Pharaoh Sneferu made significant advancements in pyramid construction during his reign that laid the groundwork for future pyramids. He was known for developing the first true smooth-sided pyramid, known as the Red Pyramid, in Dahshur. To overcome the challenges faced in his earlier constructions, Sneferu introduced a more efficient building method utilizing techniques such as smaller, more stable limestone blocks and careful angular construction. This allowed the smooth sides to be achieved. Sneferu's innovations heavily influenced future pyramid architects, notably evident in the Great Pyramid of Giza, built by his son Khufu.
