The Vukovar massacre, also known as the Vukovar hospital massacre or the Ovčara massacre, was the killing of Croatian prisoners of war and civilians by Serb paramilitaries and the Yugoslav People's Army (JNA) at the Ovčara farm southeast of Vukovar on 20 November 1991, during the Croatian War of Independence. The massacre occurred shortly after Vukovar's capture by the JNA, Croatian Serb Territorial Defence (TO), and paramilitaries from neighbouring Serbia. It was the largest massacre of the war, and the worst war crime in Europe since World War II up until that time.
In the final days of the battle, the evacuation of the Vukovar hospital was negotiated between Croatian authorities, the JNA and the European Community Monitor Mission in cooperation with the International Committee of the Red Cross (ICRC). The JNA subsequently refused the ICRC access to the hospital despite the agreement and removed approximately 300 people from its premises. The group, largely consisting of Croats but also including Serbs, Hungarians, Muslims and two foreign nationals who fought on the side of the Croatian National Guard, was initially transported to the JNA barracks in Vukovar. Several prisoners were identified as hospital staff and removed from the group to be returned to the hospital while the rest of them were transported to the Ovčara farm south of Vukovar. Once at the farm, the prisoners were beaten for several hours before the JNA pulled its troops from the site, leaving the prisoners in the custody of the Croatian Serb TO and Serbian paramilitaries. The prisoners were then taken to a prepared site, shot in groups of ten to twenty and buried in a mass grave.
Vukovar (Croatian pronunciation: [v̞ûkɔv̞aːr]; Serbian Cyrillic: Вуковар) ) is a city in eastern Croatia. It has Croatia's biggest river port, located at the confluence of the Vuka River and the Danube. Vukovar is the seat of the Vukovar-Syrmia County. The city's registered population was 26,468 in the 2011 census, with a total of 27,683 in the municipality.
The name Vukovar means 'town on the Vuka River' (Vuko from the Vuka River, and vár from the Hungarian word for 'fortress'). The name of the Vuka River itself originates from the Slavic word 'vuk', meaning 'wolf'. In other languages, the city in German is known as Wukowar, in Hungarian as Vukovár or Valkóvár, and in Serbian as Вуковар. In the late 17th century, the medieval Croatian name Vukovo was supplanted by the Hungarian Vukovár.
Vukovar is located in the Eastern part of the Republic of Croatia and is the centre of the Vukovar-Syrmia County. Its location places it at the border of historical provinces Eastern Slavonia and Western Syrmia.
