The United Nations

The United Nations is the foundation of international relations. It works towards making peace, security and collaboration between countries. It was formed on 24th October, 1945, due to the aftermath of World War II and today has turned into a global association that deals with a variety of world problems.

Historical Genesis and Evolution

The destruction caused by two world wars highlighted the need for a strong international organization that would be dedicated to ensuring that such a calamity would never happen again. This led to the establishment of the United Nations this followed the League of Nations that was formed in 1919 but was rather ineffective in averting the second world war from happening. The signed nations including China, France, the Soviet Union, the United Kingdom, and the United States among others endorsed the United Nations charter which legally confirmed the institution’s formation on the October 24, 1945.

Principal Organs of the United Nations

The UN’s structure is anchored by six principal organs, each fulfilling distinct roles within the organization:

1. General Assembly

Consisting of all 193 countries willing to participate, the General Assembly serves as the core of the United Nations within which every member of the Assembly gets to discuss a varying international issue and gets to vote as well. It is also the organ where multilateral discussions in respect to international issues take place. Every year, the Assembly conducts General sessions but if an issue demands particular attention, a special session may also be held.

2. Security Council

The core duty of the Security Council is to be responsible for sustaining global peace along with peace in states. To maintain international safety, sanctions can also be placed. The Security Council has fifteen members, out of which five (I.e. China, France, United Kingdom, Russia, and The United States) have special powers as permanent members with veto rights and ten on a rotating basis for a period of two years.

3. Economic and Social Council (ECOSOC)

ECOSOC is best known to be the very center for facilitating and supporting debates revolving around international and global social and economic challenges along with developing policy expectations. In a number of areas like human rights, social welfare, ECOSOC coordinates and supervises other international entities such as regional organizations and national ones by establishing several committees and commissions.

4. International Court of Justice (ICJ)

In addition to being referred to as the World Court ICJ, this court adjudicates legal disputes put forward by different states and even gives out opinions on international legal issues. ICJ is also the principal judicial body of the United Nations and can be found in The Hague, Netherlands.

5. Secretariat

Instead, the Secretariat implements the tasks assigned by either the General Assembly or the Security Council or the Economic and Social Council. Composed of international personnel serving in different capacities, this office is headed by the Secretary-General whose role is to ensure that the multitude of activities of the United Nations is properly executed.

6. Trusteeship Council

The primary function of the Council had been to oversee the administration of trust territories and prepare them for self-rule or independence but now this council suspended its activities on the 1st of November, 1994, after having fulfilled its objectives.

Achievements and Challenges

The United Nations has successfully assisted humans in getting independence through the process of colonization and also promoted human rights by setting international standards through the establishment of different aids to various countries. On another note, the United Nations has been at the front during global health emergencies but the organization has faced criticism in regards to the inefficiency of its bureaucracy and resolution enforcement.

Regardless of the challenges, The United Nation continues to act as a democratic international organization representing all its member states and working towards a goal of world peace through various forums and advanced initiatives available to them.
