Papua New Guinea

Historical overview

Papua New Guinea is one of the world’s most culturally and linguistically diverse countries. Its communities have developed distinctive agricultural systems, village governance, customary law, trade routes, artistic traditions and spiritual practices over many thousands of years. Archaeological research at Kuk Swamp in the Western Highlands has documented early agricultural activity, demonstrating the region’s importance in the history of human food production.

The island of New Guinea was divided among European colonial powers. The Netherlands claimed the western portion in the nineteenth century. In 1884, Germany established control over the northeastern region, while Britain declared a protectorate over the southeastern region. Britain annexed the southern territory in 1888, and it was subsequently administered by Australia as the Territory of Papua. DFAFollowing the First World War, Australia administered the former German territory under a League of Nations mandate. During the Second World War, Japanese forces occupied parts of the region, and the New Guinea campaign became a major Pacific theatre of war. The conflict brought severe suffering to local communities, who experienced displacement, forced labour, food shortages and violence. Papua and New Guinea were placed under a combined Australian administration after the war. DFAPolitical organisation and nationalist activity developed during the post-war period. Michael Somare and other leaders helped guide the transition to self-government. Papua New Guinea became self-governing on 1 December 1973 and achieved full independence on 16 September 1975. The Constitution had been adopted by the Constituent Assembly on 15 August 1975 and came into force on independence day. Its National Goals and Directive Principles include integral human development, equality and participation, national sovereignty, resource ownership and the rejection of violence. DFAAfter independence, Papua New Guinea developed a parliamentary constitutional system. However, the country faced difficult challenges involving geography, infrastructure, public services, political competition, resource extraction and regional inequality.

A major conflict developed on Bougainville, beginning in 1988–89, amid opposition to the Panguna copper mine, environmental damage, land disputes and demands for greater local control. The conflict involved armed groups, government forces and civilian communities. The Papua New Guinea Department of Foreign Affairs describes the nine-year revolt as claiming approximately 20,000 lives; this should be presented as an official estimate rather than an independently settled total. A ceasefire was reached in 1997–98, and the Bougainville Peace Agreement was signed on 30 August 2001. DFAThe agreement established three pillars: autonomy, weapons disposal and a referendum on Bougainville’s political status. In December 2019, the referendum produced a 97.7% vote in favour of independence. The result was an important political milestone, but it did not itself immediately make Bougainville an independent state. The outcome requires further consultation and constitutional processes between the Autonomous Bougainville Government and the national government. PEACEBUILDING AND PEACE SUPPORT
