The Mat Salleh Rebellion was a series of major armed disturbances against the British North Borneo Chartered Company administration in North Borneo, now the Malaysian state of Sabah. It was instigated by Datu Muhammad Salleh (also known as Mat Salleh), a local chief from the Lingkabo district and Sugut River. He led the rebellion between 1894 until his death in Tambunan in 1900. The rebellion then continued on for another five years until 1905.
