The history of the city of Beni Mellal is deeply rooted in the past of the Tadla region. Although Berber tribes have inhabited these fertile lands since ancient times, the key moment in the chronicles is considered to be the end of the 17th century. In 1688, Sultan Moulay Ismail ordered the construction of a powerful fortress here, known as Kasbah Bel-Kush, or Kasbah Ras el Ain. This fortification became the core of the future city, designed to ensure security and control over a strategically important territory in the centre of Morocco.
The development of the settlement from a military fortress into an important urban centre was driven by a unique combination of natural and geopolitical conditions:
- Water resources: The main source of life became the famous Ain Asserdoun spring. Its waters turned arid lands into a blooming oasis, which was critical for survival and population growth.
- Geography: Its location at the foot of the Middle Atlas, on the border with a vast plain, made the city a natural point of exchange for goods between highlanders and valley dwellers.
- Strategic position: The city was situated on an important route connecting two imperial centres — Fes and Marrakesh, ensuring a constant flow of merchants and travellers.
The economy of the early period was built primarily on agriculture. Thanks to irrigation systems fed by mountain springs, the region was famous for its olive groves, orchards, and grain crops. The city served not only as the administrative centre of the province but also as the main market for surrounding tribes. Culturally, it represented a fusion of indigenous Berber traditions and Arab influence arriving with trade caravans.
