What happened in this minute

Mehmed II's final assault began before dawn. The walls that had held for a thousand years were breached near the Kerkoporta, and Constantine XI died fighting somewhere in the collapse.

The city became Istanbul and the Ottoman capital. Greek scholars carrying manuscripts west contributed to the Renaissance, and the closure of overland trade routes pushed European states toward Atlantic exploration.

The pre-dawn timestamp reflects contemporary accounts of when the final assault began; the exact minute is unrecorded.
