Year 1453 (MCDLIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. It is sometimes cited as the notional end of the Middle Ages by historians who define the medieval period as the time between the Fall of the Western Roman Empire and the fall of the Byzantine (Eastern Roman) Empire.
- April – Tarabya and Studius are taken by the Ottoman Empire in preparation for the assault on Constantinople, as are the Princes' Islands, by the Ottoman fleet under Admiral Baltaoglu.
- April 2–May 29 – Siege and Fall of Constantinople: The Ottoman Sultan Mehmet II the Conqueror ends the Byzantine (or Eastern Roman) Empire after more than a thousand years by capturing the capital, Constantinople (modern-day Istanbul). Mortars are perhaps used in battle for the first time in this action. The consequent closure of the traditional overland route from Western Europe to the Far East and need to identify new maritime routes leads to the Age of Discovery.
