Final answer:
King Menes, often identified with Narmer, is recognized for unifying Upper and Lower Egypt, symbolized by his wearing of the combined Double Crown.
Step-by-step explanation:
King Menes became the first pharaoh of Egypt by uniting Upper and Lower Egypt. Around 3150 BCE, the regions of Upper Egypt and Lower Egypt, which had previously been politically distinct, were combined into a powerful kingdom. This significant event in history is attributed to a ruler known as Narmer, who is often believed to be the same as Menes. The Narmer Palette depicts this king wearing both the White Crown and the Red Crown, representing his rule over Upper and Lower Egypt, respectively. These crowns, known as the Double Crown when combined, symbolize the unification of Egypt and the pharaoh's divine right to rule the entire land.
