Battle of Otlukbeli

August 11, 1473

Mehmed II crushed Uzun Hasan's Aq Qoyunlu army with Ottoman artillery and janissary discipline in eastern Anatolia. The defeat ended Aq Qoyunlu ambitions westward and secured the Ottoman eastern frontier. Uzun Hasan retreated to Tabriz and focused on diplomatic contacts with Venice. Ottoman supremacy in the region was now unchallenged.
