Acting under Chapter VII of the United Nations Charter, the Council authorised the establishment of a multinational force in Liberia to support the implementation of the 17 June ceasefire agreement.[4] At the same time, it would maintain security following the departure of President Charles Taylor and the installation of a successor authority; create conditions for disarmament, demobilisation and reintegration activities and the delivery of humanitarian aid; and prepare for the deployment of a long-term peacekeeping force (later known as the United Nations Mission in Liberia) by 1 October 2003.[5]
