The Blue Crown, also known as the Khepresh, is seen from the 18th Dynasty onwards due to Ramses II wearing it into battle. Pharaohs were often shown depicted the Blue Crown as it became known as the War Crown. The Blue Crown was a tall flanged helmet that was adorned with golden discs and had with the Wadjet and Nekhbet on the brow. Below is a relief of Ramses II in his temple at Abydos.
The Nemes Crown was more of a headdress than a crown. Known infamously due to its depiction on the gold mask of Tutankhamen it is the most familiar crown to readers. The Nemes Crown was a piece of striped cloth that was pulled tight across the forehead and tied into a tail at the back while two strands hung down each side of the face. The brow was decorated using the Wadjet and the Nekhbet. A plainer version of the Nemes Crown is known as a khat. Below is a picture of the Great Sphinx at Giza wearing the Nemes Crown.
The Double Crown, also known as the pschent or Two Mighty Ones, symbolized the pharaoh's supremacy of Upper and Lower Egypt. He, the pharaoh, ruled the Two Lands as one, united. With Upper and Lower Egypt unified the red crown and the white crown were often combined to show this event. An early example is a relief of King Sneferu in the 4th Dynasty wearing the pschent. However, just because Egypt was united did not mean that the pharaoh always wore the Double Crown. He still separately wore the crowns of Upper and Lower Egypt depending on the occasion. Below is a relief of a pharaoh being symbolically crowned with the crowns of Upper and Lower Egypt.
