What did lech walesa a do to win more freedom for poles?

Lech Wałęsa co-founded the Solidarity movement in 1980, which was the first independent trade union in the Eastern Bloc. Through peaceful protests, strikes, and negotiations, he mobilized millions of workers to demand greater political freedom and economic reforms from the communist government in Poland. His leadership and advocacy for human rights played a crucial role in weakening the regime, ultimately leading to the Round Table Talks in 1989, which resulted in partially free elections and the establishment of a democratic government. Wałęsa's efforts earned him international recognition, including the Nobel Peace Prize in 1983.
