20. Polish Solidarity Movement
The Solidarity movement in Poland began as a trade union in the Gdańsk shipyards, blending labor activism with daring underground opposition to communist rule. Led by Lech Wałęsa, Solidarity’s peaceful resistance sparked a wave of democratic change, ultimately toppling Poland’s communist regime in 1989. Their triumph inspired similar movements across Eastern Europe, hastening the end of the Cold War and shifting the region’s political landscape.
