East Kalimantan has a total area of 127,346.92 square kilometres (49,168.92 sq mi)[9] and is the third least densely populated province in Kalimantan (after North Kalimantan and Central Kalimantan).[10] The majority of the region shares a maritime border to the east with West Sulawesi and Central Sulawesi; its Cape Mangkalihat separates the Makassar Strait from the Celebes Sea. Its former northernmost region was split off on 25 October 2012 and is now North Kalimantan; meanwhile it still shares land border to the west with West Kalimantan and Central Kalimantan; to its south, East Kalimantan borders South Kalimantan. The province bordered Sabah before the split, but still have a short border with Sarawak, Malaysia through Mahakam Ulu Regency.
Since 2013, East Kalimantan is now divided into seven regencies and three cities. The proposed capital city of Indonesia, Nusantara, is currently constructed entirely within the province.

Prehistory
East Kalimantan was once mostly covered by tropical rainforest. In prehistoric times, there was limestone cave called Lubang Jeriji Saléh located in the Sangkulirang-Mangkalihat Karst in the district of Bengalon, East Kutai, believed to contain one of the oldest figurative art in the world.[12] The cave paintings were first spotted in 1994 by the French explorer Luc-Henri Fage and the French archaeologist Jean-Michel Chazine, from Kalimanthrope.[13] In 2018, a team of scientists investigating the cave, led by Maxime Aubert from Griffith University and Pindi Setiawan from the Bandung Institute of Technology, published a report in the journal Nature identifying the paintings as the world's oldest known figurative art.[14][15] The team had previously investigated cave paintings in the neighbouring island of Sulawesi.[16] In order to date the paintings, the team used dating techniques on the calcium carbonate (limestone) deposits close to them.[11][17]
4th to 17th centuries
East Kalimantan has been home to several kingdoms, such as the first and oldest Hindu kingdom of Indonesia, the Kingdom of Kutai Martadipura founded in the 4th century CE. It was succeeded by the Sultanate of Kutai ing Martadipura in the 14th century. Other kingdoms were also located in East Kalimantan, such as the Sultanate of Pasir. East Kalimantan region includes Pasir, Kutai, Berau and also Karasikan (Buranun / pre-Sultanate of Sulu) claimed as conquered territory Suryanata Maharaja, the governor of Majapahit in the State Dipa, located in the Great Temple in Amuntai, until 1620 in the Sultanate of Banjar. However, in the Chinese History Annals, Ming shi 明史, at 1417, some parts of the eastern Kalimantan were recorded as a kingdom under the rule of the Philippine kingdom of then Hindu Sulu, as Kalimantan was ruled by a Sulu monarch named Mahalatu Gelamading (Maharaja Klainbantangan) whose title, Klainbantangan, in Chinese rendering, was named after his territory Kalimantan. At this point in time, Sulu had rebelled against Majapahit rule and had invaded Northeast and East Borneo all the way to the territory of Kalimantan.[18] Between the years 1620–1624, kingdoms in East Kalimantan fell under the influence of the Sultanate of Sultan Alauddin Makassar, before the Bungaya agreement. According to the Hikayat Banjar, the Sultan of Makassar never borrowed land for trade[words missing?] covers an area east and southeast of Borneo to the Sultan Mustain Billah of Banjar when Kiai Martasura sent to Makassar and entered into an agreement with the Sultan Tallo I Mangngadaccinna Daeng I Ba'le 'Sultan Mahmud Karaeng Pattingalloang[clarification needed], who became Mangkubumi and principal advisor to the Sultan Muhammad Said, king of Gowa in 1638–1654 and also in-law of Sultan Hasanuddin, who established the East Kalimantan region as a place to trade for the Sultanate of Makassar (Gowa-Tallo); since then pepole began to arrive from South Sulawesi. However, based on the agreement between the Sultanate of Banjar and the Dutch East India Company (VOC) in 1635, VOC helped Banjar restore lands in East Kalimantan to the sphere of influence of the Sultanate of Banjar. It was set out in the Bungaya agreement that the Sultanate of Makassar was not allowed to trade up to the east and the north Borneo.
19th to 20th centuries
In accordance with treaties, on January 1, 1817, Sultan Sulaiman of Banjar handed East Kalimantan, Central Kalimantan, part of West and South Kalimantan (including Banjarmasin) over to the Dutch East Indies. On May 4, 1826, Sultan Adam al-wathiq Billah of Banjar reaffirmed the handover of these territories to the Dutch East Indies colonial administration. In 1846, the Dutch began to put a Resident Assistant in East Borneo at Samarinda (now the province of East Kalimantan and the eastern part of South Kalimantan) named H. Von Dewall. Like all other Indonesian provinces, East Kalimantan was then part of the Dutch East Indies.
East Kalimantan with its then administrative area was established based on the Law No. 25 of 1956, originally only consisted of three regency-level special regions: Berau, Bulongan, and Kutai;[1] and the first governor was APT Pranoto. Three years later in 1959, it oversaw the annexation of Pasir Regency from South Kalimantan into the province, removal of special statuses of other regencies, and creation of Balikpapan and Samarinda as separate municipal cities.[19] Since late 1990s, the number of regencies and cities in East Kalimantan had steadily increased into 14 (with the last creation prior the creation of North Kalimantan, was being Tana Tidung Regency in 2007).
Splitting off of North Kalimantan province
North Kalimantan was formally inaugurated as the 34th province of Indonesia on April 15, 2013. The new province was previously part of East Kalimantan Province.[20]
New national capital
The province will host the future capital city of Indonesia that will be built on parts of Penajam North Paser and Kutai Kartanegara Regency. The future capital is to be named Nusantara,[21] with construction originally projected to start in 2020, and intended to conclude in 2024. However, at a hearing before Committee V of Indonesia's House of Representatives on 9 June 2020, a government representative asserted that the government had not allocated the 2022 budget for the project (for 2022, the ministry proposed a budget worth over 100.46 trillion rupiah - over 7 billion US$ - a steep reduction from the figure of 149.81 trillion rupiah in 2021). Earlier, the National Planning Development Authority had said that the total sum needed to move the capital from its current location in Jakarta to East Kalimantan province amounted to 486 trillion rupiah, of which 265.2 trillion will be mobilised through the public-private partnership (PPP), 127.3 trillion from private special funds, and 93.5 trillion from the state budget. But the Ministry of Finance said that the government switched its priorities to mitigating the effect of the COVID-19 pandemic. The ministry announced that it had not allocated budget for the new capital project. Nevertheless, the new national capital was formally inaugurated in August 2024.

- Agriculture (7.04%)
- Manufacturing (15.05%)
- Other Industrial (7.79%)
- Mining and Quarrying (53.24%)
- Service (16.88%)
East Kalimantan's economy heavily depends on earth resources such as oilfield exploration, natural gas, coal and gold.[25][26] Balikpapan has an oil refinery plant that was built by Dutch governance before World War II, destroyed during World War II, and rebuilt after Indonesian independence.[citation needed]
Other developing economic sectors include agriculture and tourism.[27]
Obstacles to economic development include a lack of transportation infrastructure.[28] Transportation depends on traditional boats connecting coastal cities and areas along main river, Mahakam River.[29]
In 2012, Russia's state railway firm Joint Stock Company (JSC) signed a memorandum of understanding with the East Kalimantan governor over railway lines to transport coal and other freight. The first stage will connect an area near Balikpapan port to West Kutai Regency in a 183-kilometer line and is estimated to cost about $1.8 billion. It will commence in 2013 and by 2017 it is hoped that it carry 20 million tons of coal annually. The second phase will connect a line to Murung Raya in Central Kalimantan with a 60 kilometer line, which will cost an estimated $600 million.[30]
Several oil fields have been discovered in the Mahakam River Delta including Attaka, Badak (1971), Semberah, Nilam, Sanga Sanga, Bekapai (1972), Handil (1974), Samboja, Jakin and Sepinggan.[31][32][33] The Handil, Badak and Bekapai fields are anticline structural traps with oil reservoir sandstones between 450 and 2900 m.[31]: 399 The delta is in the Kutai basin, bounded by the Mankalihat and Paternoster carbonate arch, containing Eocene shales overlain by Oligocene fluvial deposits during marine regression, culminating in the formation of the delta in the late Miocene.[31]: 400
