In the 1990 parliamentary elections in Croatia, Franjo Tuđman became the first President of Croatia. He promoted nationalist policies and had a primary goal of the establishment of an independent Croatia. The new government proposed constitutional changes, reinstated the traditional Croatian flag and coat of arms, and removed the term "Socialist" from the title of the republic. In an attempt to counter changes made to the constitution, local Serb politicians organized a referendum on "Serb sovereignty and autonomy" in August 1990. Their boycott escalated into an insurrection in areas populated by ethnic Serbs, mostly around Knin, known as the Log Revolution. Local police in Knin sided with the growing Serbian insurgency, while many government employees, mostly police where commanding positions were mainly held by Serbs and Communists, lost their jobs. The new Croatian constitution was ratified in December 1990, and the Serb National Council formed SAO Krajina, a self-proclaimed Serbian autonomous region.
