vice president under President Mariano Paredes in 1846, and served in the Mexican–American War.

The president of Mexico, officially the president of the United Mexican States, is the head of state and head of government of Mexico. Under the Constitution of Mexico, the president heads the executive branch of the federal government and is the commander in chief of the Mexican Armed Forces. The office, which was first established by the federal Constitution of 1824, is currently held by Claudia Sheinbaum, who was sworn in on October 1, 2024. The office of the president is considered to be revolutionary, in the sense that the powers of office are derived from the Revolutionary Constitution of 1917. Another legacy of the Mexican Revolution is the Constitution's ban on re-election. Mexican presidents are limited to a single six-year term, called a sexenio. No one who has held the post, even on a caretaker basis, is allowed to run or serve again. The constitution and the office of the president closely follow the presidential system of government.
