Solidarity · Full chronicle and history

After the fall of the Berlin Wall, Poland's Solidarity trade union took power, Mazowiecki became Poland's first democratically elected prime minister, and he convened a conference on experience exchange among anti-communist alliances, which Yu Maochun attended.

In 1980, Poland founded the independent trade union Solidarity during the communist era. The union later became the impetus for designing Polish society beyond the government in the post-communist period, enabling a relatively smooth transition after the fall of communism in Poland.
