Under early mercantilism, european nations sought a to import raw materials from the americas and ship manufactured goods to their colonies

TRUE

I'm assuming you included that as a true/false sort of question.

The mercantile system believed the wealth of the world was a fixed amount, measured primarily in gold and silver accumulated.  The system promoted a nation selling its products abroad but not needing to buy from others, or imposing heavy tariffs if importing anything.  Colonies were created to provide raw materials and resources to the mother country and a market for the mother country's products.  Commerce was heavily controlled by the government through charters granted to specific trading companies.

As one example, Great Britain strove to achieve its mercantilism goal by using the American colonies as a way of enriching the British home government.  Britain also sought to control shipping by a dominant navy and merchant marine.

"Mercantilism" is a term we get from Scottish philosopher Adam Smith (1723-1790).  Smith criticized what he called the "mercantile system" because it restricted trade and thus restricted economic growth.   Smith countered by advocating a free market -- the opportunity for all nations to increase their wealth by exchanging goods freely with one another according to what would become known as capitalist principles.
