9 September – On this day
The Battle of Krbava Field was fought between the Ottoman Empire of Bayezid II and an army of the Kingdom of Croatia, at the time in personal union with the Kingdom of Hungary, on this day in 1493, in the Lika region in Croatia.
The Ottoman forces were under the command of Hadım Yakup Pasha, and the Croatian army was led by Emerik Derenčin, Ban of Croatia, who served under King Vladisluas II Jagiello. Earlier in the summer of 1493, the Ottomans undertook a raid through Croatia into Carniola and Styria. Around the same time, clashes had been raging in Croatia between the House of Frankopan and the Croatian ban, but news of the Ottoman incursion forced them to make peace. The Croatian nobles assembled a large army and intercepted the Ottoman forces that were returning to Bosnia. Poor tactics, and the choice of an open battle with the more experienced Ottoman cavalry, resulted in the total defeat of the Croatian army.
There were no immediate territorial gains for the Ottoman Empire, but in the following decades the Ottomans gradually expanded into southern Croatia.
