The Plan of San Luis Potosi

In September 1910, Porfirio Díaz, Mexico’s longtime president, staged the Fiestas del Centenario, or Centennial Festivals, to mark the hundredth anniversary of Mexico’s independence from Spain. Designed to showcase Mexico’s development into a modern nation, the celebrations were held amid widespread social unrest.

Only a few months later the revolutionary leader Francisco Madero issued his “Plan of San Luis Potosí”, challenging Díaz’s thirty-year virtual dictatorship and calling for countrywide insurrection to begin on November 20, 1910.
This date is now considered to be the start of the Mexican Revolution.
