Wasita (title)
Wāsiṭa ("intermediary") was a title given to the senior administrative official in Fatimid Egypt in the late 10th and early 11th centuries. The title signified the role of the chief minister as the "intermediary" between the Fatimid caliphs and the administration and the people, but was junior to the rank of vizier (wazīr), which was more common in the Islamic world.
