Egypt was a dominant power during the time of the New Kingdom because of their rulers and tools. Hatshepsut was able to strengthen the empire by making them more rich through trade (they used the Nile River to reach the Mediterranean to trade with far away peoples). The other pharaohs of the New Kingdom, including Thutmose III, were able to make Egypt powerful by using bronze weapons, two-wheeled chariots, and many different kinds of people in the army (archers, charioteers, and foot soldiers). The lands they controlled gave the Egyptians wealth and new ideas, which allowed the Egyptians to become more powerful so as to be able to take control of other lands. This process repeated until Egypt's decline. The Egyptian empire declined because it was attacked by many invaders, including the "Sea Peoples," who may have included the Philistines, the tribes of Canaan that were ruled by Egyptian overlords, and the Libyans. The Egyptian dynasty never recovered to its previous power after these invasions, and the Libyans took over Egypt.
