An international online summit on Sunday 13 September 2020 commemorates the work of Dag Hammarskjöld, UN Secretary-General, 1953-1961—a global champion for the fair treatment of colonised and emerging states. Academics and political leaders based in Europe, the United States, West Papua, the Pacific and Africa will honour Mr Hammarskjöld’s inspiring leadership and work on decolonisation, in particular his work for the emerging state of West Papua, and his principle of ‘a peoples right of sovereignty over their land’.
