The World Trade Organization came into existence with the development of international trade and international trade law. Approximately in the last 65 years, international trade has developed due to the latest trend, which has been adopted by many countries in the world to exclude the protectionist domestic legislations while promoting the free exchange of goods. When it is analyzed, the main reason behind the protectionism was the Great Depression between 1929 and 1939, which was followed by many international treaties, new economic and legal strategies that would ease and alter the effect of major protective trade legislations.
During World War II, the countries who fought against Germans, Japanese, Italians formed an organization called United Nations which was a replacement of the League of Nations which was also formed as a result of the World War I. United Nations’ new notion was to encourage economic development and liberalization. In the following years, the United Nations was executing it plans to establish three fundamental international organizations; International Monetary Fund (IMF), the International Bank for Reconstruction and Development (World Bank) and International Trade Organization. General Agreement on Tariffs and Trade was declared instead of establishing the International Trade Organization.
