Ramesses II (; , , ; ), commonly known as Ramesses the Great, was an Egyptian pharaoh. He was the third ruler of the Nineteenth Dynasty. Along with Thutmose III of the Eighteenth Dynasty, he is often regarded as the greatest, most celebrated, and most powerful pharaoh of the New Kingdom, which itself was the most powerful period of ancient Egypt. In ancient Greek sources, he is called Ozymandias, derived from the first part of his Egyptian-language regnal name: .
