They are often referred to as "Mamasok," which means "originals" or "indigenous people." The majority of Kadazan-Dusun tribes claimed they were descended from the Nunuk Ragang people.
This is Sabah's main ethnic group, comprising mainly of paddy rice and hill rice cultivators. Their language is part of the Dusunic family and shares an animistic belief structure as well as different traditions and traditions. Their ancient views about the existence of life - that bricks, plants, and rivers are all living beings. They have souls and ghosts that must be appeased on a regular basis by ceremonies. Some of the traditions are less common in modern times, even for certain holidays.
