The Zapatista uprising begins in Chiapas on January 1, 1994, the day NAFTA goes into effect, and Subcomandante Marcos becomes the icon of the rebellion. The efforts of peace commissioner Manuel Camacho Solís to deal with the crisis prove popular, putting Colosio's candidacy into doubt. On March 6, Colosio delivers a public address in Mexico City acknowledging Mexico's problems and pledging to reform the system and oppose authoritarianism, revitalizing his campaign.

Zedillo assumes the presidency on December 1, 1994, and is confronted with a devastating economic crisis. Marcos is "unmasked" as Rafael Sebastián Guillén in a failed effort to damage the Zapatistas' image. The special prosecutions continue for the murders of Colosio and Ruiz Massieu. Raúl Salinas is arrested and charged with Ruiz Massieu's murder, but is exonerated after spending ten years in prison. Zedillo's administration ends in a democratic transition to Vicente Fox of the opposition PAN in 2000.
