Merenre Nemtyemsaf II was briefly Pharaoh of Egypt, likely succeeding his long-lived father Pepi II Neferkare. The Turin King List says that Merenre reigned for only a year, after succeeding his father Pepi II. His name is also mentioned on a stela that was discovered near the site of the pyramid of Neith, perhaps his mother.[3] His nomen was formerly read as Antyemsaf, a reading now known to be incorrect.[citation needed]

It was long thought that he was succeeded by Nitocris, who was thought to be his sister/wife. It is now generally recognized that the name "Nitocris" was conflated with that of a male pharaoh named Neitiqerty Siptah instead.[4]

According to Herodotus (Histories ii), he was murdered in a plot and later revenged by his sister Nitocris. -------------------- http://en.wikipedia.org/wiki/Merenre_Nemtyemsaf_II
