Kurulus Osman Season 3 Episode 4 May 2026

Osman enters the divan (council) with a limp, a ruse to project weakness. Bala Hatun notices the deception in his eyes but says nothing. Geyhati’s emissary, a scarred Mongol named Bayju, sneers as Osman agrees to the tribute. “The Kayı bow to the eternal sky,” Osman says, head lowered.

Across the valley, Nikola watches from the walls of İnegöl. He has learned of the Mongol demand and sees an opportunity. He sends a spy dressed as a dervish to Söğüt, carrying a poisoned letter.
