Ramesses II (also known as the Great) became Pharaoh of Ancient Egypt on May 31st in 1279 BC.
Regarded as the most powerful, revered, and greatest pharaoh of the Egyptian Empire, it is believed Ramesses acceded to the throne as the third pharaoh of the Nineteenth Dynasty of Egypt when he was 25.
The oldest known recorded peace treaty in history dates from around 1258 BC (during Ramesses II's rule), between the Egyptian and Hittite empires. A replica of the tablet is on display at the United Nations.
Ramesses II also significantly strengthened the military, and enabled monuments and structures to be erected all over Egypt during a time of great prosperity.
