Fez or Fes is a city in northern inland Morocco and the capital of the Fès-Meknès administrative region. It is the second largest city in Morocco, with a population of 1.11 million, according to the 2014 census.

Fez has been called the "Mecca of the West" and the "Athens of Africa". It is also considered the spiritual and cultural capital of Morocco.

The Idrisid dynasty or Idrisids were an Arab Muslim dynasty from 788 to 974, ruling most of present-day Morocco and parts of present-day western Algeria. Named after the founder, Idris I, the Idrisids were an Alid dynasty descended from Muhammad through his grandson Hasan. The Idrisids are traditionally considered to be the founders of the first Moroccan state, setting the stage for subsequent dynasties and states centered in this region. Their reign played an important role in the early Islamization of Morocco and also presided over an increase in Arab immigration and Arabization in major urban centers.
