The KPJ proclaimed shift from party monopolising power to the ideological leader of the society, decentralised its structure, and rebranded itself (and correspondingly its republican organisations) as the League of Communists of Yugoslavia ("Savez komunista Jugoslavije", SKJ) at its sixth congress held in Zagreb in 1952. The name was inspired by the 1847–1852 Communist League. The constitutional amendments, adopted in 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 in all subsequent Yugoslav constitutions.
