A report on Revolutions of 1989 and History of Poland (1945–1989)

Solidarity's leader Lech Wałęsa was awarded the Nobel Peace Prize in 1983 and the union is widely recognised as having played a central role in the Historyend of Communist rule in Poland.

Solidarity won 99 of the 100 Senate seats and all 161 contestable seats in the Sejm—a victory that also triggered a chain reaction across the Soviet Union's satellite states, leading to almost entirely peaceful anti-Communist revolutions in Central and Eastern Europe known as the Revolutions of 1989 (Jesień Ludów or Wiosna Obywatelów), which ended in the overthrow of each Moscow-imposed regime, and ultimately to the dissolution of the Soviet Union in the early 1990s.

During the revolutions of 1989 in Central and Eastern Europe, Jaruzelski supported the change of government for the benefit of the country and resigned after the Polish Round Table Agreement, which led to multi-party elections in Poland.

This question, as well as many other facts about Poland in the years 1945–1989, are presently under the investigation of government historians at the Instytut Pamięci Narodowej (IPN), whose publications reveal facts from the Communist-era archives.

Not all parliamentary seats were contested, but the resounding victory of the Solidarity opposition in the freely contested races paved the way to the end of communist rule in Poland.

On the international level, this election is seen as one of the major milestones in the fall of communism ("Autumn of Nations") in Central and Eastern Europe.

In addition to emigration restrictions, civil society, defined as a domain of political action outside the party's state control, was not allowed to firmly take root, with the possible exception of Poland in the 1980s.

Unlike previous Soviet leaders in 1953, 1956 and 1968, Gorbachev refused to use force to end the 1989 Revolutions against Marxist–Leninist rule in Eastern Europe.

The Pact began to unravel with the spread of the Revolutions of 1989 through the Eastern Bloc, beginning with the Solidarity movement in Poland, its electoral success in June 1989 and the Pan-European Picnic in August 1989.

From 1989 to 1991, Communist governments were overthrown in Albania, Poland, Hungary, Czechoslovakia, East Germany, Romania, Bulgaria, Yugoslavia, and the Soviet Union.

In the wake of anti-communist movements in 1989, notably through the emergence and contributions of the Solidarity movement, the communist government was dissolved and Poland re-established itself as a democratic republic.

It is considered to have contributed greatly to the Fall of Communism.

In his speech he talked about the "thick line" (Gruba kreska) which would separate his government from the Communist past By the end of August 1989, a Solidarity-led coalition government had been formed.
