Jacek Jan Kuroń (; 3 March 1934 – 17 June 2004) was a Polish social activist, politician, and one of the most prominent democratic leaders of the opposition in the People's Republic of Poland (PRL). Kuroń played a pivotal role in challenging Communist rule and advocating for democratic reforms during the latter half of the 20th century. After the PRL fell in 1989, Kuroń served as Minister of Labour and Social Policy twice in post-communist Poland, from 1989 to 1990 in the government of Tadeusz Mazowiecki and from 1992 to 1993 in the government of Hanna Suchocka. As an educator and political theorist, he is also known for co-authoring the "Open Letter to the Party".

Initially an idealistic communist in his youth, he first rose to prominence as a revisionist Marxist critic of the PRL and Władysław Gomułka following the events of Polish October. In 1965, together with Karol Modzelewski, he co-wrote the "Open Letter to the Party", which used Marxist theory to argue that a new bureaucratic class had formed under Gomułka which had betrayed the workers, and that the only solution was for a revolution in Poland. His political activities after made him a frequent target of the Security Service (SB), and he spent multiple years in prison from 1965 to 1967 and again from 1969 to 1971. Following the brutal suppression of protests during the December 1970 protests in Poland by Gomułka, Kuroń abandoned Marxism and embraced a philosophy influenced by Christian personalism, although he remained a lifelong atheist. Following these events, he became a key organizer of the Workers' Defence Committee (KOR) in 1976, which provided aid to persecuted workers and laid the groundwork for the subsequent Solidarity movement.

Following the formation of the Solidarity trade union in 1980, he played a major role in supporting it. Although relations between Kuroń and its leader Lech Wałęsa soon started to break down, he still publicly supported the movement and helped to negotiate August Agreements which legalized independent trade unions. After the start of martial law in 1981, he was arrested again and served another prison sentence from 1981 to 1984. After his release, Kuroń participated in the Polish Round Table Agreement as a member of Solidarity's team, which led to Poland's transition to democracy and he was subsequently elected to the Sejm in the first semi-free elections in 1989. After being chosen as Minister of Labour in 1989, he oversaw the implementation of the economic plan of shock therapy while attempting to provide unemployment benefits for the millions that soon lost employment that became known as "kuroniówka." During this time, many of his policies such as his advocacy for rapid privatization and his role in designing a transition that allowed Communist elites from the PRL to exit power without prosecution, were controversial and were decisions he later stated he regretted. In 1995, he ran for president, but was ultimately unsuccessful, placing third, garnering 9.22% of the first-round votes.

Kuroń's political philosophy after his time as minister started to evolve to focus on civic education and minorities. In the Sejm, he represented the Freedom Union starting in 1994 and became Chairman of the Commission for National and Ethnic Minorities, a role in which he adovcated for Roma, Ukrainian, and Jewish communities. As he became increasingly critical of neoliberalism and social inequality, he founded Poland's first food bank after the collapse of the PRL in 1994 called the SOS Foundation and established the Jan Józef Lipski Common University in 2000 to promote civic education, especially in rural areas. He received numerous honours during his lifetime, including the Order of the White Eagle, Poland's highest award, and international awards from France, Germany, Lithuania, the Czech Republic, and Ukraine. Kuroń died on 17 June 2004 after years of declining health since the 1990s. Since his death, he has had numerous streets, squares, and institutions named after him in Poland and in his hometown of Lviv.

Early life Kuroń was born on 3 March 1934 in Lwów, which was then part of the Second Polish Republic (now Lviv, Ukraine). He was the son of Henryk Kuroń (1905-1982) and Wanda née Rudeńska (1911-1978). His mother, Wanda, graduated with a law degree from Jagiellonian University. On his paternal side, his father, Henryk, was initially a miner from Zagłębie before graduating from Lwów Polytechnic and joining the Union of Independent Socialist Youth (PPS).

Describing his childhood, Kuroń said he grew up in a multi-ethnic environment of Poles, Ukrainians, Jews, and Armenians. He described his first political memory as attending the funeral of Władysław Kozak, a worker killed by the police in Lwów in 1936. During the start of World War II, he described witnessing Polish men throwing stones at Jews, due to what he called a social climate of complicity, which would be a turning point in his life, as he stated he carried a moral responsibility for not acting.

In the spring of 1944, he and his family moved to modern-day Poland to the Podkarpackie Voivodeship. On 12 January 1947, after having previously moved to Kraków after Podkarpackie during the war, his family moved into the residential building on Wilsona Square in Warsaw with an address of 27 Mickiewicza Street, a building he lived at for his whole life. Two years later in 1949, he became a member of the Communist Association of the Polish Youth (ZMP). He described his path into communism as a rebellion against his family's socialist tradition - his father had joined the PPS - a rebellion spurred on after he read Marxist and Leninist texts, which he believed were the "key to unlock the world". He described himself as more of an ideological communist, seeing his ZMP membership as a way to live out the ideals of sovereignty, freedom, and equality. He was soon after briefly the chairman of the School Board of the ZMP in Poniatówka, but was removed from this position soon after at the start of the year 1950 at the request of the school administration, mostly due to his poor academic results and for showing teachers his writings.

In 1952, he graduated from high school and received his diploma. Starting in 1952, he worked as a full-time employee in the capital scout section, which were affiliated with the Association of the Polish Youth. He also joined the Polish United Workers' Party (PZPR). The following year, in March, he became the Chairman of the University Board of the ZMP at the Warsaw University of Technology. However, he did not last in this position for long as in November 1953, he was expelled from the ZMP apparatus and from the PZPR. The reason for this was him criticizing the ideological concept of the ZMP, which he refused to retract, and so he was removed from the list of members of the ZMP.

Early social and political activities

In the autumn of 1953, he began his studies at the State Higher School of Pedagogy, majoring in Russian studies in Warsaw, and upon the dissolution of the school in 1955, he started attending the University of Warsaw, studying history. In 1955 the Crooked Circle Club was also established, which was a discussion club for the young intelligentsia. The press organ of the club was "Nowy Nurt". Prior to this, Kuroń had been part of a young circle of Marxists who met at the university library of the State Higher School of Pedagogy starting in 1953 who concluded that collectivization and the war against the peasants had "destroyed the revolution" by handing power to bureaucracy. Jacek Kuroń and Karol Modzelewski were among the most prominent members of the club. During this time, he also became part of the intellectual milieu that published the weekly newspaper of Po Prostu, which was a forum for the "October left". In June 1956 he was readmitted into the PZPR after he became active in politics at the university, organizing rallies in what he later called the "young guard of the proletarian masses", and tried to unite the students and workers through the ZMS. During the summer of 1955, Kuroń led the scouts in a summer camp in Wolin. While taking a trip to the Union of Lublin Square, some of the participants of the camp, under the permission of Kuroń, bathed in the Vistula river. However, three of the participants got carried away by the currents of the Vistula and were killed. He was then arrested on 30 August and charged with the manslaughter of the three children, and ordered to stand trial. In April 1956, however, the proceedings were discontinued under amnesty, although the mother of one of the children filed a separate civil lawsuit for compensation against him. Following this, he was banned from working directly with young people as a scout leader, although until 1964 he was permitted to remain involved in the scouting movement in other capacities.

During Polish October, he attended the mass protests, particularly the one on 24 October 1956 in Warsaw, where over 200,000 people greeted Władysław Gomułka. After this, he started writing and distributing texts against the PZPR's Natolinians, who were against liberalization, alongside writing against the PAX Association which he associated with fascism. He distributed these in factories and schools. During this time, he aligned himself with the "October left", who opposed Stalinism while also supporting Marxist ideals, marking his shift to a more radical and critical left position. He considered the "October left" to be the more authentic heirs of the Polish October, and the only ones committed to a true revolution and workers' empowerment. In December 1956, after the events of Polish October, the Łódź congress was held, which reestablished the Polish Scouting and Guiding Association (now renamed to ZHP from ZMP). During the congress, he was an active participant, specifically on whether scouting should be political or religious, and how the organization should be rebuilt. He championed socialism as the spirit of the new organization, arguing that socialist ideology was essential for scouting. However, he soon grew disillusioned with the liberalization after the Polish October led by Gomułka, after seeing that the reforms were limited and deepened his revisionist stance. He saw Yugoslavia's system of worker self-governance and linked democracy to active participation in economic management as something that should be replicated in Poland. As he would later argue in the open letter, the "October left" had failed to create its own political program and supported the liberal wing of bureaucracy - that is, Gomułka's faction - which led to stabilization and crushed any revolution. He saw the Workers' Councils in Poland as a foundation of a new socialist democracy, but he accused the October left of not separating itself from technocrats or liberal bureaucrats, and thus losing its chance to lead the nation.

The following year, he co-founded the scouting association called the Walterowcy (named after Karol Świerczewski, who went by the callsign "Walter"). It was founded after he had graduated from the University of Warsaw in the Faculty of History. The educational concept of an athetistic socialist upbringing, as opposed to the traditional Catholic scouting tradition, was formulated by Kuroń which became the guiding ethos of the Walterowcy. He was mostly inspired by Anton Makarenko's The Pedagogical Poem and the ideas expressed there, as he wanted to build socialist consciousness through education. However, the troops only remained active for a short time: by 1961, the scouts had been disbanded after many members of the scouting group, including Kuroń, had criticized social and political conditions in Poland under Gomułka’s regime after they had rolled back some of the openness that had been present after the Polish October.
