1453

Year 1453 (MCDLIII) was a common year starting on Monday of the Julian calendar, the 1453rd year of the Common Era (CE) and Anno Domini (AD) designations, the 453rd year of the 2nd millennium, the 53rd year of the 15th century, and the 4th year of the 1450s decade. 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 Eastern Roman Empire, due to the Fall of Constantinople.

January–December

 * April – Tarabya and Studius are taken by the Ottoman Empire, in preparation for the assault on Constantinople, as are the Prince Islands, by the Ottoman fleet under Admiral Baltaoglu.
 * April 6–May 29 – Siege and Fall of Constantinople: The Ottoman Sultan Mehmed the Conqueror puts a decisive final end to the Roman Empire, nearly one and a half thousand years after its foundation by Augustus, by capturing the capital, Constantinople. 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, and ends the Middle Ages.
 * May 22 – May 1453 lunar eclipse, a partial eclipse, is visible during the siege of Constantinople.
 * July 17 – Battle of Castillon: In the last pitched battle of the Hundred Years' War, the French under Jean Bureau defeat the English under the Earl of Shrewsbury, who is killed.
 * July 23 – Battle of Gavere in Flanders: Philip the Good, Duke of Burgundy, is victorious over the rebels of Ghent, leading to surrender of their city and the end of the Revolt of Ghent.
 * October 19 – The French recapture Bordeaux, ending the Hundred Years' War and leaving the English retaining only Calais on French soil.
 * October 28 – Ladislaus the Posthumous is crowned King of Bohemia, although George of Poděbrady remains in control of the government.
 * November 10 – Sejo of Joseon kills his enemy General Kim Jong-seo and gains control of the government in Joseon Korea (where this rebellion is called Gyeyujeongnan).
