Besides Filip Višnjić, he is one of the most important Serbian historical figures born in Semberija and as such his likeness appears on the coat of arms of the municipality of Bijeljina.

[1] Knez Ivo, a voivode over all 12 villages of the Bijeljina nahia, in 1806, during the First Serbian Uprising helped in freeing Serbs from the Ottoman rule.

In 1809, he led the insurgents in Semberija in the "offensive plan" in which Karađorđe attempted to liberate the whole of Bosnia and Herzegovina and all Serbian lands in the Balkans.

The new master of Serbia, Prince Miloš Obrenović, allowed Knyaz Ivo to settle again in Šabac in 1820, where he appointed him a member of the Municipal Court.

[1] Knyaz Ivo of Semberija was sung of in Filip Višnjić's song "Knez Ivan Knežević", which also received a historical introduction written by Vuk Karadžić.
