After the war, under the Polish People's Republic, the intellectual and academic community of Kraków was put under total political control.
The universities were soon deprived of printing rights and autonomy.63 The Stalinist government ordered the construction of the country's largest steel mill in the newly created suburb of Nowa Huta.64 The creation of the giant Lenin Steelworks (now Sendzimir Steelworks owned by Mittal) sealed Kraków's transformation from a university city to an industrial centre.65 The new working class, drawn by the industrialisation of Kraków, contributed to rapid population growth. In an effort that spanned two decades, Karol Wojtyła, cardinal archbishop of Kraków, successfully lobbied for permission to build the first churches in the new industrial suburbs.6566 In 1978, Wojtyła was elevated to the papacy as John Paul II, the first non-Italian pope in 455 years.In the same year, UNESCO placed Kraków Old Town on the first-ever list of World Heritage Sites.
