Pre-19th century: early origin and cultural development The Iban people have a rich indigenous historical tradition, passed down primarily through oral literature, written records on
Papan Turai (wooden plaques) and cultural practices. These sources preserve important details about the Iban's historical migration and settlement. A central aspect of Iban identity is their deep connection to their
ancestral homeland, reflected in both their spiritual beliefs and historical narratives. One key site in this regard is
Tembawai Tampun Juah, located in the Segumon region of
Sanggau,
West Kalimantan, Indonesia. According to Iban oral traditions,
Tembawai Tampun Juah is considered the first settlement of the Iban people, symbolising their journey after being separated from their ancestral figures. This site remains culturally and historically significant, embodying the Iban's connection to their land and heritage. In addition to the spiritual significance of
Tembawai Tampun Juah, the Iban trace their geographical origins to the
Kapuas region in
West Kalimantan, specifically the Ketungau tributary, which is traditionally regarded as the birthplace of early Iban leaders and communities. A pivotal figure in the Iban migration narrative is Sengalang Burung, who holds an important place in Iban oral traditions. According to these traditions, Sengalang Burung and his followers initially settled along the Kapuas River in southwestern Borneo. His grandson, Sera Gunting, later led the Iban further westward into the Tiang Laju Range, now part of Sarawak. It is said that at Merakai, a tributary of the Kapuas River, Sengalang Burung convened a council with his followers to plan their migration to Batang Ai, a region that would become a major center of Iban settlement. The historical timeline of the Iban migration has been further supported by the work of
Benedict Sandin (1968), who suggested that the Iban began their migration from the Kapuas Hulu region in the 1550s. The first group of settlers moved into the Batang Lupar area, establishing a community near the Undop River. Over the course of five generations, the Iban expanded their settlements further west, east and north, founding new communities along the Batang Lupar, Batang Sadong, Saribas, and Batang Layar rivers.
Modern linguistic studies, such as those conducted by
Asmah Haji Omar (1981), Rahim Aman (1997), Chong Shin and
James T. Collins (2019), as well as material culture research by M. Heppell (2020), also support the claim that the Iban language and culture have their roots in the upper Kapuas region. These studies trace the development of the Iban people to this area, reinforcing the historical narratives preserved in oral and written forms. The
Brooke administration played a key role in facilitating Iban migration during Sarawak's territorial expansion, which helped establish the Iban as a dominant ethnic group in the region.
James Brooke, a British adventurer, arrived in Borneo in 1838 at the request of the
Sultan of Brunei to suppress a rebellion. After his success, he was appointed
Rajah of Sarawak in 1841, where he focused on controlling piracy and regulating indigenous practices like
headhunting, which were common among the
Dayak groups, including the Iban. Brooke's most significant opposition came from
Rentap, a prominent Dayak leader. Brooke led three military expeditions against Rentap, culminating in Rentap's defeat at the Battle of Sadok Hill. Throughout these campaigns, Brooke relied heavily on local Dayak soldiers, famously stating, "Only Dayaks can kill Dayaks," underscoring both his dependence on local fighters and the complex dynamics of colonial military alliances. In 1851, Brooke faced accusations of excessive force against the Dayak people, allegedly under the pretext of anti-piracy operations. This led to a
Commission of Inquiry in 1854, which cleared him of any wrongdoing. Despite the controversy, Brooke continued to employ Dayak soldiers in various military campaigns, against the Chinese-led uprising of
Liu Shan Bang and local Malay resistance movements led by
Syarif Masahor. By 1870, large populations of Iban were reported to have established settlements along the
Oya and
Mukah Rivers. In the early 20th century, Iban migration extended further to regions such as
Tatau,
Bintulu (formerly Kemena),
Balingian and the northern parts of Sarawak, including the Limbang River and Baram Valley.

Baleh tributary of the Rejang River in 1922, the establishment of Iban communities in the Suai,
Niah and
Sibuti regions in 1927, and a government-supported relocation to
Lundu in 1955. Additional migrations occurred in line with government development schemes in the
Second and
Fourth Divisions of Sarawak. The outbreak of
Second World War had a significant impact on the Iban and other indigenous groups in Borneo. Following the
Japanese invasion, indigenous populations, including the Iban and Malay, faced severe mistreatment and massacres, particularly in the
Kapit Division. In response, a force of Dayak fighters, including Iban, was formed to assist the
Allied. Trained by a small team of
US airmen and
Australian special operatives, the Dayak force successfully killed or captured approximately 1,500 Japanese soldiers. They also provided critical intelligence about Japanese-held oil fields. prepares a human scalp above a container of human body parts. In the post-war period, during the
Malayan Emergency (1948–1960), the
British Army enlisted Iban personnel to assist in counterinsurgency operations against the
Malayan National Liberation Army (MNLA). These individuals, often with extensive local knowledge and experience as trackers, were attached to British patrols to help navigate the difficult terrain. The involvement of the Iban in these operations became controversial when, in 1952, photographs were published by
The Daily Worker (a British communist newspaper) showing Iban personnel and British soldiers posing with severed heads of suspected insurgents. Initially, the British government denied any official sanction for such practices. However, Colonial Secretary
Oliver Lyttleton later confirmed that Iban troops had been authorized to engage in these actions as part of their military role. The incident led to the
British Malayan headhunting scandal, which attracted widespread criticism. After the conclusion of the conflict, all Dayak troops, including the Iban, were disbanded. ==Ibanic regional groups==
