After the 1910 revolution, the Mexican political system depended on tactics of repression, manipulation, and coercion to control the actions of the opposition. In 1968, the government was faced with a movement that could not be controlled by the same tactics. The student movement of 1968 represented a change in the political system where those who felt oppressed expressed their discontent, despite government repression. Luis Echeverria, the president from the student movement, faced political unrest and instability during his presidency; he instituted reforms considered “left-wing” in his day. Although Echeverria did this because he felt the need to reform the political party from within, the political climate that followed the student revolt inadvertently led to the beginning of the end of the PRI regime. The 1968 student movement began when police intervention after a clash between two rival high schools resulted in violence. Students began uniting to protest the unnecessary violence used by police, and police continued to disperse any student protests. Initially, the movement had no ideological basis; the cohesion of the movement was based on the violence they all experienced. Soon the movement began to develop its ideological unity. Protesters have focused on the upcoming Olympics, which will be held in Mexico, to persuade the government to comply with their demands. President Gustavo Díaz Ordaz began to question whether the government would be able to control the movement by the 1968 Olympics. The clash between the students and the government came to a head in Tlatelolco on October 2, 1968, two weeks before the Olympic Games. The students planned a peaceful demonstration, but the government...... middle of paper ...... strengthened cohesion; it began to develop factions within it. These “left” factions that developed within the party would be the ones that would ultimately bring about the downfall of the PRI regime.
