Fez or Fes (Arabic: فاس [faːs], Berber: ⴼⴰⵙ [faːs], French: Fès) is a city in northern inland Morocco and the capital of the Fas-Meknas administrative region. It is the second largest city in Morocco after Casablanca, with a population of 1. 4 million (2014).
Located to the northeast of Atlas Mountains, Fez is situated at the crossroad of the important cities of all regions; 206 km (128 mi) from Tangier to the northwest,246 km (153 mi) from Casablanca, 169 km (105 mi) from Rabat to the west, and 387 km (240 mi) from Marrakesh to the southwest which leads to the Trans-Saharan trade route. It is surrounded by the high grounds, and the old city is penetrated by the River of Fez flowing from the west to east. Fez was founded under the Idrisid rule during the 8th-9th century. It consisted of two autonomous and competing settlements. The migration of 2000 Arab families in the early 9th century gave the nascent city its Arabic character. After the downfall of the Idrisid dynasty, several empires came and went until the 11th century when the Almoravid Sultan Yusuf ibn Tashfin united the two settlements and rebuilt the city, which became today's Fes el Bali quarter.
