The Croatia War of Independence was a defensive war for the indipendence and the integrity of the Croatian state against the Serbian aggression. On the basis of a referendum held on 25th June 1991, the Croatia Parlament adopted the Declaration on the establishment of the sovereign and independent Republic of Croatia. This event in Croatia is commemorated as the Statehood Day. The public lists several different war start dates. Therefore, the historian Ante Nazor explains that, under the international law, the War as a conflict between the two countries began on the same day when the Croatia Parliament proclaimed the independence of the Republic. It lasted from 1991 to 1995. The Republic of Croatia was formed during the War, as an independent and sovereign state, but with numerous human casualties and material losses. The first victims of the war in Croatia were the Croats, the members of the Croatia Police in Plitvice and in Borovo Selo. After that, the killing of the Croatian civilians and the members of the Croatian minorities, the non-Serb population, began, followed by the massacres in Croatian towns and villages.The crimes against the civilian population culminated in the air attacks and the artillery attacks on the hospitals, churches, houses and other civilian targets.
