Polish United Workers Party in the context of "1989 Polish legislative election"

Parliamentary elections were held in Poland on 4 June 1989 to elect members of the Sejm and the recreated Senate, with a second round on 18 June. They were the first free and fair elections in the country since the communist government abandoned its monopoly of power in April 1989 and the first elections in the Eastern Bloc that resulted in the communist government losing power.

Not all seats in the Sejm were allowed to be contested, but the resounding victory of the Solidarity opposition in the freely contested races (the rest of the Sejm seats and all of the Senate) paved the way to the end of communist rule in Poland. Solidarity won all of the freely contested seats in the Sejm, and all but one seat in the Senate, which was scored by a government-aligned nonpartisan candidate. Most crucially, the election served as evidence of widespread dissatisfaction with the government. In the aftermath of the election, Poland became the first country of the Eastern Bloc in which democratically elected representatives gained real power. Although the elections were not entirely democratic, they led to the formation of a non-communist government led by Tadeusz Mazowiecki and a peaceful transition to democracy in Poland and elsewhere in Central and Eastern Europe.
