Idvor is situated near the Tamiš river, 35km from Zrenjanin and 43km from Pančevo, in the Banat region of Serbia.

Another wave of Serbs came to the town near the end of the 17th century during the Great Migrations, led by Arsenije III Crnojević.

The Serbs arrived from Patriarchate of Peć region to serve as guardians of the Austrian military frontier against the Ottomans.
