Two thousand years of the Middle Nile end in a pharaoh

Priesthoods and ranked societies were forming in the Nilo-Saharan lands around Nabta Playa and in neighbouring parts of Nubia during the fifth millennium BCE. The trend completed itself along the river toward the end of the fourth, when a drier Sahara pushed people onto the floodplain and concentrated them there, most heavily in Upper Egypt. The first large territorial state may have had its centre at Qustul, south of Egypt proper, among Nilo-Saharan speakers whose rulers were already using the regalia that the small emerging states of Upper Egypt used and that Old Kingdom pharaohs would use after them. Qustul's authority extended south into what is now Sudan, as much as two hundred kilometres west of the Nile, and into the country east of it as well. Set the sequence out in order and the question of whether ancient Egypt belongs to African history stops being a question. It was assembled over two thousand years by African communities in constant contact.

Vignier III sits in Haiti and it carries a radiocarbon date around 3630 BCE. That is the earliest firmly dated human habitation we have on the island. I want to sit with the number for a second, because the arithmetic does something to you. From Vignier III to 1804 is about fifty four centuries. From 1804 to today is a little over two. So more than ninety six percent of the human story on this island happened before the country existed, and almost all of that ninety six percent gets compressed into a single sentence about Taínos in most school curricula. That compression is not an accident of space. It is the shape colonial history gives to a place, where the clock only starts when Europeans arrive to look at it. This entry exists to start the clock earlier.

Around the thirty-fourth century BCE the climate of the eastern Sahara turned sharply drier and stayed that way. Steppe and semidesert grassland that had carried herds for millennia became the desert it is now, though patches held on well enough to support marginal livestock raising as late as about 2000 BCE. The pastoralists living out there had to go somewhere. They moved out of the emerging desert and settled among the communities already living along the Nile. That is the event that produced the Egypt of the textbooks, the thin green ribbon dependent on an annual flood. Before it, this was open country with mobile herders and a river running through it. After it, thousands of people and their cattle were compressed onto a floodplain a few kilometres wide. The competition for land and the density of population that followed drove polities to grow and swallow one another until the whole valley was unified around 3100 BCE.

Genetic work on donkeys points to two separate domestications, one among communities in Somaliland and another farther north along the Red Sea Hills. People in both places would have been speaking early languages of the Cushitic branch of Afrasian, and within that branch linguists can follow a word distinguishing the domestic donkey from the wild one back to roughly 5000 BCE. The linguistic date agrees with the genetic date, and both agree with the archaeology, where domestic donkeys show up in Egypt after 4000 BCE. Three independent lines of evidence converging is what makes a case of this depth solid. Two African communities, neighbours in the Horn, took the same animal in hand at about the same time and set off consequences that reached transport, trade, warfare and the organisation of states across the ancient world. The road from Somaliland to Sumer is one of the least told routes in world history.
