Luis Echeverría, Mexican academic and politician, 50th President of Mexico (died 2022)

Luis Echeverría Álvarez was a Mexican lawyer, academic, and politician affiliated with the Institutional Revolutionary Party (PRI) who served as the 57th president of Mexico from 1970 to 1976. Previously, Echeverría was Secretary of the Interior from 1963 to 1969. He was the longest-lived president in Mexican history and the first to reach the age of 100.

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.
