UN Security Council Resolution 733 and UN Security Council Resolution 746 led to the creation of UNOSOM I, the first stabilization mission in Somalia after the dissolution of the central government. United Nations Security Council Resolution 794 was unanimously passed on 3 December 1992, which approved a coalition of United Nations peacekeepers led by the United States. Forming the Unified Task Force (UNITAF), the alliance was tasked with assuring security until humanitarian efforts were transferred to the UN. Landing in 1993, the UN peacekeeping coalition started the two-year United Nations Operation in Somalia II (UNOSOM II) primarily in the south.
