Pepi II (c. 2284 BCE - c. 2184 BCE) was a ruler of the Sixth Dynasty in Egypt's Old Kingdom. His throne name, Neferkare (Nefer-ka-Re), means "Beautiful is the Ka of Re". He was once thought to be the son of Pepi I and Queen Ankhesenpepy II but it is now believed Pepi II was rather the son of Merenre, who married Ankhesenpepy after Pepi I's death--based on an inscription from a block of white limestone from her mortuary temple, according Audran Labrousse, director of the French Archaeological Mission.[1] Pepi II would, hence, be the grandson of Pepi I instead. He succeeded to the throne at age six, after the premature death of his father, and is generally thought to have ruled for 94 years (c. 2278 BC - c. 2184 BC), the longest reign of any monarch in history, though this has been disputed
