Louis XIV, known as the Sun King, attempted to rule France as an unlimited ruler during his reign from 1643 to 1715. He centralized power in the monarchy, famously stating, "L'État, c'est moi" ("I am the state"), and diminished the influence of the nobility through various reforms and the establishment of a strong administrative system. His reign is often associated with the absolute monarchy and the construction of the lavish Palace of Versailles as a symbol of his power.
