Ivan Kosani

Ivan Kosančić was a Serbian knight who died at the Battle of Kosovo in 1389. Born in the upper Toplica region near Kuršumlija, he was a sworn brother to Miloš Obilić and Milan Toplica. Some narratives suggest they might be siblings due to their shared origin from the Toplica region. Their surnames derive from local geographic features—Kosančić from the Kosanica river and Toplica from the region itself.

In epic poetry, particularly Vuk Karadžić's works, Kosančić is portrayed as a spymaster who spies on the Turks and reports to Prince Lazar. He provides detailed information about the Ottoman army, though Miloš Obilić suggests exaggerating their numbers to affect morale. During Prince Lazar's supper, Kosančić is praised as the most handsome man in the army and sits alongside his sworn brothers.

The trio later feigns surrender and attempts to flee, each leaving a distinct mark: Toplica allows one chariot through, Kosančić two, Obilić three. Kosančić dies after Milan Toplica, with Miloš being the last to fall or be captured. The fortification Ivanova kula, on Mount Radan near Devil's Town, is associated with him.
