United Nations Operation in Somalia II (UNOSOM II) was the second phase of the United Nations intervention in Somalia, from March 1993 until March 1995. UNOSOM II carried on from the United States-controlled (UN-sanctioned) Unified Task Force (UNITAF), which had in turn taken over from the ineffectual United Nations Operation in Somalia I (UNOSOM I) mission. All three of these interventions were aimed at creating a secure enough environment for humanitarian operations to be carried out in the increasingly lawless and famine-stricken country.
