The Ten Tragic Days ("La Decena Tragica") was a series of events that took place in Mexico City between February 9 and February 19, 1913, during the Mexican Revolution. They culminated in a coup d'état and the assassination of President Francisco I. Madero and his vice president, José María Pino Suárez.

Francisco Madero was elected President of Mexico in October 1911.

Within a few months, Madero began to lose support and come under criticism. Though Madero came from a conservative wealthy background, the conservatives never forgave him for driving Porfirio Díaz out of office. Madero’s supporters became disillusioned when he refused to implement their plans such as the breakup of the large estates. Madero, at the end of his first year in the presidency, was in a bad way. The country was to a considerable extent unsettled, the treasury was depleted, and Madero’s staff and supports were only slightly less audacious than the hated Cientificos of the Porfirio Díaz’s rule. It was the prevailing wisdom that a popular revolution would occur soon.^{[citation needed]}
