How did Cardinal Richelieus actions toward Huguenots and the nobility strengthen the monarchy?

Cardinal Richelieu's actions toward the Huguenots and the nobility significantly strengthened the French monarchy by centralizing power and reducing dissent. He dismantled the political and military power of the Huguenots, notably by besieging their stronghold at La Rochelle, which diminished their influence and ensured greater control for the crown. Additionally, Richelieu curtailed the autonomy of the nobility through the suppression of their military capabilities and by enforcing royal authority, thereby reinforcing the absolute power of King Louis XIII. These measures created a more unified state, consolidating royal power and reducing challenges to the monarchy.
