The Battle of Bileća was fought in August 1388 between the forces of the Kingdom of Bosnia led by Grand Duke Vlatko Vuković, and the Ottoman Empire under the leadership of Lala Şahin Pasha. The Ottoman army broke into Hum, the kingdom's southern region. After days of looting, the invaders clashed with the defending force near the town of Bileća, north-east of Dubrovnik. The battle ended with an Ottoman defeat.
