An independence movement lasting many decades eventually prevailed, leading to the end of the French protectorate. In 1954 the Tunisian struggle and consequent civil disturbances resulted in the start of negotiations for autonomy between France and the Neo Destourpolitical party supported by the Tunisian labor unions and by the Arab League. The agreed Convention of April, 1955, stated that France would retain control of the army and foreign affairs while granting autonomy, which was to begin the following year. Bourguiba was released from prison by the French to a tumultuous welcome. This compromise, however, split the Neo Destour; eventually it led to suppression of its left wing, and expulsion of its radical, pan-Arab leader Salah ben Youssef, who later fled to Egypt. This resolution of intra-party strife signalled that Neo Destour would pursue a moderate path. The French then terminated their protectorate over Morocco, in order to concentrate their forces in Algeria. In reaction, and following the strong public opinion voiced by Tunisians, Bourguiba pressed for independence. The French, overcoming the heated objections of the French settlers, eventually acceded and protocols were drafted. On 20 March 1956, Tunisia achieved its full sovereignty. In July Tunisia's application for membership in the United Nations was accepted. The French conceived an independent Tunisia as a constitutional monarchy ruled by the Bey of Tunis, Muhammad VIII al-AminBey. The Bey was an institution that dated back to the early Ottoman era. The prior Bey Muhammad VII al-Munsif had been a popular nationalist, but Amin Bey was both considered by some to be compromised by the French, by others to be a youssefist. Already scheduled elections were held on 25 March 1956; due to secret arrangements negotiated by Bourguiba with the Bey the voters choose only party lists, not candidates. This arrangement made it easier for the Neo Destour party to keep out any youssefist or other dissidents, and to maintain party discipline. The elections were then swept by the Neo Destour party, whose leader Habib Bourguiba became prime minister. On 25 July 1957, the monarchy was abolished, the beylical office terminated, and Tunisia proclaimed a Republic. The assembly then made Bourguiba the first president, of what would be a single-party state.
