Arab conquest of Egypt
Forces of the Rashidun Caliphate led by Amr ibn al-As conquered Byzantine Egypt between 639 and 642 AD. The conquest ended the Roman period in Egypt, which had begun in 30 BC and lasted for approximately seven centuries, and more broadly concluded the Greco-Roman period of Egyptian history, which had endured for nearly a millennium. Prior to the conquest, Byzantine rule in Egypt had undergone significant political and military disruption.
