sahure pursued userkaf's policy of appointing non-royal people to high offices. this is best exemplified by the office of vizier, which was exclusively held by princes of royal blood with the title of "king's son" since the mid-fourth dynasty and up until the early fifth dynasty. toward the end of this period princes were progressively excluded from the highest office, an evolution undoubtedly correlated with changes in the nature of kingship. this process, possibly initiated by menkaure because of dynastic disputes, seems to have been completed by sahure's time as from then onwards no royal prince was promoted to vizier. those already in post were allowed to keep their status and so in the early part of sahure's reign vizier sekhemkare was a "king's son" while his successor, werbauba, seems to have been non-royal. in response to this change, the state administration began its expansion as it included more and more non royal people.
