In 1773, the Sultan Sidi Mohammed ben Abdallah made of Fédala a grains warehouse of Tamasna province and built the Kasbah to protect the shops for traders.

During the precolonial period, competition between the Western powers to ensure the economical exploitation of Africa was behind the merger of Europeans interests in the ports of Morocco.

The Treaty of November 4, 1911 between France and Germany on the partition of Africa forced the Mannesmann family to abandon the lands they held for Georges and Jacques Hersent, two French industrialists, who noticed the existence of a natural bay, valuable for the creation of a large port at low cost.

The rapid growth of the city started around the port, which allowed the development of various industries such as canning fishery products, agro-industry plants, tannery, textile, etc..

[5] The invasion was carried out by the Center Attack Group of the Western Task Force which landed on the Atlantic coast of Morocco.

Fédala was renamed Mohammedia on 25 June 1960 in honor of King Mohammed V, the restorer of Moroccan independence, on the occasion of laying the foundation stone of the Samir oil refinery.

In addition, people call it madinat lwurud wa riyada which means "city of flowers and sports".

[citation needed] Within the past decade, Mohammedia's beaches "Sablet & Mimosa" have drawn many people from Casablanca, and its nearby cities.

Sablet and Mimosa have been under development, building new beach condos, villas, as well as more investments in small businesses which creates more jobs.

The moderating effect of the Atlantic Ocean influences strongly on the city climate and makes its winter soft and warm, and its summer hot and cool.

It represents the historical heart of the city and has marked a transitional compromise between an urbanism of modern buildings and monuments, and the forms of ancient old Medina.

This district is located southern in the city on a gentle hill slope, which gives it the name Al-Alia that means the upper side.

It was built in 1948 as a solution to the shantytowns problem, where rural population were living, attracted by the industrial development of the city and looking for a job.
