Khufu was the second Egyptian Pharaoh of the Fourth Dynasty. His full name was Khnum-Khufu, after the God Khnum, one of the earliest-known deities in ancient Egyptian history. Khufu, often described as a cruel leader, succeeded his father Sneferu as King. Unlike his father, he was not seen as a beneficent ruler and he is generally described heartless. His greatest legacy is the Great Pyramid of Giza, one of the seven wonders of the ancient world and the only one to remain largely intact. It remained the tallest structure made by humans for more than 4000 years. The way and means of its construction remains a mystery to this day.
