Roman Egypt
Egypt was established as a Roman province in 30 BC after Octavian defeated his rival Mark Antony, deposed Pharaoh Cleopatra, and annexed the Ptolemaic Kingdom to the Roman Empire. The province encompassed most of modern-day Egypt except for the Sinai Peninsula, which would later be conquered by Trajan. Aegyptus was bordered by the provinces of Crete and Cyrenaica to the west and Judea to the East. The province came to serve as a major producer of grain for the empire and had a highly developed urban economy. Aegyptus was by far the wealthiest Eastern Roman province, and by far the wealthiest Roman province outside of Italia. The population of Roman Egypt is unknown; although estimates vary from 4 to 8 million. In Alexandria, its capital, it possessed the largest port, and the second largest city of the Roman Empire.
