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.
United States Constitution
The Articles of Confederation and Perpetual Union was the first constitution of the United States. It was drafted by the Second Continental Congress from mid-1776 through late 1777, and ratification by all 13 states was completed by early 1781. The Articles of Confederation gave little power to the central government. The Confederation Congress could make decisions, but lacked enforcement powers. Implementation of most decisions, including modifications to the Articles, required unanimous approval of all thirteen state legislatures.
