The global phenomenon that reshaped trade patterns following World War I was the rise of significant economic interdependence and the establishment of international organizations aimed at promoting trade. The aftermath of the war accelerated globalization, as countries sought to rebuild and stimulate their economies through increased trade relations. The League of Nations and eventual establishment of organizations like the International Monetary Fund and World Bank aimed to foster economic cooperation and prevent conflicts. This period also saw the U.S. emerge as a major economic power, impacting global trade dynamics and encouraging the flow of goods and capital across borders.
