Poland bans Solidarity and all other trade unions.
Solidarity (Polish: *Solidarno??*) was a Polish trade union and social movement that played a decisive role in weakening communist rule in Poland and, ultimately, across Eastern Europe. It emerged in August 1980 during a wave of strikes caused by rising food prices, low wages, poor working conditions, and widespread dissatisfaction with Poland’s communist government. The most important strike took place at the Lenin Shipyard in Gda?sk, where workers led by electrician **Lech Wa??sa** demanded not only better economic conditions but also the right to establish independent trade unions. After weeks of protests, the government signed the **Gda?sk Agreement** on 31 August 1980, allowing workers to organize independently of the Communist Party. Solidarity was formally established soon afterward and became the first independent trade union permitted in a Soviet-bloc country.
Solidarity rapidly developed into something much larger than a conventional trade union. Within months, it claimed around **10 million members**, representing a substantial proportion of Poland’s working-age population. Its supporters included industrial workers, farmers, intellectuals, students, and members of the Catholic Church. Although Solidarity initially concentrated on workers’ rights and economic reform, it increasingly demanded freedom of expression, political accountability, and greater independence from communist control. The movement benefited from the moral support of the Polish-born **Pope John Paul II**, whose visits to Poland encouraged opposition to the regime. Solidarity’s extraordinary growth alarmed both the Polish communist leadership and the Soviet Union, which feared that similar movements might spread throughout Eastern Europe.
The government responded dramatically on **13 December 1981**, when General **Wojciech Jaruzelski** imposed martial law. Solidarity was suspended, thousands of activists were arrested or interned, demonstrations were violently suppressed, and the organization was formally outlawed in 1982. Wa??sa was detained for nearly a year, but Solidarity survived underground through illegal publications, secret meetings, strikes, and support networks. International pressure also helped sustain the movement, while Poland’s continuing economic difficulties weakened the communist government. Wa??sa’s international stature increased when he received the **Nobel Peace Prize in 1983**, although he did not travel to Norway to accept it personally because he feared Polish authorities might prevent him from returning home.
By the late 1980s, economic crisis and renewed strikes convinced the government that repression alone could no longer maintain stability. In 1989, communist officials entered negotiations with Solidarity during the **Round Table Talks**, leading to the legalization of the union and partially free parliamentary elections in June. Solidarity-backed candidates achieved an overwhelming victory, and in August **Tadeusz Mazowiecki**, a Solidarity adviser, became Poland’s first non-communist prime minister since the establishment of communist rule after World War II. These events helped trigger the collapse of communist governments elsewhere in Eastern Europe during 1989. Solidarity continued as a trade union after Poland became a democracy, while Wa??sa served as president from 1990 to 1995. The movement remains one of the most important examples of organized workers and civil society peacefully challenging an authoritarian political system.
