The idea of international organization has probably been around since the advent of the first governments. From the writings of ancient Greek philosophers, for example, we learn of military alliances and international trading agreements. The early Greek city – states Athens, Sparta and Macedonia once employed a common currency, which required a high degree of international cooperation. According to the stone scripture in Orissa, the three Ancient Tamil Kingdoms of Chera, Chola, and Pandya had an alliance among them against the central and north Indian kingdoms threat. We can say that the congress of Vienna as the earliest modern precedent to today’s International Organisation. The congress of Vienna, a multipurpose IO was created by the European great powers to re establish order and stability on the continent after the Napoleonic Wars. The next important IO was the League of Nations which was established after the First World War. The League of Nations embraced the idea of collective security where international security is directly tied to the security of member states. The UN system was created in 1945 following World War II.
