Explanation:

Bretton Woods Agreement or "Bretton Woods Conference" is the name with which a series of provisions agreed upon by some 45 Allied countries in July 1944 became known, in the same American city that gave name to the agreement in the state of New Hampshire at the Mount Washington Hotel. The purpose of such a concert of nations was to define the parameters that would govern the world economy after World War II.

The financial system that would emerge from Bretton Woods would be largely favorable to the United States, which would henceforth have de facto control of much of the world economy as well as of its entire capital distribution system. The United States finally took the reins of world finance, a maneuver it refused to execute for at least about 25 years, because of US foreign policy principles, which advocated non-involvement in political and economic issues sensitive to European nations.

In short, this conference created a fixed exchange rate system between the United States and most of Europe.
