The fifth king of the 2nd Dynasty was probably
responsible for the unification of Upper and Lower Egypt.
Not much is known about him, save the fact that he
undertook massive military campaigns. A statue of him
which resides in the Cairo Museum, demonstrates the first
use of hard stone work during this period. He is
responsible for the construction of a large granite door
jamb within the temple of Hierakonpolis, and for the
building of many of the mortuary complexes at both
Saqqara and Abydos.
