Battle of Kosovo (1448)Kosovo
In 1448, John Hunyadi saw the right moment to lead a campaign against the Ottoman Empire. After the defeat at the Battle of Varna (1444), he raised another army to attack the Ottomans. His strategy was based on an expected revolt of the Balkan people, a surprise attack, and the destruction of the main force of the Ottomans in a single battle. In the three-day battle the Ottoman army under the command of Sultan Murad II defeated the Crusader army of regent John Hunyadi.
