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 Islamic Republic of Iran
It is said that the thought of writing constitutional law in Iran has existed since when Ruhollah Khomeini was driven away to Paris before the overthrow of the Pahlavi dynasty in the Iranian Revolution. In other words, the thought of the Iranian constitution had existed in the second half of 1979 and its early draft had been written in Paris.
