The Nile begins to rise in June, when the snow melts on the Abyssinian mountains. High-water mark, some thirty feet above the ordinary level, is reached in September. The inhabitants then make haste to cut the confining dikes and to spread the fertilizing water over their fields. Egypt takes on the appearance of a turbid lake, dotted here and there with island villages and crossed in every direction by highways elevated above the flood. Late in October the river begins to subside and by December has returned to its normal level. As the water recedes, it deposits that dressing of fertile vegetable mold which makes the soil of Egypt perhaps the richest in the world. [8] EGYPT AN EARLY CENTER OF CIVILIZATION It was by no accident that Egypt, like Babylonia, became one of the first homes of civilized men. Here, as there, every condition made it easy for people to live and thrive. Food was cheap, for it was easily produced. The peasant needed only to spread his seed broadcast over the muddy fields to be sure of an abundant return. The warm, dry climate enabled him to get along with little shelter and clothing. Hence the inhabitants of this favored region rapidly increased in number and gathered in populous towns and cities. At a time when most of their neighbors were still in the darkness of the prehistoric age, the Egyptians had entered the light of history. 9. THE BABYLONIANS AND THE EGYPTIANS INHABITANTS OF BABYLONIA The earliest inhabitants of Babylonia of whom we know anything were a people called Sumerians. They entered the Babylonian plain through the passes of the eastern mountains, three or four thousand years before the Christian era. Here they formed a number of independent states, each with its capital city, its patron god, and its king. After them came Semitic tribes from the deserts of northern Arabia. The Semites mingled with the Sumerians and adopted Sumerian civilization. HAMMURABI, KING OF BABYLONIA, ABOUT 2000 B.C. Of all the early Babylonian kings the most famous was Hammurabi. Some inscriptions still remain to tell how he freed his country from foreign invaders and made his native Babylon the capital of the entire land. This city became henceforth the real center of the Euphrates valley, to which, indeed, it gave its name. Hammurabi was also an able statesman, who sought to develop the territories his sword had won. He dug great canals to distribute the waters of the Euphrates and built huge granaries to store the wheat against a time of famine. In Babylon he raised splendid temples and palaces. For all his kingdom he published a code of laws, the oldest in the world. [9] Thus Hammurabi, by making Babylonia so strong and flourishing, was able to extend her influence in every direction. Her only important rival was Egypt.
