Events in 2590 BC – 2580 BC 1

• 2613 BC – 2589 BC Sneferu -- the experimental pyramid builder Sneferu (c.2613-2589 BC), first pharaoh of the Fourth Dynasty, builds three pyramids -- more than any other pharaoh -- in the process inventing the true pyramid form. His first attempt at Meidum begins as a step pyramid and is converted to a true pyramid but collapses. His Bent Pyramid at Dahshur changes angle halfway up, apparently because the lower slope proved too steep. His Red Pyramid at Dahshur is the world's first successful true pyramid. The accumulated learning from these three experiments -- about angle, foundation, internal structure and construction logistics -- makes Khufu's Great Pyramid possible. Sneferu moves more stone than any other pharaoh in history.
