The coin's reverse presents an image of Pope John Paul II holding a papal pastorate against the background of the crowd. An inscription above the crowd: SOLIDARITY, being a reproduction of the NSZZ "Solidarity" graphic symbol, in red and various shades of grey.  In 1988, strikes took place all over the country. One of the main demands was the re-legalisation of "Solidarity". On the thirty-first of August, Lech Wałęsa met with General Kiszczak. After the meeting, the leader of the opposition called for a halt to the strikes, and soon more meetings with representatives of the authorities took place. On 18 December, a Citizens' Committee was set up under the chairmanship of the Solidarity Trade Union, in which the supporters of compromise solutions prevailed. At the turn of 1988 and '89, the 10th Plenum of the Central Committee of the Polish United Workers' Party (PZPR) was held, during which party activists adopted the concept of an agreement with 'Solidarity'. From 6 February to 5 April 1989, the so-called Round Table was held. During these deliberations, both parties agreed, among other things, to change the electoral law, change the competences of the President and create a Senate. In addition, it was decided to establish the famous parity that was to apply in the elections to the Sejm. Although as many as 65% of the seats in the Sejm were to be given to representatives of the PZPR, ZSL, SD, the remaining 35% could be sought by opposition and non-partisan candidates. It was quite a revolution, but it was to be even greater in the Senate elections, which were to be completely free. On 7 April, changes were made to the law, as well as amendments to the constitution. On 17 April, the Supreme Court re-registered 'Solidarity'. The election campaign, unprecedented in the history of post-war Poland, began. The posters showed the recent enemy of the People's Republic of Poland, Lech Wałęsa, who supported the opposition candidates. The then established Gazeta Wyborcza daily presented pictures of Wałęsa with candidates, among them were candidates for the Sejm, among others: Among them were: Jan Maria Rokita, Adam Michnik, Jacek Kuroń, Jan Lityński or Bronisław Geremek and to the Senate, including Jarosław and Lech Kaczyński, Bogdan Lis, Anna Radziwiłł, Zbigniew Romaszewski, Gustaw Holoubek or Andrzej Wajda. They all called them the 'Lech team'. In the air one could sense hope and mobilisation on the part of the candidates, who, without the social and technical tricks and marketing procedures known today, were calling the public to vote. The posters displayed slogans such as 'Don't sleep because they'll vote for you' or 'First time you can choose - choose Solidarity'. Solidarity was helped by so many volunteers that in many cities, the then government resigned from sealing posters of the opposition. The revolution also took place in the public media, which all electoral committees could use. Despite the fact that representatives of the ruling camp were still the most frequent guests on television, there were programmes such as that of Jacek Fedorowicz, which openly mocked the ruling party. The Communist authorities were helpless. The best proof of this was the final outcome of the elections, which was the absolute success of Solidarity. The opposition brought into the Seym all the Members of Parliament that it could have brought in as part of its parity. The Senate elections were only a confirmation of the victory of the opposition, which won 99 out of 100 senatorial seats, without any representative of the authorities getting into the Senate. The only Senator outside the Solidarity camp was the non-attached Henryk Stokłosa. The failure surprised the authorities, and the success surprised ... Solidarność, which before the elections timidly counted on several dozen seats. On 23 June, MEPs and senators elected from Solidarity's letters formed the Civic Parliamentary Club, headed by Bronisław Geremek. The communists' total electoral defeat prevented them from forming a government, which is why on 24 August 1989 the coalition government was headed by Tadeusz Mazowiecki, the first prime minister of free Poland after the war.
