Djoser was the first or second king of the 3rd Dynasty (–2650 BC) of the Egyptian Old Kingdom (). He is believed to have ruled for 19 years or, if the 19 years were biennial taxation years, 38 years. He reigned long enough to allow the grandiose plan for his pyramid to be realized in his lifetime.Kathryn A.
