Thebes (ancient Waset) became important in the Middle Kingdom period (2055–1650 BCE). The 11th-dynasty Theban prince Montuhotep II (2055–2004 BCE) reunited Upper and Lower Egypt, made Thebes his capital and increased Karnak’s importance as a cult center to the local god Amun with a temple dedicated to him. The 12th-dynasty pharaohs (1985–1795 BCE) moved their capital back north, but much of their immense wealth from expanded foreign trade and agriculture, and tribute from military expeditions made into Nubia and Asia, went to Thebes, which remained the religious capital. This 200-year period was one of the richest times throughout Egyptian history, which witnessed a great flourishing of architecture and the arts, and major advances in science.
It was the Thebans again, under Ahmose I, who, after the Second Intermediate Period (1650–1550 BCE), drove out the ruling Asiatic Hyksos and unified Egypt. Because of his military victories and as the founder of the 18th dynasty, Ahmose was deified and worshiped at Thebes for hundreds of years. This was the beginning of the glorious New Kingdom (1550–1069 BCE), when Thebes reached its apogee. It was home to tens of thousands of people, who helped construct many of its great monuments.
The greatest contributor of all to Thebes was probably Amenhotep III (1390–1352 BCE). He made substantial additions to the temple complex at Karnak, and built his great palace, Malqata, on the west bank, with a large harbor for religious festivals and the largest memorial temple ever built. Very little of the latter is left beyond the so-called Colossi of Memnon, the largest monolithic statue ever carved. His son Amenhotep IV (1352–1336 BCE), who later renamed himself Akhenaten, moved the capital from Thebes to his new city of Akhetaten (Tell Al Amarna), worshiped one god only (Aten, the solar god), and brought about dramatic changes in art and architecture. After his death, the powerful priesthood was soon reinstated under Akhenaten’s successor, Tutankhamun (1336–1327 BCE), who built very little but became the best-known pharaoh ever when his tomb was discovered full of treasure in 1922. Ramses II (1279–1213 BCE) may have exaggerated his military victories, but he too was a great builder and added the magnificent hypostyle hall to Karnak, other halls to Luxor Temple, and built the Ramesseum and two magnificent tombs in the Valley of the Kings for himself and his many sons.
The decline of Pharaonic rule was mirrored by Thebes’ gradual slide into insignificance: when the Persians sacked Thebes, it was clear the end was nigh. Mud-brick settlements clung to the once mighty Theban temples, and people hid within the stone walls against marauding desert tribes. Early Christians built churches in the temples, carved crosses on the walls and scratched out reliefs of the pagan gods. The area fell into obscurity in the 7th century CE after the Arab invasion, and the only reminder of its glorious past was the name bestowed on it by its Arab rulers: Al Uqsur (The Fortifications), giving modern Luxor its name. By the time European travelers arrived here in the 18th century, Luxor was little more than a large Upper Egyptian village, known more for its 12th-century saint, Abu Al Haggag, buried above the mound of Luxor Temple, than for its half-buried ruins.
The growth of Egyptomania changed that. Napoleon arrived in 1798 wanting to revive Egypt’s greatness and, with the publication of the Description de l’Egypte, did manage to reawaken interest in Egypt. European exhibitions of mummies, jewelry and other spectacular funerary artifacts from Theban tombs (often found by plundering adventurers rather than inquiring scholars) made Luxor an increasingly popular destination for travelers. By 1869, when Thomas Cook brought his first group of tourists to Egypt, Luxor was one of the highlights. Mass tourism had arrived and Luxor regained its place on the world map.
The 1960s saw the start of modern mass tourism on the Nile with Luxor as its epicenter, and more hotels and sights than anywhere else in southern Egypt. The town has since grown into a city of several hundred thousand people, almost all of them dependent on tourism. In the past couple of decades, there have been booms and crashes, the latest crash brought on by the riots that ended the presidencies of Hosni Mubarak and Mohammed Morsi. Tourist numbers have been down since then, and people in Luxor and elsewhere in the south have suffered.
