Hoxha's political influence in the Yugoslav Communist Party grew during the 1960s, especially after the removal from the upper echelons of the party of Serb hardliner Aleksandar Ranković by Josip Broz Tito. As interior minister, Ranković had pursued a notorious policy of repression against Albanians, which was later criticized by the party. Hoxha led efforts to advance Kosovo's constitutional status in a series of constitutional reforms that took place in Yugoslavia. The efforts were consecrated by the Yugoslav constitution of 1974, which granted Kosovo an equal republican status in all but name.
