How did a move toward mercantilism strenthen royal power?

The move toward mercantilism strengthened royal power by allowing monarchs to control trade and economic resources, thereby increasing their wealth and influence. By imposing regulations, tariffs, and monopolies, kings could ensure that the economy served the interests of the state, reducing the power of rival factions, such as merchant guilds and local nobility. This centralized economic control provided the financial means to support a standing army and expand territories, further consolidating royal authority. Overall, mercantilism aligned economic interests with state power, reinforcing the monarchy's dominance.
