Answer:
Mercantilism
Step-by-step explanation:
Mercantilism is a type of economic nationalism. It is the belief that a nation's economic prosperity is an assessment of how much gold or silver it has.
mercantilism is based on the idea that by increasing exports and minimising imports, the wealth and power of a Nation was best served.
By discouraging the buying of foreign products, England grew it's wealth by making its people to only buy products from Britain.
