Some sources ascribe a co-regency period to Senusret II's rule, with his father Amenemhat II as his co-regent. The British Egyptologist Peter Clayton ascribes at least three years of co-regency to Senusret II's reign. The French Egyptologist Nicolas Grimal assigns nearly five years of co-regency prior to sole accession to the throne.
