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.
1945 French constitutional referendum
A constitutional referendum was held in France on 21 October 1945. Voters were asked whether they approved of the Assembly elected on the same day serving as a Constituent Assembly, and whether until a new constitution was approved, the country would be governed according to a proposed set of laws that appeared on the ballot paper. If the first proposal had not been approved, the Third Republic would have been restored, but its approval led to the creation of the Fourth Republic. Both were approved by wide margins with a turnout of 79.8%.
