Answer:
The Old Kingdom of ancient Egypt spanned between 2686 BC and 2181 BC. The period was also known as the "Age of the Pyramids", as it is recognized by the building of the Great Pyramids of Giza, as well as the Great Sphinx of Giza, which is a large sculpture that has the body of a lion and the head of a human, and is believed to represent the Pharaoh Khafre.
The Middle Kingdom of ancient Egypt spanned the Eleventh and Twelfth Dynasties, and included the rule of Pharaoh Mentuhotep II and Pharaoh Amenemhet III. Mentuhotep II aided the reunification of Egypt following its collapse during the First Intermediate Period, and ultimately restoring political order in Egypt. Mentuhotep II also created a large mortuary complex. During this period, the population flourished in terms of art, such as jewelry making, massive construction projects, and trade. Pharaoh Amenemhet III was responsible for two great projects, the giant waterwheels of Faiyum and the Pyramid of Hawara, which was also popularly referred to as the Labyrinth.
The New Kingdom of ancient Egypt spanned from 1570 BC until 1544 BC, and marked a period of great political and economic affluence. Pharaohs seized significant amounts of land and the Egyptian Empire became large. Rulers that distinguished this period included, Amhose I, Tuthmosis I, Hatshepsut, Amenhotep III, Akhenaten, and Rameses II. Tuthmosis I was the first Pharaoh to be buried in the Valley of Kings, which became the burial site for Egyptian Royalty for more than 500 years. Hatshepsut was among the most successful female Pharaohs in Egypt and ruled for 22 years. During the reign of Amenhotep III, Egyptian prosperity, power, and art reached its peak, and included the building of the Temple of Luxor, which still exists. Rameses II ruled for 67 years and is believed to have built many monuments. :)
