Throughout the 1980s, these ideas increased in popularity among college-educated Chinese. In response to growing corruption, economic dislocation and the sense that reforms in the Soviet Union and Eastern Europe were leaving China behind, the Tiananmen Square protests erupted in 1989. These protests were put down by government troops on June 4, 1989. In response, a number of pro-democracy organizations were formed by overseas Chinese student activists, and there was considerable sympathy for the movement among Westerners, who formed the China Support Network (CSN).
