Three main regions and three main kinds of wandering and imperfectly settled people there were in those remote days of the first civilizations in Sumeria and early Egypt. Away in the forests of Europe were the blonde Nordic peoples, hunters and herdsmen, a lowly race. The primitive civilizations saw very little of this race before 1500 B.C. Away on the steppes of eastern Asia various Mongolian tribes, the Hunnish peoples, were domesticating the horse and developing a very wide sweeping habit of seasonal movement between their summer and winter camping places. Possibly the Nordic and Hunnish peoples were still separated from one another by the swamps of Russia and the greater Caspian Sea of that time. For very much of Russia there was swamp and lake. In the deserts, which were growing more arid now, of Syria and Arabia, tribes of a dark white or brownish people, the Semitic tribes, were driving flocks of sheep and goats and asses from pasture to pasture. It was these Semitic shepherds and certain more negroid people from southern Persia, the Elamites, who were the first nomads to come into close contact with the early civilizations. They came as traders and as raiders. Finally there arose leaders among them with bolder imaginations, and they became conquerors. STELE GLORIFYING KING NARAM SIN, OF AKKAD STELE GLORIFYING KING NARAM SIN, OF AKKAD This monarch, son of Sargon I, was a great architecht as well as a famous conqueror. Discovered in 1898 among the ruins of Susa, Persia About 2750 B.C. a great Semitic leader, Sargon, had conquered the whole Sumerian land and was master of all the world from the Persian Gulf to the Mediterranean Sea. He was an illiterate barbarian and his people, the Akkadians, learnt the Sumerian writing and adopted the Sumerian language as the speech of the officials and the learned. The empire he founded decayed after two centuries, and after one inundation of Elamites a fresh Semitic people, the Amorites, by degrees established their rule over Sumeria. They made their capital in what had hitherto been a small up-river town, Babylon, and their empire is called the first Babylonian Empire. It was consolidated by a great king called Hammurabi (circa 2100 B.C.) who made the earliest code of laws yet known to history. The narrow valley of the Nile lies less open to nomadic invasion than Mesopotamia, but about the time of Hammurabi occurred a successful Semitic invasion of Egypt and a line of Pharaohs was set up, the Hyksos or “shepherd kings,” which lasted for several centuries. These Semitic conquerors never assimilated themselves with the Egyptians; they were always regarded with hostility as foreigners and barbarians; and they were at last expelled by a popular uprising about 1600 B.C. But the Semites had come into Sumeria for good and all, the two races assimilated and the Babylonian Empire became Semitic in its language and character. XVII THE FIRST SEAGOING PEOPLES
