Fall Of Constantinople 1453 - Ottoman Wars

The Eastern Roman Empire was under constant Ottoman pressure ever since the new conquerors appeared in the Anatolia. Although the Ottomans tried to take Constantinople on a number of occasions, they had to lift the siege of the city due to the Crusades of Varna and Nicopolis, the Timurid Invasion and the battle of Ankara, and the Interregnum period that happened after their Sultan Bayezid was taken hostage by Timur. However, after the victories at the battles of Varna (1444) and 2nd Kosovo (1448) against the crusaders of Wladyslaw III and John Hunyadi, the road to Constantinople was open and the new sultan Mehmed II set his sight on the city of the Roman emperors.
