It is the period that followed the Archaic Period. The first king of this period was Sanakht, while the most famous king was Djoser, the owner of the step pyramid complex in Saqqara, the first stone building in history. His successors followed in his footsteps and built their tombs in the pyramid shape, which gave the name “Pyramids’ Builders Age” to this period. Most famous are the three pyramids of Giza. The Old Kingdom included four dynasties. During that period the Egyptian civilization progressed rapidly and the central authority became more powerful in addition to the advancements in the army, construction, art and hieroglyphic writing.
