The Fall of Constantinople refers to the capture of the Byzantine Empire's capital by the Ottoman Empire on Tuesday, May 29, 1453 (Julian Calendar).

The event marks the end of the political independence of the millennium-old Byzantine Empire, which is by now already fragmented into several Greek monarchies.

Most important, the fall of Constantinople accelerates the scholarly exodus of Byzantine Greeks, which causes the influx of Classical Greek Studies into the European Renaissance.

In addition, it plays a crucial role in Ottoman political stability and its subsequent expansion in the Eastern Mediterranean and the Balkans.

The date of the event is one of the frequently proposed events marking the end of the Middle Ages as a historical period.
