The United Nations was created to ensure that governments of major countries around the world would continue to actively fight against the axis powers in World War Two. The United Nations was formally revealedÂ after the president of the United States, Franklin D. Roosevelt, declared it on January 1st, 1942.
The United Nations was designed to intervene only in serious matters around the world, serving as a global council. Before the United Nations, there was a similar organization called the League of Nations that was formed shortly after the First World War. However, that was a temporary organization, while the United Nations has continued to operate since its inception.
