Final answer:
The pharaoh in question is Ramses II, known for his long reign, military campaigns against the Hittites, and extensive building projects including Abu Simbel.
Step-by-step explanation:
The pharaoh who fought against the Hittites at the Battle of Kadesh, ruled Egypt for 67 years, and built more temples and monuments than any other pharaoh is Ramses II. This pharaoh, also known as Ramses the Great, led numerous military campaigns, including those against the Hittites, and was a prolific builder, leaving behind monuments such as the Great Temple of Abu Simbel and the new capital city of Pi-Ramesse. Ramses II's rule marked the last period of great pharaonic power in the New Kingdom of Egypt.
