Highland Papua in the context of "New Guinea"

Provinces are the first-level administrative divisions of Indonesia. They were formerly called first-level provincial regions (provinsi daerah tingkat I), before the Reform era. Provinces have a local government, consisting of a governor (Gubernur) and a regional legislative body (Dewan Perwakilan Rakyat Daerah Provinsi, DPRD Provinsi). The governor and members of local representative bodies are elected by popular vote for five-year terms, but governors can only serve for two terms. Provincial governments have the authority to regulate and manage their own government affairs, subject to the limits of the central government. The average land area of all 38 provinces in Indonesia is about 49,800 km (19,200 sq mi), and they had an average population of 7,410,626 people in mid-2024.

Indonesia is divided into 38 provinces, nine of which have special autonomous status. The terms for special status are "Istimewa" and "Khusus", which translate to "special", or "designated". Provinces are further divided into regencies and cities (formerly called second-level region regencies/cities, or kabupaten/kotamadya daerah tingkat II), which are in turn subdivided into districts (kecamatan). Proposals for the creation of additional provinces (by the splitting of existing ones) have been considered by the Indonesian government, but further action has been suspended since 2013 under a moratorium. However, in 2022, nine years later, Central Papua, Highland Papua, South Papua, and Southwest Papua were created and became the youngest provinces in the country. The enactment of the Law on State Capital in 2022 established a future provincial-level city, Nusantara, which would officially become the 39th province after a presidential decree on relocating the state capital is issued, and it would replace Jakarta as the nation's capital city.

The Indonesia–Papua New Guinea border separates the Papua, Highland Papua, and South Papua provinces of Indonesia from the Sandaun and Western provinces of Papua New Guinea. The border, which divides the island of New Guinea in half, consists of two straight north–south lines connected by a short section running along the Fly River, totalling 824 km (512 mi).

Dutch New Guinea or Netherlands New Guinea (Dutch: Nederlands-Nieuw-Guinea, Indonesian: Nugini Belanda) was the western half of the island of New Guinea that was a part of the Dutch East Indies until 1949, later an overseas territory of the Kingdom of the Netherlands from 1949 to 1962. It contained what are now Indonesia's six easternmost provinces, Central Papua, Highland Papua, Papua, South Papua, Southwest Papua, and West Papua, which were administered as a single province prior to 2003 under the name Irian Jaya, and now comprise the Papua region of the country.

During the Indonesian Revolution, the Dutch launched politionele acties to capture territory from the Indonesian Republic. The harsh methods of the Dutch drew international disapproval. With international opinion shifting towards support of the Indonesian Republic, the Dutch managed in 1949 to negotiate for the separation of Dutch New Guinea from the broader Indonesian settlement, with the fate of the disputed territory to be decided by the close of 1950. The Dutch in the coming years stated at the UN that the indigenous population of Dutch New Guinea represented a separate ethnic group from the people of Indonesia and thus should not be absorbed into the Indonesian state. The Indonesian Republic, as successor state to the Netherlands East Indies, claimed Dutch New Guinea as part of its natural territorial bounds. The dispute over New Guinea was an important factor in the quick decline in bilateral relations between the Netherlands and Indonesia after Indonesian independence. The dispute escalated into low-level conflict in 1962 following Dutch moves in 1961 to establish a New Guinea Council.

The Dani (also spelled Ndani) are an ethnic group from the Central Highlands of Western New Guinea in Baliem Valley, Highland Papua, Indonesia. Around 100,000 people live in the Baliem Valley, consisting of representatives of the Dani tribes in the lower and upper parts of the valley each 20,000 and 50,000 in the middle part (with a total of 90,000 people). The areas west of the Baliem Valley are inhabited by approx 180,000, representatives of the Lani people, incorrectly called "Western Dani". All inhabitants of Baliem Valley and the surrounding areas are often called Dani hence they are also sometimes conflated with other highland tribes such as Lani in the west; Walak in the north; Nduga, Mek, and Yali in the south and east.

They are one of the most populous tribes in the highlands and are found spread out through the highlands. The Dani are one of the best-known ethnic groups in Papua, due to the relatively numerous tourists who visit the Baliem Valley area where they predominate. Ndani meaning 'people of the east' is the name given to the Lani living east of the Moni, at the time misunderstood to refer to all inhabitants of the Baliem Valley, and while they call themselves Hubula (or Huwulra, Hugula, Hubla), they have been known as Dani since the 1926 Smithsonian Institution-Dutch Colonial Government expedition to New Guinea under Matthew Stirling who visited the Moni.

The Baliem Valley (Indonesian: Lembah Baliem; also spelled Balim and sometimes known as the Grand Valley) is a valley of the Central Highlands in Western New Guinea, specifically in the province of Highland Papua, Indonesia. The main town in the valley is Wamena, which lies on the Baliem River. The valley is about 80 km in length by 20 km in width and lies at an altitude of about 1,600–1,700 metres (5,200–5,600 ft), with a population of over 200,000.

The discovery of the Baliem Valley to the Western world and the unexpected presence of its large agricultural population was made by Richard Archbold’s third zoological expedition to New Guinea in 1938. On 21 June an aerial reconnaissance flight southwards from Hollandia (now Jayapura) found what the expedition called the "Grand Valley". Flights in later weeks described fenced villages of 3-50 houses, farm fields and drainage ditches. They landed on Lake Habbema 15 miles west. Teams of Dutch soldiers and Dayak people recruited from Borneo collected flora and fauna in the Baliem Valley, but did not know the language and killed one native without firing a warning shot. 10-15 villages formed a neighborhood, within an hour's walk. Several neighborhoods made a confederation, and several confederations made an alliance of 4,000-5,000 people, which was constantly fighting feuds to avenge previous deaths caused by members of other alliances, though all had the same culture, ethnicity and language.

Papua, formerly known as West Irian and Irian Jaya, is a province of Indonesia, comprising the northern coast of Western New Guinea together with island groups in Cenderawasih Bay to the west. It roughly follows the borders of the Papuan customary region of Mamta – Tabi Saireri and is divided into eight regencies (kabupaten) and one city (kota), the latter being the provincial capital of Jayapura.

It is bordered by the nation of Papua New Guinea to the east, the Pacific Ocean to the north, Cenderawasih Bay to the west, and the provinces of Central Papua and Highland Papua to the south. The province also shares maritime boundaries with Palau in the Pacific. Papua, along with the five other Papuan provinces, has a higher degree of autonomy compared to other Indonesian provinces.

Central Papua, officially the Central Papua Province (Indonesian: Provinsi Papua Tengah) is an Indonesian province located in the central region of Western New Guinea. It was formally established on 25 July 2022 from the former eight western regencies of the province of Papua. It covers an area of 61,072.91 km and had an officially estimated population of 1,472,910 in mid 2024 (comprising 784,670 males and 688,240 females). It is bordered by the Indonesian provinces of West Papua to the west, the province of Papua to the north and northeast, by Highland Papua to the east, and by South Papua to the southeast. The administrative capital is located in Wanggar District in Nabire Regency, although Timika (in Mimika Regency) is a larger town. Its traditional name is Mee Pago – Saireri.

Central Papua is bordered by seas to the north and south. Nabire is situated in the northern part of Central Papua, Indonesia. This lowland area is directly adjacent to the Teluk Cenderawasih National Park and boasts immense potential for marine tourism including coral reefs, white sandy islands, and whale sharks in their natural habitat. The southern part of Central Papua is mostly swampy terrain and the location of the port of Amamapare and Timika, the largest town in this province. The central region of Central Papua is dominated by the Jayawijaya Mountains, which encompasses the snow-capped Puncak Jaya, the highest peak in Indonesia. This mountain range is also home to the Grasberg gold mine, operated by Freeport Indonesia.

South Papua, officially the South Papua Province (Indonesian: Provinsi Papua Selatan) is an Indonesian province located in the southern portion of Papua, following the borders of the Papuan customary region of Anim Ha. Formally established on 25 July 2022 and including the four most southern regencies that were previously part of the province of Papua and before 11 December 2002 had been a single larger Merauke Regency, it covers a land area of 117,849.16 km, about the same area as Pennsylvania or Kirov Oblast (or 90% of that of England). This area had a population of 513,617 at the 2020 Census, while the official estimate as at mid 2024 was 542,075 (281,466 males and 260,609 females), making it the least populous province in Indonesia.

It shares land borders with the separate nation of Papua New Guinea to the east, as well as the Indonesian provinces of Highland Papua and Central Papua to the north and northwest, respectively. South Papua also faces the Arafura Sea in the west and south, which is a maritime border with Australia. Merauke is the economic centre of South Papua, while its administrative centre is the town of Salor located in Kurik District of Merauke Regency, around 60 km northwest of Merauke town.
