One change that Cardinal Richelieu made to the French government after Louis XIII took power was centralizing authority in the monarchy. Richelieu implemented policies that strengthened the power of the King and reduced the influence of the nobility and regional parliaments. He created a network of royal officials who reported directly to the King, bypassing traditional power structures. Richelieu's centralization of authority helped to consolidate the power of the French monarchy and establish the absolute authority of the King.
