Hassan II of Morocco Sultan to King in 1957. Hassan was proclaimed Crown Prince on 19 July 1957, and became King on 26 February 1961, after his father's death. Hassan's conservative rule, one characterized by a poor human rights record, strengthened the Alaouite dynasty. In Morocco's first constitution of 1963, Hassan II reaffirmed Morocco's choice of a multi-party political system, the only one in the Maghreb at that time. The constitution gave the King large powers he eventually used to strengthen his rule, which provoked strong political protest from the UNFP and the Istiqlal parties that formed the backbone of the opposition. In 1965,
Mohamed Medbouh was achieved without difficulty. He became governor of Casablanca and then Minister of Posts. King Hassan II succeeded to the throne on 26 February 1961. Medbouh was made the king's chief aide-de-camp. In July 1963 an alleged plot by the leftist National Union of Popular Forces party to kill the king in his bed was foiled. The plotters were said to have obtained detailed plans of the palace from Major Mohamed Medbouh, although Medbouh was not implicated. He was made head of the Royal Military Cabinet in 1967. He often went riding with Hassan II, or played golf with him.
