was electing 15 members of the presidency and one president for a 4-year term, and later 2-year term. The new constitution practically suspended Serbia's authority over the provinces. After the new constitution was adopted, Dragoslav Marković, then President of Serbia ordered a secret study on this issue. In January 1975, the Presidency of the Socialist Republic of Serbia requested a revision of constitutional solutions with explanation that the constitution divided the republic into three parts, thus preventing Serbia from exercising its "historic right to a nation state in the Yugoslav federation". Furthermore, the study Marković requested was completed in 1977 and was named The Blue Book. Although there were differing opinions in the state leadership on the position of the provinces – for example, Edvard Kardelj supported the demands of Serbian leaders – the result of the arbitration was the conclusion that the position of the provinces within Serbia should not be changed. The Federal leadership, led by Tito, believed that the constitutional solution from 1974 could satisfy all the claims of the Socialist Republic of Serbia, but also respect the specifics and special interests of the autonomous provinces. Although the conflict was (temporarily) pacified in this way, the issue remained unresolved. For most of its existence in the SFRY, Serbia was loyal and generally subordinate to the federal government. This changed after the death of Josip Broz Tito in 1980, when Albanian, as well as Serbian nationalism in Kosovo arose. In 1981, major protests erupted in Kosovo demanding the status of republic. The League of Communists was split on how to respond. At the same time, an economic crisis in Yugoslavia started. The leaders of the country were unable to carry out any reforms due to the political instability. President of League of Communists of Serbia Slobodan Milošević visited Kosovo in April 1987 and promised rapid action in order to protect peace and the Serbs of Kosovo. Ethnic tensions in Kosovo heated up when a Kosovo Albanian soldier opened fire on his fellow soldiers in Paraćin, in an event known as the Paraćin massacre. Then President of Serbia Ivan Stambolić wanted to make compromise, rather than fast solution. He found himself in a clash with Milošević. This conflict culminated with 8th Session and replacement of Stambolić with Petar Gračanin as President of Serbia.
