solidarity in Culture


A labor union in Poland, independent of the government and of the Polish Communist party, that grew to a membership of several million in the early 1980s. Led by Lech Walesa, Solidarity pushed for many reforms and played a major part in the ouster of communism in Poland and its replacement by a multiparty, democratic government. The movement's influence began to decline in the 1990s.
