Student demonstrations had started in 1968 and grew in size and numbers in the early 1970s despite the continued ban on political meetings.

Shortly after, thousands of students held a protest at the Democracy Monument demanding the re-enrolment of the nine students. The government ordered the universities to shut, but shortly afterwards allowed the students to be re-enrolled.

In October another 13 students were arrested on charges of conspiracy to overthrow the government. This time the student protesters were joined by workers, businessmen, and other ordinary citizens. The demonstrations swelled to several hundred thousand and the issue broadened from the release of the arrested students to demands for a new constitution and the replacement of the current government.

Leaders of the demonstrations, among them Seksan Prasertkul, called off the march in accordance with the wishes of the king who was publicly against the democracy movement. In a speech to graduating students, he criticised the pro-democracy movement by telling students to concentrate on their studies and leave politics to their elders [military government]. 1973 Uprising brought about the most free era in Thai recent history, called "Age when democracy blossom" and "Democratic experiment," which ended in Thammasat University massacre and a coup on 6 October 1976.
