No, Ramesses II did not build the pyramids. The pyramids were constructed long before his time. Ramesses II, also known as Ramesses the Great, was one of ancient Egypt’s most powerful pharaohs, reigning from 1279 to 1213 BCE. The most famous pyramids, such as the Great Pyramid of Giza, were built during the Old Kingdom period, around 2580–2560 BCE, under the reign of Pharaoh Khufu.
Ramesses II is more renowned for his military campaigns, monumental building projects like the temples at Abu Simbel, and his long reign. While he did not build pyramids, his legacy includes numerous statues, temples, and other structures that have left a lasting impact on Egyptian history.
