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.
History of France
In July 1790, the Assembly adopted the Civil Constitution of the Clergy. This law reorganized the French Catholic Church, arranged that henceforth the salaries of the priests would be paid by the state, abolished the Church's authority to levy a tax on crops and again cancelled some privileges for the clergy. In October a group of 30 bishops wrote a declaration saying they could not accept the law, and this fueled civilian opposition against it. The Assembly then in late November 1790 decreed that all clergy should take an oath of loyalty to the Civil Constitution of the Clergy. This stiffened the resistance, especially in the west of France including Normandy, Brittany and the Vendée, where few priests took the oath and the civilian population turned against the revolution. Priests swearing the oath were designated 'constitutional', and those not taking the oath as 'non-juring' or 'refractory' clergy.
