The Fifth Dynasty of ancient Egypt (notated Dynasty V) is often combined with Dynasties III, IV and VI under the group title the Old Kingdom. The Fifth Dynasty pharaohs reigned from approximately 2494 to 2345 BC.
Known rulers in the Fifth Dynasty are listed below. The pharaohs of this dynasty ruled for approximately 150 years. The Horus names and most names of the Queens are taken from Dodson and Hilton.
Manetho writes that the Dynasty V kings ruled from Elephantine, but archeologists have found evidence clearly showing that their palaces were still located at Ineb-hedj ("White Walls").
As before, expeditions were sent to Wadi Maghareh and Wadi Kharit in the Sinai to mine for turquoise and copper, and to quarries northwest of Abu Simbel for gneiss. Trade expeditions were sent south to Punt to obtain malachite, myrrh, and electrum, and archeological finds at Byblos attest to diplomatic expeditions sent to that Phoenician city. Finds bearing the names of several Dynasty V kings at the site of Dorak, near the Sea of Marmara, may be evidence of trade but remain a mystery.
How Pharaoh Userkaf founded this dynasty is not known for certain. The Papyrus Westcar, which was written during the Middle Kingdom, tells a story of how king Khufu of Dynasty IV was given a prophecy that triplets born to the wife of the priest of Ra in Sakhbu would overthrow him and his heirs, and how he attempted to put these children - named Userkaf, Sahure, and Neferirkare - to death; however in recent years, scholars have recognized this story to be at best a legend, and admit their ignorance over how the transition from one dynasty to another transpired.
