This memorial for Dag Hammarskjöld and his 1961 Decolonisation Program for West Papua explores a complex global story of two unique UN peace-keeping undertakings in 1961 organised by the UN Secretary-General in the midst of the Cold War. The first inserted a UN peace-keeping military force into the Congo to de-escalate conflict over the new state’s mineral resources. The second was designed to deliver the West Papuans their right of self-determination and prevent Indonesia invading the Non-Self-Governing Territory of Dutch New Guinea. What was the outcome? First, the Secretary-General lost his life. Second, the new state of Congo nose-dived from democracy to authoritarianism. Third, the Non-Self-Governing Territory of Dutch New Guinea (West Papua) was passed to Indonesia, an Asian state on the verge of political and economic collapse. These three stories are told together during this seminar 'West Papua's return to the UN: fulfilling the legacy of UN Sec-General Hammarskjöld'.
