Porfirio Díaz rebels against the reelection of President Sebastián Lerdo de Tejada, issues a plan of “effective suffrage and no reelection,” and seizes the presidency.

Except for the period of Manuel González’s presidency (1880-1884), Porfirio Díaz rules Mexico as president, but effectively as dictator.
