 Even after the Treaty of Fes, France waged wars of conquest in Morocco, notably the Zaian War in the Atlas and the Rif War in the north.France recruited infantry from its colony in Morocco to join its "troupes coloniales", as it did in its other colonies in Africa and around the world.Throughout World War I, a total of 37,300-45,000 Moroccans fought for France, forming a "Moroccan Brigade."
