This book purports to examine in-depth the historical evolution of the International Monetary System starting with the “Classical Gold Standard System” that was adopted by various governments around the world between the years of 1880-1914. Following the inception of the “Inter-war Period” which took place between 1918-1939, the Classical Gold Standard System was abandoned. It was only after the post-WWII period that this standard was restored only for a short-period of time until the emergence of the “Bretton Woods System” between 1944-1971 which completely replaced the gold standard sy S. dollar.
