The Plan of San Luis de Potosí was the document that triggered the collapse of the Diaz regime in Mexico and called for a revolution in favor of democracy. The plan was written and published in Texas by a group of exiles led by Francisco Madero, a political opponent to Dictator Porfirio Diaz that was jailed when his popularity threatened the arranged triumph of the old leader in the 1910 presidential election.

The Plan asked the Mexican people to rise in arms on November 20, 1910, but the first action occurred two days earlier, when Aquiles Serdán was found to be part of Madero's revolution in Puebla state and was forced to an early fight in his home, helped by his family. Most of them died. After that, the Mexican Revolution broke in November the 20th of 1910 against the political,commercial and social policies of the regime, taking the effective suffrage and non re-election as a banner. Since the revolution ended this has been the motto of the Mexican state.

The document itself has passed as an important historic symbol for the current Mexican State that owes, in great part, its own existence in the collapse of the old regime and the instauration of the PRI dominated Republic.
