Solidarity (Polish: Solidarność, pronounced [sɔliˈdarnɔɕt͡ɕ] (audio speaker iconlisten); full name: Independent Self-governing Trade Union "Solidarity" – Niezależny Samorządny Związek Zawodowy "Solidarność" [ɲezaˈlɛʐnɨ samɔˈʐɔndnɨ ˈzvjɔ̃zɛk zavɔˈdɔvɨ sɔliˈdarnɔɕt͡ɕ]) is a Polish trade union that began on 17 September 1980 at the Gdańsk Shipyard under the leadership of Lech Wałęsa. It was the first trade union in a Warsaw Pact country that was not controlled by the Communist Party. It had 10 million members which was one in three of the total working-age population of Poland. Solidarity helped bring free elections to Poland. These elections were important as the country moved away from Communism.
