History
The coast around Port Moresby is the land of the Motu and Koita peoples. Each year the Motu sailed great lakatoi, multi-hulled canoes with crab-claw sails, west to the Gulf of Papua in the hiri trading voyages, exchanging their clay cooking pots for sago and canoe logs. Further east the islands of Milne Bay were linked by the kula ring, the ceremonial exchange of shell necklaces and armbands made famous by the anthropologist Bronisław Malinowski's work in the Trobriand Islands.
Captain John Moresby surveyed the harbour in 1873 and named it after his father, and London Missionary Society teachers settled among the Motu soon after. Britain proclaimed a protectorate over the southeast of New Guinea in 1884, and the colony of British New Guinea passed to Australia, becoming the Territory of Papua in 1906, run from Port Moresby, with Samarai in Milne Bay as a busy trading port.
In 1942 the region became a front line. Japanese forces landed on the Oro coast and pushed over the Kokoda Track towards Port Moresby before being driven back, while at Milne Bay Australian troops defeated a Japanese landing in August and September. The battles of Buna and Gona on the Oro coast followed at heavy cost. In 1951 the eruption of Mount Lamington in Oro killed about 3,000 people.
Port Moresby became the capital at independence in 1975 and has grown fast since. In Western Province the Ok Tedi copper and gold mine brought revenue and severe pollution of the Fly River system, leading to lawsuits and compensation claims, and the PNG LNG pipeline now crosses the Gulf to a plant near the capital.
