During the era of the Roman Empire, most of modern-day Egypt, except for the Sinai, was ruled as the imperial province of Aegyptus, from the time it was conquered by Roman forces in 30 BC, to AD 642. The last few centuries of this period has been called late antique Egypt. The province was bordered by Crete and Cyrenaica to the west and Judaea, later Arabia Petraea, to the East.
