Longtan Coup

The 1962 Tsengian coup d'etat, popularly known as the Longtan Coup (Chinese: 龍潭政變; pinyin: Lóngtán Zhèngbiàn), the March 11 Incident or Longtan Incident, was a major event in the history of the Tseng Republic. In the morning of March 11, 1962, armed people dressed in black entered the Longtan Complex located in the resort town of Longtan, Tseng, and killed President Jack Lin. It was later revealed that the people in black were members of the illegal Communist Party of Tseng and the far-left militant group Red Saviors. After Lin was murdered, the assassins left the complex and drove to Tseng City, where they informed Frederik Bao of the incident. At 9am, Bao proclaimed himself as President of Tseng, which caused polarizing reactions. There was outrage and celebrations, and later that day, the first attacks of the Luanzheng Era occured as the country was now divided.

Background
On July 13, 1958, President Yong Ming-chun signed into law Bill 643, also known as the "Law for the Defense Against Communism and Far-Left Ideology", which criminalized far-left ideologies such as communism and anarchism. Therefore, many communist sympathizers were attacked and arrested by the Tsengian police, and the only left-wing party allowed to exist was the Tsengian Socialist Union, which had become centre-left over the years and not representative of the Tsengian left-wing.

Many far-left Tsengians, such as Frederik Bao or Harold Kim, objected to the law, and began plans to fight back. This involved radicalizing an increasingly restless population who were getting tired of economic stagnation under Yong, and furthered following the inauguration of liberal Jack Lin 9 days later. Lin refused to repeal Bill 643, afraid that it would "destabilize" the nation, which angered Bao.
