Negoslavci (Serbian Cyrillic: Негославци,[6] Hungarian: Negoszlovce) is a village and a municipality in Vukovar-Syrmia County in eastern Croatia.
Landscape of the Negoslavci Municipality is marked by the Pannonian Basin plains and agricultural fields of maize, wheat, common sunflower and sugar beet.
[8] During the Ottoman era, Negoslavci was designated as "Nigoslavci," and its considerable land holdings extended up to the nearby village of Sotin.
[8] The departure of Roman Catholic ethnic Croats from Negoslavci following the Ottoman retreat from Syrmia remains under unspecified circumstances.
[8] According to local tradition, the settlement's origin traces back to the period of the Great Migrations of the Serbs after the Treaty of Karlowitz, when approximately 15-20 Serbian families seeking refuge from Ottoman territories settled in Negoslavci.
The village endured a protracted period of limited population growth due to challenging living conditions and disease outbreaks.
During the World War II in Yugoslavia and the Genocide of Serbs in the Independent State of Croatia Johann Pfeiffer, a member of the local German community from Vukovar, served as the village's administrator.
[9] Pfeiffer's active involvement in aiding local Serbs to evade Wehrmacht and Ustashe incarcerations resulted in his family being exempt from the subsequent post-World War II expulsion of Germans from Yugoslavia.
[16] Negoslavci is underdeveloped municipality which is statistically classified as the First Category Area of Special State Concern by the Government of Croatia.
There are two ossuaries from the period of World War II with the bones of Yugoslav Partisan fighters from the time of Syrmian Front.
"[22] On the second one with the unknown number of fighters there is Cyrillic inscription "You who have shed your blood, you who have given your young lives, You who have fall for the sake of freedom, We honor you with the greatest glory and thankfulness.
"[22] Negoslavci attracted media attention in Croatia and abroad after its consistent elections patterns, which were different from the predominantly conservative ones in Slavonia.
