The United Nations Organization (UNO) or simply United Nations (UN) is an international organization whose stated aims are facilitating cooperation in international law, international security, economic development, social progress, human rights, and achievement of world peace. The UN was founded in 1945 after World War II to replace the League of Nations, to stop wars between countries, and to provide a platform for dialogue. It contains multiple subsidiary organizations to carry out its missions.
The Charter of the United Nations is the foundational treaty of the UN. Some of the principles of the UN Charter are; the association principle, the hierarchy principle, the collective security principle, the regional principle, the mediation principle, the trusteeship principle the judicial principle and the collective security principle.
To be a part of UN, the country either a member or not, should be peace-loving, because, if one of the countries would try to begin hostilities between the UN members or other countries, the purpose of the UN would be marred.
Every country has its own dominance about some topics and according to that the UN have made some countries have more important ubiety than others. By this idea the hierarchy principle has been emerged.
One of the aims of the UN is unlimited growth and prosperity for all and the economic and social council is trying to solve countries’ problems by the help of its seventeen agencies. Some examples are Food and Agriculture Organization (FAO), United Nations Educational, Scientific and Cultural Organization (UNESCO) and International Atomic Energy Agency (IAEA).
The charter decided that the nations should not form other organizations between them, because this could impair the association between the members of UN.
Another important aim of the UN is to keep the peace between the adversaries and help them to solve their problems by acting as the mediator.
The United Nations Trusteeship Council, one of the principal organs of the United Nations, was established to help ensure that non-self-governing territories were administered in the best interests of the inhabitants and of international peace and security. The trust territories – most of them former mandates of the League of Nations or territories taken from nations defeated at the end of World War II – have all now attained self-government or independence, either as separate nations or by joining neighbouring independent countries. The last was Palau, which became a member state of the United Nations in December 1994.
The judicial principle’s main functions are to settle legal disputes submitted to it by states and to give advisory opinions on legal questions submitted to it by duly authorized international organs, agencies, and the UN General Assembly.
Collective security can be understood as a security arrangement in which all states cooperate collectively to provide security for all by the actions of all against any states within the groups which might challenge the existing order by using sanctions and force. While collective security is possible, several prerequisites have to be met for it to work.
