Djoser was an ancient Egyptian pharaoh of the 3rd Dynasty during the Old Kingdom, and was the founder of that epoch. He is also known by his Hellenized names Tosorthros and Sesorthos. He was the son of King Khasekhemwy and Queen Nimaathap, but whether he was also the direct successor to their throne is unclear. Most Ramesside king lists identify a king named Nebka as preceding him, but there are difficulties in connecting that name with contemporary Horus names, so some Egyptologists question the received throne sequence. Djoser is known for his step pyramid, which is the earliest colossal stone building in ancient Egypt. c. 2800 BC – c. 2700 BC; died at about 100. Alive at the same time as Imhotep and Khasekhemwy.
