It is not known how, but Senusret III finally brought an end to the nomarch / nobility - a new administration took full control over the internal government, he divided the country into 3 administrative departments - North, South and Head of the South (Nubia) all of which reported to the Pharaoh's Vizier).
As with most pharoahs, money gained from his Nubian campaigns was re-directed into building works.
This scenario attempts to recreate his reign. Hope you enjoy it.
