Gdansk Shipyard: The Gdansk Shipyard is where Solidarity originated. It was the birthplace of the movement and served as a gathering place for workers to protest against unfair labor conditions.
Martial Law: When Solidarity gained popularity, the Polish government declared martial law, which involved military control over civilians. This was done to suppress dissent and maintain control over the country.
Perestroika: Perestroika refers to Soviet leader Mikhail Gorbachev's policy of restructuring aimed at reforming socialism. It influenced democratic movements in Eastern Europe, including Solidarity, by encouraging political openness and economic reforms.
