The chief minister of France or, closer to the French term, chief minister of state (French: principal ministre d'État), or prime minister of France[1] were and are informal titles given to various personages who received various degrees of power to rule the Kingdom of France on behalf of the monarch during the Ancien Régime ('Old Regime').
However, during moments where the king was absent from the country, highly sick, indifferent or unfit to govern, the Chief Minister had a strong role, becoming the real mind behind the state's operating.
From 1661, Louis XIV and his successors refused to allow any one of their ministers to be deemed more important than others, so the term was not in use.
[citation needed] With the eruption of the French Revolution in 1789, the First Minister of State progressively lost importance and influence inside national politics.
Finally, with the coming of the constitutional monarchy in 1791, the title of First Minister ceased to exist.
