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.
Constitution of the Year III
It remained in effect until the coup of 18 Brumaire (9 November 1799) effectively ended the Revolution and began the ascendancy of Napoleon Bonaparte. It was more conservative than the abortive democratic French Constitution of 1793. The Constitution of the Year III established a liberal republic with a franchise based on the payment of taxes, similar to that of the French Constitution of 1791; a bicameral legislature, (Council of Ancients, and a Council of 500) to slow down the legislative process; and a five-man Directory. The central government retained great power, including emergency powers to curb freedom of the press and freedom of association. The Declaration of Rights and Duties of Mankind at the beginning of the constitution included an explicit ban on slavery. It was succeeded by the Constitution of the Year VIII, which established the Consulate.
