Amenemhat II
Amenemhat II was once believed to have shared a period of coregency with his predecessor Senusret I, an hypothesis based on the double-dated stela of an official named Wepwawetō (Leiden, V4) that bears the regnal year 44 of Senusret I and the regnal year 2 of Amenemhat II. The existence of such coregency is now considered unlikely and the meaning of the double-date on the stela is interpreted as a time range when Wepwawetō was in charge, from Senusret I's year 44 to Amenemhat II's year 2.
