Yo Soy 132 is a Mexican protest movement centered around the democratisation of the country and it’s media. It began as opposition to the Institutional Revolutionary Party (PRI) candidate Enrique Peña Nieto and the Mexican media’s alledgedly biased coverage of the 2012 general election. The name Yo Soy 132, Spanish for “I Am 132“, originated in an expression of solidarity with the protest’s initiators.

On May 11, 2012, Peña Nieto held a campaign event at the University. Most of the attendees questioned and strongly expressed their opposition to the candidate. Their protest was centered around the 2006 Atenco incident, in which then-governor Peña Nieto called in the state police to break up a protest by local residents. Two protesters were killed, however, during the news conference, Peña Nieto defended his decision to use force in order to prevent an alleged greater evil. His answer inflamed the students, who started to chant the motto “Atenco is not forgotten”.
After the event, prominent media outlets and PRI politicians dismissed the attendees’ reaction, saying that they had been “smuggled in” by contending parties, and were not really students. In response, 131 students who had attended the event posted a video on YouTube showing their student IDs and expressing discontent with the media reporting of the event. When people began expressing solidarity with the students by tweeting “I’m the 132nd student”, the name “yo soy 132” was coined.

The movement successfully demanded that the second presidential debate be broadcast nationally. It also proposed a third debate organized by members of the Yo Soy 132 movement that was held without the presence of Enrique Peña Nieto, the candidate for the PRI, who rejected the invitation and said it lacked conditions of impartiality.

More recently, the movement has led massive student protests throughout the country.
