Solidarity: "Solidarity was the first non-communist party-controlled trade union in a Warsaw Pact country. In the 1980s it constituted a broad anti-bureaucratic social movement. The government attempted to destroy the union during the period of martial law in the early 1980s and several years of political repression, but in the end it was forced to start negotiating with the union.
The Round Table Talks between the government and the Solidarity-led opposition led to semi-free elections in 1989. By the end of August a Solidarity-led coalition government was formed and in December 1990 Wałęsa was elected President of Poland. Since then it has become a more traditional, liberal trade union."
