Lázaro Cárdenas, Mexican general and politician, 44th President of Mexico (born 1895)

Lázaro Cárdenas del Río was a Mexican army officer and politician who served as president of Mexico from 1934 to 1940. Previously, he served as a general in the Constitutional Army during the Mexican Revolution and as Governor of Michoacán and President of the Institutional Revolutionary Party. He later served as the Secretary of National Defence. During his presidency, which is considered the end of the Maximato, he implemented massive land reform programs, led the expropriation of the country's oil industry, and implemented many key social reforms.

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.
