Student-led uprisings in October 1973 led to a new vision of liberating the country from military government for a short period. The media received more freedom to criticize politicians and governments, while revolutionary and socialist movements became more apparent. The new civilian government officially shut US bases amid the fear of communist victory in the Indochinese countries in 1975. In 1976, Admiral Sa-ngad Chaloryu, the armed forces commander, staged a massacre and coup that brought hard-line anti-communists to power and reversed these reforms.
