Formosa Incident (Kaohsiung Incident)
On December 10, 1979, Shih Ming-teh, Yao Chia-wen, and two to three hundred supporters held a rally at the Zhongshan Roundabout, which ended in clashes with riot police and forced dispersal. In the aftermath, most leading figures of the tangwai opposition movement were arrested — the event known as the Formosa Incident.
