United Nations Emergency Force

The United Nations Emergency Force (UNEF), which was operational from November 1956 to June 1967, was the first armed United Nations peacekeeping mission. The plans and lessons-learned from UNEF on subjects such as consent, force generation and reimbursement have influenced all subsequent peacekeeping operations.

A second United Nations Emergency Force (UNEF II) was operational between October 1973 to July 1979.

Mandate
UNEF was established by the General Assembly, acting under the Uniting for Peace resolution, in its resolutions 1000 (ES-I) and 1001 (ES-I), to secure and supervise the cessation of hostilities in the Suez.

Blue helmets
UNEF was the first mission in which blue helmets were used to be able to identify peacekeepers from other military forces in the area.
