The history of Solidarity (Polish: Solidarność, pronounced [sɔliˈdarnɔɕt͡ɕ] ), a Polish non-governmental trade union, began on August 14, 1980, at the Lenin Shipyards (now Gdańsk Shipyards) at its founding by Lech Wałęsa and others. In the early 1980s, it became the first independent labor union in a Soviet-bloc country. Solidarity gave rise to a broad, non-violent, anti-communist social movement that, at its height, claimed some 9.4 million members. It is considered to have contributed greatly to the fall of communism.
