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 Constitution of 1791
After very long negotiations, the constitution was reluctantly accepted by King Louis XVI in September 1791.
Redefining the organization of the French government, citizenship and the limits to the powers of government, the National Assembly set out to represent the interests of the general will. It abolished many “institutions which were injurious to liberty and equality of rights”. The National Assembly asserted its legal presence in French government by establishing its permanence in the Constitution and forming a system for recurring elections. The Assembly's belief in a sovereign nation and in equal representation can be seen in the constitutional separation of powers. The National Assembly was the legislative body, the king and royal ministers made up the executive branch and the judiciary was independent of the other two branches. On a local level, the previous feudal geographic divisions were formally abolished, and the territory of the French state was divided into several administrative units, Departments ("Départements"), but with the principle of centralism.
