Ultimately, the KPJ accepted decentralisation and rebranded itself as the League of Communists of Yugoslavia ("Savez komunista Jugoslavije", SKJ) at its sixth congress held in Zagreb in 1952 to reflect the prevailing spirit. The constitutional amendments, adopted on 13 January 1953, were only the second step in a series of five constitutional reforms reflecting the social development of Communist-ruled Yugoslavia, but the principles introduced in 1953 were retained all the way to socialist Yugoslavia's final constitution adopted in 1974.
