The three kingdoms were the Old, Middle, and New Kingdoms. The first pharaoh of the Old Kingdom was Djoser, who ruled Egypt from 2630-2611 B.C. He was responsible for the construction of one of the very first pyramids ever built by the ancient Egyptians. His “step” pyramid at Saqqara started the Egyptian tradition of constructing pyramids as burial places for pharaohs. Mentuhotep II is credited with being the founder of the Middle Kingdom. He ruled from Thebes after defeating the 10th dynasty rulers who controlled Lower Egypt, and re-unified the country. The First Pharaoh of the New Kingdom and the 18th dynasty was Ahmose. He reigned from 1550-1525 B.C. He successfully drove the Hyksos from Egypt, and also invaded Palestine and advanced into Nubia. He restored temples that had long been neglected and erected chapels in honor of his family. When he died, a prosperous Egypt was left after his reign. Sorry that this is so long lol
