Who they were
Khufu was the second king of the 4th Dynasty, reigning c. 2589–c. 2566 BC as the son and successor of Sneferu. To the Greeks he was known as Cheops.
What they did
He built the Great Pyramid of Giza. Ironically, his only certain surviving royal statue is a small ivory figurine about 7.5 cm tall, found at Abydos and now in the Egyptian Museum in Cairo.
Legacy
Much later Greek tradition — Herodotus, writing in the 5th century BC — portrayed Khufu as a cruel tyrant who enslaved Egypt to build his pyramid. That is later tradition; the archaeological picture is one of organized, paid labor. His pyramid dominated the skyline of Giza for 4,500 years and made his name one of the most recognizable of ancient Egypt.
