The United Nations Disengagement Observer Force (UNDOF) was established by United Nations Security Council Resolution 350 on 31 May 1974, to implement Resolution 338 (1973) which called for an immediate ceasefire and implementation of United Nations Security Council Resolution 242.
The resolution was passed on the same day the “Agreement on Disengagement” was signed between Israeli and Syrian forces on the Golan Heights, finally establishing a ceasefire to end the 1973 Yom Kippur War.
