Who worked to restore Polish freedom by founding solidarity?

Lech Wałęsa was a key figure in restoring Polish freedom by founding the Solidarity movement in 1980. As a shipyard worker, he helped organize strikes and protests against the communist regime, advocating for workers' rights and democratic reforms. Solidarity became a powerful force in challenging the Soviet-backed government, ultimately leading to significant political changes in Poland and inspiring similar movements across Eastern Europe. Wałęsa later became the first democratically elected president of Poland after the fall of communism.
