The city is located nearby the Loukous river, making El-Ksar-el-Kebir one of Morocco's richest agricultural regions.

King Abd al-Malik's victory gave Morocco substantial strength and international prestige.

The city experienced substantial growth with the settling of a critical garrison in 1911 as a part of the Spanish protectorate in Morocco.

After Morocco's independence and the Oued el Makhazine reservoir was built by King Hassan II to manage the Loukkos' river regime, the city became an important regional agricultural distribution center.

El-Ksar el-Kebir is reputed for the leading artists, writers, poets and sportsmen on national plane.
