In the colonial era, the Atlantic Ocean served as a highway between Europe, Africa, and the Americas, tying together a network of people, raw materials, finished goods, merchants, and sailors that brought wealth to colonial empires.
Generating wealth for the mother country was first and foremost among the reasons for European colonization in the Americas. During this era, the economic theory of mercantilism suggested that a nation’s power relied on a favorable balance of trade: that is, exporting more than it imported.
Establishing colonies promoted mercantilist goals in two ways: first, the colonies ensured the mother country had a cheap supply of raw materials (timber, sugar, tobacco, furs, just to name a few), and second, the colonies served as a captive market for finished goods (furniture, guns, metal implements). In other words, colonies existed to sell things to the mother country and to buy things from it, and the government made its profit by taxing and imposing customs duties on trade.
