President of Mexico Porfirio Díaz and the revolutionary Francisco Madero sign the Treaty of Ciudad Juárez to put an end to the fighting between the forces of both men, concluding the initial phase of the Mexican Revolution.

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.

José de la Cruz Porfirio Díaz Mori was a Mexican general and politician who was the dictator of Mexico from 1876 until his overthrow in 1911, seizing power in a military coup. He served on three separate occasions as President of Mexico, a total of over 30 years, this period is known as the Porfiriato and has been called a de facto dictatorship. Díaz’s time in office is the longest of any Mexican ruler.

Francisco Ignacio Madero González was a Mexican businessman, revolutionary, writer and statesman, who served as the 37th president of Mexico from 1911 until he was deposed in a coup d'état in February 1913 and assassinated. He came to prominence as an advocate for democracy and as an opponent of President and dictator Porfirio Díaz. After Díaz claimed to have won the fraudulent election of 1910 despite promising a return to democracy, Madero started the Mexican Revolution to oust Díaz. The Mexican revolution would continue until 1920, well after Madero and Díaz's deaths, with hundreds of thousands dead.
