History of the United Nations

[2] The predecessor of the UN, the League of Nations, was conceived after World War I, and established in 1919 under the Treaty of Versailles "to promote international cooperation and to achieve peace and security."

At the subsequent meeting of the Inter-Allied Council in London on 24 September 1941, the eight governments in exile of countries under Axis occupation, together with the Soviet Union and representatives of the Free French Forces, unanimously adopted adherence to the common principles of policy set forth by Britain and United States.

[7][8] President Roosevelt first suggested using the name United Nations, to refer to the Allies of World War II, to Prime Minister Churchill during the latter's three-week visit to the White House in December 1941.

[9] Churchill agreed and cited Lord Byron's use of the phrase "United Nations" in the poem Childe Harold's Pilgrimage, which referred to the Allies at the Battle of Waterloo in 1815.

Having subscribed to a common program of purposes and principles embodied in the Joint Declaration of the President of the United States of America and the Prime Minister of Great Britain dated August 14, 1941, known as the Atlantic Charter,

This declaration omitted any discussion of the potentially-controversial establishment of a permanent peacekeeping force after the war; instead, its stated aim was simply the creation "at the earliest possible date of a general international organization."

He went public with strong advocacy in the 1944 presidential campaign, and turned detailed planning over to the State Department, where Sumner Welles and Secretary Cordell Hull worked on the project.

Stalin insisted on having a veto and FDR finally agreed; thus avoiding the fatal weakness of the League of Nations, which had theoretically been able to order its members to act in defiance of their own parliaments.

[26] Brazil, Syria and a number of other countries qualified for membership by declarations of war on either Germany or Japan in the first three months of 1945 – in some cases retroactively.

The heads of the delegations of the four sponsoring countries invited the other nations to take part and took turns as chairman of the plenary meetings: Anthony Eden, of Britain, Edward Stettinius, of the United States, T. V. Soong, of China, and Vyacheslav Molotov, of the Soviet Union.

The United Nations has achieved considerable prominence in the social arena, fostering human rights, economic development, decolonization, health and education, for example, and interesting itself in refugees and trade.

G. J. Eddy Gouraige argues that UN resolutions from 1946 to 1960 made decolonization a top priority, and gave the General Assembly tools to end colonialism.

[33] During the course of the war, 22 nations contributed military or medical personnel to UN Command;[33] although the United States led the UNC and provided the bulk of its troops and funding, all participants formally fought under the auspices of the UN,[35] with the operation classified as a "UN-led police action".

Duty officers from both sides of the Joint Security Area (commonly known as the Truce Village of Panmunjom) conduct daily communications checks and have the ability to engage face-to-face when the situation demands.

Following the end of the Cold War, renewed calls arose for the UN to become the agency for achieving world peace and co-operation, as several dozen active military conflicts continued to rage across the globe.

Up to the late 1980s, peacekeeping missions were operated by six officials in the United Nations Office of Special Political Affairs, which was headed first by Under-Secretary-General Ralph Bunche, and subsequently Brian Urquhart and Marrack Goulding.

[43] The Department of Peacekeeping Operations was created in March 1992 when Boutros Boutros-Ghali took office as Secretary-General of the United Nations; its creation was one of his first decisions.

[44] In organisational terms, it upgraded and expanded upon the work of the previous Field Administration and Logistics Division (FALD) (which remained active as a subordinate department).

The role of the DPKO, however, wasn't clarified until June 1992, when Boutrous-Ghali issued An Agenda for Peace, a plan to strengthen the UN's capacity for preventive diplomacy and peacekeeping.

The zone, also known as the Green Line (Greek: Πράσινη Γραμμή, Prasini Grammi; Turkish: Yeşil Hat), stretches for 180 kilometres (112 miles) from Paralimni in the east to Kato Pyrgos in the west, where a separate section surrounds Kokkina.

[49][50][51] San Francisco, where the UN founding conference was held, was favored by Australia, New Zealand, China, and the Philippines due to the city's proximity to their countries.

[53] Prior to the completion of the UN's current headquarters, it used part of a Sperry Gyroscope Company factory in Lake Success, New York, for most of its operations, including the Security Council, between 1946 and 1952.

The UN as a whole has generated a rich assortment of non-governmental organizations and special bodies over the years: some with a regional focus, some specific to the various peacekeeping missions, and others of global scope and importance.
