The Bretton Woods Conference, officially known as the 'United Nations Monetary and Financial Conference', was a gathering of delegates from 44 nations that met from 1-22 July, 1944 in Bretton Woods, New Hampshire (USA), to agree upon a series of new rules for the post-World War II international monetary system.
The two major accomplishments of the conference were the creation of the International Monetary Fund (IMF) and the International Bank for Reconstruction and Development (IBRD) or the World Bank.
IMF and IBRD are also called 'Bretton Woods twins' because both are set up under the Bretton Woods Conference.
