1982 demonstrations in Poland cities. On December 13, 1981, the Communist government of Poland under general Wojciech Jaruzelski crushed the opposition, introducing martial law. The main oppositional movement, Solidarity, was delegalized, and its key members were interned. However, by April 1982, Solidarity re-emerged, creating its underground body, the Temporary Coordinating Committee (known as "TKK" from the Polish name "Tymczasowa Komisja Koordynacyjna"), with delegates who had eluded arrests – Zbigniew Bujak from Warsaw, Bogdan Lis from Gdańsk, Władysław Frasyniuk from Wrocław, and Władysław Hardek from Kraków. At the beginning, the Committee opposed street demonstrations, drawing the so-called "Five times yes" appeal, which stipulated negotiations with
Wojciech Jaruzelski appearances. However, Wałęsa persuaded the Communists' two allied parties, the United People's Party (ZSL) and the Alliance of Democrats (SD), to break their alliance with the PZPR. Accepting that he would have to appoint a Solidarity member as prime minister, Jaruzelski then asked Wałęsa to select three candidates, one of whom he would ask to form a government. Ultimately, Tadeusz Mazowiecki, who had helped organize the roundtable talks, was selected as first non-Communist prime minister of an Eastern Bloc country in four decades. Jaruzelski resigned as president in 1990. He was succeeded by Wałęsa, who had won the presidential election
