What happened
After a siege of about six weeks, Ottoman forces under Sultan Mehmed II launched a final assault at dawn on 29 May 1453, breaking through Constantinople's ancient land walls with the help of massive cannon. The city, capital of the Byzantine Empire and the last direct institutional link to the Roman world, fell before nightfall, and Mehmed converted the great church of Hagia Sophia into a mosque. In the following months and years, many of Constantinople's Greek scholars fled west to Italy, bringing with them Greek manuscripts of classical texts that had survived in the Byzantine world but were scarce or unknown in the Latin West.
Why it matters
Many modern historians treat the exodus of Greek scholars to Italy after 1453 as a real contributing factor in the transition from the medieval to the Renaissance world, since it gave Italian humanists direct access to Greek philosophy and literature, taught in Florence and Rome by refugee scholars, that Petrarch's generation had only known secondhand or not at all.
How we know
The siege and its date are recorded by multiple eyewitness and near-contemporary chroniclers on both the Ottoman and Byzantine sides; the World History Encyclopedia's account of the siege and Britannica's entry on the fall of Constantinople both describe the assault of 29 May and the subsequent scholarly migration from that record.
