What reason did kings have for thinking that mercantilism was the way to power?

Kings believed that mercantilism was the path to power because it emphasized the importance of accumulating wealth, particularly gold and silver, as a measure of national strength. By promoting exports over imports and establishing colonies, they could enhance their economic influence and secure resources. Additionally, mercantilism encouraged government intervention in the economy, allowing kings to control trade and bolster their authority. This economic strategy was seen as a means to achieve national self-sufficiency and military strength.
