Tovarnik (pronounced [tǒvaːrniːk], Serbian Cyrillic: Товарник, Hungarian: Felsőtárnok, German: Sankt Georg, Latin: Ulmo) is a municipality in the Vukovar-Syrmia County in Croatia next to the border with Serbia with the town of Šid and the village of Ilinci on the other side of the border.

Tovarnik is underdeveloped municipality which is statistically classified as the First Category Area of Special State Concern by the Government of Croatia.

[6] During the classical time the settlement called Ulmo existed at the place of modern-day Tovarnik in what was then Roman province Pannonia Secunda.

The historical Serb village of Ivanci, which was located south of Ilača, was completely destroyed on 30 November 1943 while 73 inhabitants were murdered in half an hour by Nazi German forces.

In order to settle the matter, the federal authorities set up a five-member commission presided over by Milovan Đilas in June 1945.

Commission's demarcation was partially changed in several instances including in the case of District of Šid where Tovarnik, Ilača and Šidski Banovci were subsequently transferred to the Socialist Republic of Croatia.

[7] At the time of March 1991 Croatian census out of total 3001 inhabitants of Tovarnik there was 2136 (71,2%) Croats, 670 (22,3%) Serbs, 105 Yugoslavs and 90 members of other groups.

[11] Serb forces had expelled 95% of the 2,500 Croat inhabitants by the end of 1991 and had destroyed 75% of the homes and buildings in the village.

[12] After the signing of the Erdut Agreement in 1995 between the authorities of the Republic of Croatia and the local Serb authorities of the self-proclaimed Eastern Slavonia, Baranja and Western Syrmia the region came under the direct administration of the United Nations Transitional Administration for Eastern Slavonia, Baranja and Western Sirmium which lasted for two years between 1996 and the beginning of 1998.

Parts of the Croatia-Serbia border are known minefields from the Croatian War of Independence period, which represent a considerable threat for unfamiliar individuals.

[14][15] Croatian Prime Minister Zoran Milanović said his country is ready to help refugees coming to Europe, insisting that people fleeing conflict should be given the right to remain in the EU.
