After the fall of the Ottoman Empire, Tunisia became a French protectorate and the declining malouf was revitalized. Baron Rodolphe d'Erlanger, a French-naturalized Bavarian living near Tunis, commission a collection of ancient works, working with Ali al-Darwish of Aleppo. Al-Darwish and d'Erlanger's pioneering study of Tunisian music was presented at the International Congress of Arabic Music, held in 1932. Baron Rodolphe d'Erlanger died only a few months after the congress, which revolutionized Arab music across the world. In Tunisia, the meeting inspired The Rachidia, which was formed in 1934 to preserve the malouf. The Rachidia undertook some alterations, revising lyrics that were considered profane, and also constructed two performance spaces in the old city of Tunis. The Institute also helped to transition malouf from being performed by folk ensembles with only a few instrument (including 'ud, tar, darbuka, rabab and bendir) to symphonic pieces inspired by Western classical music and Egyptian ensembles.
