One day prior to the signing of the Addis Ababa Agreement, the United Nations Security Council passed Resolution 814, which marked the transfer of power from UNITAF to UNOSOM II, a United Nations led force. The major change in policy that the transition from UNITAF to UNOSOM II entailed is that the new mandate included the responsibility of nation-building on the multinational force. On 3 May 1993, UNOSOM II officially assumed command, and on 4 May 1993 it assumed responsibility for the operations.
