A history of free trade or general trade would include the earliest concepts of exchange and barter of products and services.
The concept of free trade developed over time, and in its modern sense, from the commercial culture of England, and more broadly Europe, in the past five centuries. The earliest free trade theorists were David Ricardo and Adam Smith.
Nations which have adopted free trade policies have generally profited more than isolationist nations, though wars or spending policies, partly affected by liberalized markets associated with free trade, have obscured the gains.
Freetrade is the absence of artificial (government-imposed) barriers to trade among individuals and firms in different nations.
International trade is often constricted by different national taxes, other fees imposed on exported and imported goods, as well as non-tariff regulations on imported goods; theoretically, freetrade is against all these restrictions.
Historically, the freetrade movement was skeptical and even hostile to the notion of intellectual property, regarded as monopolistic and harmful to a free, competitive economy.
Freetrade is the untaxed flow of goods and services between countries, and is a name given to economic policies and parties supporting increases in such trade.
Freetrade supporters argue that all countries have the right to opt out of the world market through isolationism and that companies are fictional persons who are taxed without representation and that the balance of power should shift away from the governments that exploit them.
Freetrade, then, creates an economic incentive for a race to the bottom in regulatory institutions; countries with lax, lenient, non-enforced, or selectively enforced regulatory legal structures will have a competitive advantage in attracting investment to their countries, and not merely in wages.
