The Kingdom of France in the early present day time frame, from the Renaissance (around 1500– 1550) to the Revolution (1789– 1804), was a government controlled by the House of Bourbon (a Capetian cadet branch).
The period is commanded by the figure of the "Sun King", Louis XIV (his rule of 1643– 1715 being one of the longest ever), who figured out how to kill the remainders of medieval feudalism and set up an incorporated state under a flat out ruler, a framework that would continue until the French Revolution and past.
It would be an "absolute monarchy" that gives all power to one individual for life, since this person usually gains power either through hereditary succession of through violence.
