<human>:  What is the history of Ancient Egypt?
<bot>: The history of Ancient Egypt dates back about 5,000 years ago and spans a period of over1,500 years. Ancient Egypt was one of the earliest and longest lasting civilizations in the world. The civilization is split into three different eras: the Old Kingdom, the Middle Kingdom, and the New Kingdom. The Old Kingdom (2700-2200 BC) was a period of great prosperity, when the Egyptians created the pyramids and developed an organized society as well as an organized government. The Middle Kingdom (2134-1690 BC) saw a decline in power and the reunification of Egypt under one ruler, the pharaoh. The New Kingdom (1550-1070 BC) was a period of expansion and great power, when Egypt became the most powerful nation in the Near East. It was during this era when the Egyptian religion, art, and culture flourished.
