The Fourth Dynasty of ancient Egypt (notated Dynasty IV or Dynasty 4) is characterized as a "golden age" of the Old Kingdom. Dynasty IV lasted from c. 2613 to 2494 BC. It was a time of peace and prosperity as well as one during which trade with other countries is documented.
Dynasties III, IV, V and VI are often combined under the group title the Old Kingdom, which often is described as the Age of the Pyramids. The capital at that time was Memphis.
The Fourth Dynasty heralded the height of the pyramid-building age. The relative peace of the Third Dynasty allowed the Dynasty IV rulers the leisure to explore more artistic and cultural pursuits. Sneferu’s building experiments led to the evolution from the mastaba styled step pyramids to the smooth sided “true” pyramids, such as those on the Giza plateau. No other period in Egypt’s history equaled Dynasty IV’s architectural accomplishments. Each of the rulers of this dynasty commissioned at least one pyramid to serve as a tomb or cenotaph.
The pharaohs of the Fourth Dynasty ruled for approximately 120 years, from c. 2613 to 2494 BC. The names in the table are taken from Dodson and Hilton.
Sneferu, the first king of Dynasty IV, is given the credit of completing the first true pyramid, known as the Red Pyramid, after he built and abandoned the Bent Pyramid and probably after he finished the Meidum Pyramid. He also constructed a number of smaller step pyramids, making him the most prolific pyramid builder of the era. It is said that Sneferu had more stone and brick moved than any other pharaoh.
Sneferu's chief wife was Hetepheres I, his half-sister and the mother of his son Khufu. His other two wives bore him more children.
