Mercantile nations are countries that prioritize the accumulation of wealth through trade and commerce, particularly during the 16th to 18th centuries. This economic strategy is rooted in mercantilism, which emphasizes the importance of a favorable balance of trade, state intervention in the economy, and the establishment of colonies to secure resources and markets. Mercantile nations sought to enhance their power and influence by controlling trade routes and resources, thus laying the groundwork for modern capitalism.
