The Navigation Acts and the Trans-Atlantic trade were all a part of what European economic theory?

Mercantilism

Explanation:

The economic system of trade that lasted from 16th century till 18th century is called Mercantilism. It was based on the concept that a nation's power and wealth were best served by increasing the exports, hence it relied on increasing trade.

It was employed by most countries of western Europe- Portugal, Italy, Spain, France, Netherlands and Germany.

Mercantilist regulations were removed during 18th and 19th century and was replaced by laissez-faire economics and free trade.
