Dethronement
T'hami regarded the Sultan's order as a personal insult that must be wiped out at all costs. In addition, the Makhzen was dominated by Fassis (those from the city of Fez), and there was a traditional mutual distrust between the Fassis and those from Marrakech. In T'hami's memory was of the humiliation of himself and his brother Si Madani at the hands of a Fassi-dominated Makhzen during the reigns of Moulay Abdelaziz and Moulay Hafid.
From that moment on he conspired with Abd El Hay Kittani and the French to replace Mohammed V with a new sultan, an elderly member of the royal family named Ben Arafa. On 17 August 1953, Kittani and the Glaoui unilaterally declared Ben Arafa to be the country's imām. On 25 August 1953, the French Resident had the Sultan and his family forcibly seized and deported to exile, and Ben Arafa was proclaimed the new sultan.
