Yugoslavia
Djilas, one of Tito's closest confidants, disagreed with the Brioni decisions. In a number of articles in the foreign press, he criticized the party leadership for stifling democratic intraparty debate. This criticism exceeded Tito's tolerance, and his former comrades dismissed Djilas from his posts and imprisoned him. In 1957 Djilas published The New Class, in which he described the emergence of a new communist ruling elite that enjoyed all the privileges of the old bourgeoisie. The book won him international notoriety and prolonged his jail term. Publication of Conversations with Stalin in 1962 earned him more fame and a second prison term. In 1963 Yugoslavia established new constitutions at the national and republican level, expanding the concept of self-management beyond the economic sphere into social activity. In 1974 the government enacted a new Constitution, the world's longest, which created new representative bodies and a complex system of checks and balances, designed to enhance party power and limit the influence of professional enterprise managers. In 1980 Yugoslavia entered a new era after the death of the most unifying leader the South Slavic nation had ever had.
