The formation of the League of Nations (League) was the first attempt ever to regulate and to bind the legal relationships among the different members of the international community. The original thirty-two countries that agreed to be bound by the Covenant of the League of Nations (Covenant) wanted to ensure that the League was only a concert of independent states and not a federal union. The League did not aim at establishing a supranational government. The insertion of a withdrawal clause in the very first article of the Covenant contained a manifestation that the League was not intended to be an eternal association of sovereign states.
