May 1958 crisis

After his time as governor general, Soustelle returned to France to organize support for de Gaulle's return to power, while retaining close ties to the army and the pieds-noirs. By early 1958, he had organized a coup d'état, bringing together dissident army officers and pieds-noirs with sympathetic Gaullists. An army junta under General Massu seized power in Algiers on the night of May 13, thereafter known as the May 1958 crisis.
