In August 1990 an insurrection known as Log Revolution started in Serb populated areas of Croatia. Due to recent civil unrest and with Croatia declaring independence from Yugoslavia in June 1991, the Serb majority settlements of eastern Lika joined with fellow Serbian populace in Croatia in the creation and declaration of independence of the Republic of Serbian Krajina (RSK). Subsequently, the Serbian paramilitary units were created with the backing of the Yugoslav National Army and Serbian paramilitary forces.
