The apogee of Bierut's cult, promoted by the authorities over a number of years, was the celebration of his sixtieth birthday on 18 April 1952. It included various industrial and other production or accomplishment commitments undertaken by institutions and individuals. The University of Wrocław and some state enterprises were named in his honor. The History Department of the party's Central Committee prepared a special book about Bierut and his life, while Polish poets, including some notable ones, generated a book of poems dedicated to the leader. Many postage stamps dedicated to Bierut were issued.
