This basic form of administration continued throughout the Middle Kingdom, though there is some evidence for a major reform of the central government under Senusret III. Records from his reign indicate that Upper and Lower Egypt were divided into separate waret and governed by separate administrators.[1] Administrative documents and private stele indicate a proliferation of new bureaucratic titles around this time, which have been taken as evidence of a larger central government.[65] Governance of the royal residence was moved into a separate division of government.[24] The military was placed under the control of a chief general.[24] However, it is possible that these titles and positions were much older, and simply were not recorded on funerary stele due to religious conventions.[65]
