Overview
Roman Egypt was an imperial province of the Roman Empire from 30 BC to AD 641. The province encompassed most of modern-day Egypt except for the Sinai. It was bordered by the provinces of Crete and Cyrenaica to the west and Judaea, later Arabia Petraea, to the East.
Egypt was conquered by Roman forces in 30 BC and became a province of the new Roman Empire upon its formation in 27 BC. Egypt came to serve as a major producer of grain for the empire and had a highly developed urban economy. It was by far the wealthiest Roman province outside of Italy. The population of Roman Egypt is unknown, although estimates vary from . Alexandria, its capital, was the largest port and second largest city of the Roman Empire.
Three Roman legions garrisoned Egypt in the early Roman imperial period, with the garrison later reduced to two, alongside formations of the Roman army. The major town of each nome (administrative region) was known as a metropolis and granted additional privileges. The inhabitants of Roman Egypt were divided by social class along ethnic and cultural lines. Most inhabitants were peasant farmers, who lived in rural villages and spoke the Egyptian language. In each metropolis, the citizens spoke Koine Greek and followed a Hellenistic culture. However there was considerable social mobility, increasing urbanization, and both the rural and urban population were involved in trade and had high literacy rates. In AD 212, the Constitutio Antoniniana gave Roman citizenship to all free Egyptians.
The Antonine Plague struck in the late 2nd century, but Roman Egypt recovered by the 3rd century. Having escaped much of the Crisis of the Third Century, Roman Egypt fell under the control of the breakaway Palmyrene Empire after an invasion of Egypt by Zenobia in 269. The emperor Aurelian successfully besieged Alexandria and recovered Egypt. The usurpers Domitius Domitianus and Achilleus took control of the province in opposition to emperor Diocletian, who recovered it in 297–298. Diocletian then introduced administrative and economic reforms. These coincided with the Christianization of the Roman Empire, especially the growth of Christianity in Egypt. After Constantine the Great gained control of Egypt in AD 324, the emperors promoted Christianity. The Coptic language, derived from earlier forms of Egyptian, emerged among the Christians of Roman Egypt.
