Siege of Belgrade (1456)
Hungarian victory halted Ottoman advance into Europe for 70 years.
The siege of Belgrade (Hungarian: Nándorfehérvár ostroma; Serbian Cyrillic: Опсада Београда) was a military blockade of Belgrade that occurred 4–22 July 1456, in the aftermath of the fall of Constantinople in 1453. Led by Sultan Mehmed II, the Ottoman forces sought to capture the strategic city, then under Hungarian control, which was crucial for maintaining control over the Danube River and the Balkans. The Hungarian defenders, led by Michael Szilágyi and later reinforced by John Hunyadi, successfully repelled the larger Ottoman army, marking a turning point in European efforts to halt Ottoman expansion.

Lore & Background
The siege began on 4 July 1456, when Sultan Mehmed II's army, estimated at 60,000–70,000 men by newer research, surrounded Belgrade. The fortress, considered one of the strongest in Europe, was defended by 5,000–7,000 men under Michael Szilágyi. The Ottomans bombarded the walls with 300 cannons and deployed a fleet of 200 river vessels. On 14 July, John Hunyadi's relief force destroyed a Turkish flotilla on the Danube, allowing him to enter the fortress with fresh troops. A major Ottoman assault on 21 July was repulsed, and the wounded Mehmed II lifted the siege on 22 July.
Reader's Guide
The victory at Belgrade boosted the morale of European Christian forces and was seen as a turning point in their efforts, providing a crucial buffer that temporarily halted Ottoman expansion towards Europe beyond the Balkans for 70 years. John Hunyadi's successful defence earned him widespread acclaim, though he died of the plague a few weeks later. The battle also demonstrated the importance of firearms and artillery in warfare, heralding a new era in military technology and tactics. The struggle between the Ottoman Empire and European powers persisted for centuries.
