After the death of Joseph Stalin and the consequent process of de-Stalinization in the Soviet Union and allied states, socialist realism began to lose its popularity. Many Romanian and Western authors, their works previously banned, were "reconsidered" and published in critical editions. A new generation of writers, heralded by Nicolae Labiş but reaching fruition with Nichita Stănescu and Marin Sorescu, protested vehemently against ideological dogmatism and called for full artistic liberty. Styles and genres of literature, plastic arts and music began to loosen in the early 1960s, while still maintaining the core principles of Communism and adherence to Party policy. However, this trend came to an abrupt halt with the "July Theses" of 1971, after which General Secretary Ceauşescu began not only to repress dissidents such as Paul Goma and Mircea Dinescu, but also to promote his own personality cult. Manifestations of this era of reborn socialist realism could be found in painting, architecture (the Palace of the Parliament), writing (the poems of Corneliu Vadim Tudor) music (Adrian Păunescu's "Cenaclul Flacăra" events) and other areas. Socialist realism ended in Romania with the 1989 Revolution.
