Tribes in the military service of the Makhzen in precolonial Morocco.
The most important of the Guish tribes were the Sherarda, Sheraga, and Udayay. Guish tribes were distinguished from the Naiba tribes, which were occasionally recruited to serve the Makhzen militarily. They lived on a plot of land offered by the sultan and did not pay taxes. Most of the administrators of the Makhzen were recruited from the Guish tribes.
