Once International Trade began to become popular, however, it would be regulated by treaties drawn up between two nations spelling out rules and expectations. Mercantilism was the popular approach used by nations when it came to International Trade. Mercantilism is an economic theory that proposes that the the wealth of a nation depends on it's supply of capital or durable produced goods (often measured in gold bullion - see picture to the left), so the more capital available the richer the nation, and that the global volume of trade never changes. Mercantilism speculates that the government can increase capital with a positive balance of trade (exports minus imports) and increase the positive balance of trade with other nations by encouraging exports and discouraging imports, especially through use of tariffs. The economic
policy based on these ideas is sometimes referred to as the "Mercantile System"(France was one of the nations that wholly embraced Mercantilism - see the picture of 1638 France at the height of Mercantilism).For centuries, most nations had high tariffs and lots of restrictions based on the Mercantile System. In the 19th Century, the idea of Free Trade began to become popular, especially in Britain. Free Trade is an idealized economic theory in which trade of goods and services flows between nations unrestricted by governments. Since that time, the idea of Free Trade has remained considerably popular even up until the Present Day and several treaties have been drawn up in an attempt to create a globally regulated trade structure.
