The first agreement was signed in Szczecin on 30 August. The communist authorities accepted the strikers` demands, including the formation of trade unions. On the same day, the Central Committee of the Communist Party approved the signing of agreements with protesters in Szczecin and Gdansk. The last demand blocking the agreement was for the release of political prisoners, a point that the Communist Party accepted at the last moment. The best-known agreement was signed in Gdansk on 31 August by Lech Wałęsa and Deputy Prime Minister Mieczysław Jagielski. The communist regime allowed the creation of new independent trade unions, introduced the right to strike, accepted the construction of the Memorial to the Victims in December 1970, the broadcasting of Sunday Masses by Polish radio and the limitation of censorship. Trade unionists recognized the leading role of the Communist Party in the state. On 10 November 1980, the Supreme Court registered the Independent Autonomous Union « Solidarity ». Soon after, nearly 10 million people joined the union. The organization was established in all enterprises and factories, with the exception of the Polish army and the citizen militia. « Solidarity » was the first independent legal organization authorized to operate behind the Iron Curtain after World War II. He survived 16 months until the introduction of martial law in December 1981, when he was suspended and finally made illegal in 1982. The period when it was a legal union is often referred to as the « Carnival of Freedom » or the « Carnival of Solidarity » and paved the way for the Round Table agreements and the first partially free elections in 1989 and, consequently, the collapse of the Soviet Union in 1991.
