Mercantilism was the dominant school of economic thought throughout the early modern period (from the 16th to the 18th century). This led to some of the first instances of significant government intervention and control over the economy, and it was during this period that much of the modern capitalist system was established. Internationally, mercantilism encouraged the many European wars of the period and fueled European imperialism. Belief in mercantilism began to fade in the late 18th century, as the arguments of Adam Smith and the other classical economists won out.
