According to the legend, the ancestors of today's inhabitants of villages, who settled at the time of the Great Serb Migrations under Arsenije III Čarnojević, were called Bobe.

From 27 December 1920 (when they arrived in Vukovar) soldiers and families of the White Russian émigrés who were followers of Pyotr Wrangel settled in Bobota, Pačetin, Bršadin, Trpinja and Vera.

During that time, the non-Serb population was subjected to unlawful arrests, imprisonment, physical, mental and sexual abuse and killings by the members of local Serb paramilitary formations.

However, the Croatian soldiers of the Croatian National Guard (ZNG) and civilian volunteers, led by Major general Blago Zadro, offered strong resistance, during which they destroyed about 30 JNA tanks and armored vehicles which gave road the nickname "tank graveyard".
