FOREIGN TRADE
Foreign Trade, the exchange of goods and services between nations. Goods can be defined as finished products, as intermediate goods used in producing other goods, or as agricultural products and foodstuffs. International trade enables a nation to specialize in those goods it can produce most cheaply and efficiently.

The objective of an empire was to acquire as much wealth as possible in return for as little expense as possible. This from of international trade, called mercantilism, was commonplace in the 16th and 17th centuries.
International trade began to assume its present from with the establishment of nation-states in the 17th and 18th centuries. Heads of state discovered that by promoting foreign trade they could mutually increase the wealth, and thus the power, of their nations. During this period new theories of economics, in particular of international trade, also emerged.
