Egypt signed history's earliest known peace treaty, with the Hittites of Anatolia
Around 3150 BC a ruler named Menes joined Upper and Lower Egypt into one state. What followed lasted roughly three thousand years, built pyramids and obelisks, invented planked boats and glassware, and ended not with one collapse but with a queue of conquerors stretching from the Hyksos to Rome.
Most Egyptologists think Menes, the unifier credited with founding the kingdom around 3150 BC under the conventional chronology, was the same man as Narmer. From there the story runs in long stable stretches broken by shakier interludes. The steady eras are the Old, Middle and New Kingdoms, roughly matching the Early, Middle and Late Bronze Age, while the unsettled gaps between them go by the name Intermediate Periods.
The engine behind all of it was the river. The Nile flooded on a schedule farmers could plan around, and irrigation of the valley turned that regularity into grain surpluses. Spare food meant more people and spare labour, which the state spent on mining the desert fringes, organising huge building and farming projects, trading abroad and fielding an army that pushed Egyptian power across the Near East. Running the machine was a class of scribes, priests and officials answering to the pharaoh, with an elaborate religion binding the population together. Egypt also developed its own writing system early.
Its power peaked under the New Kingdom, when Egyptian rule reached deep into Nubia and across a large part of the Levant. A slow decline followed, and outsiders took turns in charge: Hyksos, Kushites, Assyrians, Persians, Greeks and finally Romans. Where to draw the finish line is a matter of definition. Some place it in 332 BC, when Alexander the Great's campaigns closed the Late Period; others choose 30 BC, when Rome absorbed the Ptolemaic kingdom. The Arab conquest of AD 642 then ended nearly a thousand years of Greek and Roman influence.
The legacy list is long. Egyptians worked out quarrying, surveying and building methods for monuments, a mathematical system, practical medicine, farming techniques, faience and new literary forms. Travellers and writers were captivated by the ruins for millennia, and from the early modern period onward, European and Egyptian interest in excavation turned that fascination into systematic study.
