When Louis XIV came of age to rule how did he ensure that he had supreme power?

When Louis XIV came of age to rule, he asserted his supreme power by centralizing authority and diminishing the influence of the nobility. He famously proclaimed, "L'état, c'est moi" ("I am the state"), emphasizing his belief in absolute monarchy. To reinforce his control, he established a lavish court at Versailles, where he could keep the nobility occupied and dependent on his favor, effectively curtailing their power. Additionally, he promoted a bureaucratic system that relied on loyal officials, ensuring that governance remained firmly under his command.
