Enga is one of the provinces in Papua New Guinea (PNG). It is located in the north most region of the highlands of PNG, having been divided from the Western Highlands to become a separate province when the provinces were created at the time of independence in 1975. The people of Enga are called Engans—they are a majority ethnic group—speaking one language in all its five districts: approximately 500,000 people. A small minority of Engans' land on the eastern side of the region remained in the Western Highlands, their territory being accessible by road from Mount Hagen but not directly from elsewhere in Enga territory. History Europeans—typically Australian gold prospectors—originally entered what is now Enga province from the east in the late 1920s, although the best-known exploration of Enga took place during the early 1930s when Mick Leahy and a party of men travelled from what later became Mount Hagen to the site of the future Wabag and then south through the Ambum Valley to what later became East Sepik. Culture Engans are divided into three subgroups, the Mae, the Raiapu, and the Kyaka. Like many other highland Papua New Guineans living west of the Daulo Pass (between Chimbu Province and Eastern Highlands Province), the traditional Engan settlement style is that of scattered homesteads dispersed throughout the landscape. Historically sweet potato was the staple food, sometimes supplemented by pork. The modern diet places an increasing emphasis on store bought rice and tinned fish and meat. Pigs remain a culturally valued item with elaborate systems of pig exchange also known as "tee" that mark social life in the province. The Raiapu practice extensive agriculture in their highland region. Sweet potatoes are the major crop, forming two-thirds of the Raiapu diet. They also raise pigs. The Raiapu Enga believe in a variety of supernatural beings, although anthropologist Richard Feachem states that the Raiapu "derive no joy or comfort from their religious beliefs" due to the pervasively indifferent or malevolent nature of those spirits. The yalyakali, or "sky people," are fair-skinned and beautiful deities whose idyllic lives in the clouds mirror the agricultural and clan structure of the Raiapu below but lack the sadness of ordinary life. They are considered remote and unapproachable by humans. Feachem states that "the remaining spirit beings (ghosts and demons) are an aggressive and bellicose group who are mercilessly engaged in an endless cycle of revenge and mischief."
