What happened to Louis when he was young that made him fearful of the power of the nobility?

When Louis was young, he witnessed the violent and chaotic aftermath of the Fronde, a series of civil wars in France that pitted nobles against the crown. This experience instilled in him a deep fear of the nobility's power and their potential to challenge royal authority. As a result, he became determined to centralize power and reduce the influence of the nobility in order to prevent any future uprisings. This fear shaped his later policies as king, leading to a more absolute form of monarchy.
