The Kushites' powerful rule over Egypt came to an end in 671 B.C., when the Assyrians invaded Egypt. The Assyrians' iron weapons overpowered the bronze weapons used by the Kushites. The Assyrians destroyed the combined Kushite and Egyptian armies. This forced Taharka and the Kushite army to retreat to Napata.
King Taharka died in Napata, and soon after, the Kushites lost their control of Egypt. However, the Kushites had learned from the Assyrians how to make iron. This skill would help them as they set about building a new kingdom.
What caused the Kushites to lose control of Egypt?
The Temples of Abu Simbel
About 1279 B.C. Pharaoh Ramses II had two temples built at Abu Simbel in Nubia. In 1959 Egypt announced plans to build the Aswan High Dam. The lake formed by the dam would cover much of Lower Nubia. A worldwide effort was made to save the temples. The temples were cut into blocks some weighing as much as 30 tons and moved slightly farther away from the Nile and at a higher elevation.
