The Ibans are a branch of the Dayak peoples of Borneo. In Malaysia, most Ibans are located in Sarawak, a small portion in Sabah and some in west Malaysia. They were formerly known during the colonial period by the British as Sea Dayaks. Ibans were renowned for practising headhunting and tribal/territorial expansion. In ancient times the Ibans were a strong and successful warring tribe in Borneo. They speak the Iban language.
Today, the days of headhunting and piracy have been replaced with the modern era of globalization and technology. However, many Ibans have retained their heritage and continue to live in traditional houses, longhouses called rumah panjai or rumah panjang.
