Who was the Egyptian king that summoned his chief adviser to design his tomb around 2600 BC?

The Egyptian king who summoned his chief adviser to design his tomb around 2600 BC is Zoser. Zoser is famous for the Step Pyramid at Saqqara, which is often considered one of the earliest monumental structures in ancient Egypt and represents a significant development in ancient Egyptian architecture. His architect, Imhotep, designed this tomb, marking a transition from traditional flat-roofed tombs to the more complex, multi-tiered step pyramid form. This monumental building not only served as Zoser's burial site but also symbolized his power and the divine status of the pharaoh in ancient Egyptian culture. The tomb's construction was a pivotal moment in the evolution of royal burial practices, laying the groundwork for the iconic pyramids that would follow in later dynasties.
