Cities Of Pharaohs

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, arts, 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 Great Sphinx and the Pyramids of Giza, built during the Old Kingdom, are modern national icons that are at the heart of Egypt's thriving tourism industry.

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 Hanging Church of Cairo, first built in the third or fourth century AD, is one of the most famous Coptic Churches in Egypt.

The New Kingdom (c.1550−1070 BC) began with the Eighteenth Dynasty, marking the rise of Egypt as an international power that expanded during its greatest extension to an empire as far south as Tombos in Nubia, and included parts of the Levant in the east. This period is noted for some of the most well-known Pharaohs, including Hatshepsut, Thutmose III, Akhenaten and his wife Nefertiti, Tutankhamun and Ramesses II. The first historically attested expression of monotheism came during this period in the form of Atenism. Frequent contacts with other nations brought new ideas to the New Kingdom. The country was later invaded and conquered by Libyans, Nubians and Assyrians, but native Egyptians eventually drove them out and regained control of their country
