United Nations Truce Supervision Organisation

The United Nations Truce Supervision Organization (UNTSO) is an organization founded on 29 May 1948 for peacekeeping in the Middle East. Its primary task was providing the military command structure to the peace keeping forces in the Middle East to enable the peace keepers to observe and maintain the cease-fire, and as may be necessary in assisting the parties to the Armistice Agreements in the supervision of the application and observance of the terms of those Agreements. The command structure of the UNTSO was maintained to cover the later peace keeper organisations of the United Nations Disengagement Observer Force (UNDOF) and the United Nations Interim Force in Lebanon (UNIFIL).

In response to a request from Count Folke Bernadotte, United Nations Mediator for Palestine, the Secretary-General of the United Nations, Trygve Lie, sent 50 members of the United Nations guard force from Lake Success to assist the Mediator in supervising the Truce in the former British Mandate of Palestine in 1948 and the "UNTSO", the first peacekeeping operation was established by the United Nations. All the members of the party were experienced international civil servants with a background of service with the United Nations Secretariat at Headquarters. While on duty in Palestine, they were to continue to wear United Nations guard uniforms. UNTSO military observers remain in the Middle East to monitor ceasefires, supervise armistice agreements, prevent isolated incidents from escalating and assist other UN peacekeeping operations in the region. This resolution formed the basis for the establishment of the first United Nations peace-keeping operation which became known as the United Nations Truce Supervision Organization UNTSO In November 1947, the United Nations General Assembly endorsed a plan for the partition of the then British Mandate of Palestine, providing for the creation of an Arab State and a Jewish State, with Jerusalem to be placed in Trusteeship with international status. The plan was not accepted by the Palestinian Arabs and Arab States and only partially accepted by the Jewish Agency of Palestine. On 14 May 1948, the United Kingdom relinquished its mandate over Palestine and the State of Israel was proclaimed. On the following day, the Arab States invaded Palestine Mandate territory.
