Ahmose's son succeeded him, but aside from putting down an uprising of the troublesome Ethiopians, little of importance attached to his administration. It was left for Ahmose's grandson, Thutmose[3] I., to give Egypt the position she was to occupy among the nations for many years. Thutmose I. was instinctively a soldier. Coming to the throne when a mere boy, the Ethiopians made war directly, thinking they could easily overcome so inexperienced a king. Thutmose at once gave indication of his capacity by marching immediately into their territory and defeating them with tremendous slaughter. To prevent further annoyance from these people the king divided their country into districts and over each he placed an Egyptian official. Thus the land of Kush became an Egyptian province. Having now a well organized army, Thutmose pressed into Asia--for the experience of Ahmose had shown that rich plunder there awaited the victor. Some tribes yielded voluntarily to Egypt; others were forced to yield. Although the king penetrated some distance east of the Euphrates, these districts were not permanently won for Egypt. On the contrary, we shall find that subsequent pharaohs did over and over again what this king attempted, and for this reason: each time a nation was conquered, Thutmose withdrew his soldiers from it, imposing tribute and asking hostages. So long as the tribute was forthcoming, the tribe was left undisturbed. This gave wide opportunity for the conquered peoples to unite among themselves and make attempts to shake off control whenever a new ruler succeeded to the throne of Egypt. This proved eventually a most extravagant policy for Thutmose to have followed. Henceforth Egypt had to take her place as a military power, and with her every new aspiring nation had to reckon. When we recall the peaceful Egyptians of early times, secluded in their quiet valley, disliking foreigners and having as little intercourse with them as possible, we realize what a change had been wrought in them by their contact with the Hyksos during the years of their oppression.
