Step-by-step explanation:
The goals of mercantilism were to increase the wealth of the government (accumulate gold and silver) by controlling economic affairs, and ultimately increasing the power of the nation (both economic and military). You must remember that mercantilism was popular during the 17th and 18th century when democracy didn't exist, and the Kings and Queens were eager to increase their personal wealth, power and greatness.
