Sekhemib-Perenmaat

Sekhemib-Perenma'at (or simply Sekhemib), is the Horus name of an early Egyptian pharaoh who ruled during the 2nd Dynasty. Similar to his predecessor, successor, or co-ruler Seth-Peribsen, Sekhemib is well attested in contemporary, archaeological records, but does not appear in any posthumous documentation. The exact length of his reign is unknown, and his burial site has yet to be identified.
