Before Egypt became part of the Byzantine realm, Christianity had been brought by Saint Mark the Evangelist in the AD first century. Diocletian’s reign marked the transition from the Roman to the Byzantine era in Egypt, when a great number of
Egyptian Christians were persecuted. The New Testament had by then been translated into Egyptian. After the Council of Chalcedon in AD 451, a distinct Egyptian Coptic Church was firmly established.
A unified kingdom was founded circa 3150 BC by King Menes, giving rise to a series of dynasties that ruled Egypt for the next three millennia. Egyptians subsequently referred to their unified country as tawy, meaning “two lands”, and later kemet (Coptic: kīmi), the “black land”, a reference to the fertile black soil deposited by the Nile river. Egyptian culture flourished during this long period and remained distinctively Egyptian in its religion, [[Art of Ancient language and customs. The first two ruling dynasties of a unified Egypt set the stage for the Old Kingdom period, c.2700−2200 BC., famous for its many pyramids, most notably the Third Dynasty pyramid of Djoser and the Fourth Dynasty Giza Pyramids.
The First Intermediate Period ushered in a time of political upheaval for about 150 years. Stronger Nile floods and stabilization of government, however, brought back renewed prosperity for the country in the Middle Kingdom c. 2040 BC, reaching a peak during the reign of Pharaoh Amenemhat III. A second period of disunity heralded the arrival of the first foreign ruling dynasty in Egypt, that of the Semitic Hyksos. The Hyksos invaders took over much of Lower Egypt around 1650 BC and founded a new capital at Avaris. They were driven out by an Upper Egyptian force led by Ahmose I, who founded the Eighteenth Dynasty and relocated the capital from Memphis to Thebes.
The Thirtieth Dynasty was the last native ruling dynasty during the Pharaonic epoch. It fell to the Persians in 343 BC after the last native Pharaoh, King Nectanebo II, was defeated in battle. Later, Egypt fell to the Greco–Macedonians and Romans, beginning over two thousand years of foreign rule. The last ruler from the Ptolemaic line was Cleopatra VII, who committed suicide with her lover Marc Antony, after Caesar Augustus had captured them.
