Succession to the French throne
In 1791 the French National Assembly drew up a new, written Constitution to which the King gave his assent, and which governed France for the last year of the 18th century monarchy. For the first time it was necessary to define formally, as a matter of statutory constitutional law, the system of succession, and the titles, privileges and prerogatives of the Crown. In debating the succession to the Crown the contemporary understanding of the law of succession was publicly clarified. It rebutted the assertion by some that the claim by the Spanish line is a late construct, made to satisfy the ambitions of princes deprived of other claims. Indeed, it is evident that the issue of the rights of the Spanish line to the French crown remained an important constitutional issue.
French Fourth Republic
A new draft of the Constitution was written, which this time proposed the establishment of a bicameral form of government. Leon Blum of the () headed the from 1946 to 1947. After a new legislative election in June 1946, the Christian democrat Georges Bidault assumed leadership of the Cabinet. Despite de Gaulle's so-called discourse of Bayeux of 16 June 1946 in which he denounced the new institutions, the new draft was approved by 53% of voters voting in favor (with an abstention rate of 31%) in the referendum held on 13 October 1946. This culminated in the establishment in the following year of the Fourth Republic, an arrangement in which executive power essentially resided in the hands of the President of the Council (the prime minister). The President of the Republic was given a largely symbolic role, although he remained chief of the French Army and as a last resort could be called upon to resolve conflicts.
