The term "Kadazandusun" was conscientiously debated and unanimously passed at the 5th KCA Delegates Conference (November 4th & 5th, 1989), as the best alternative approach to resolve the "Kadazan" or "Dusun" identity crisis that had crippled and impeded the growth and development of the Kadazandusun multi-ethnic community socio-culturally, economically and politically ever since the Kadazanism versus Dusunism sentiment was politicized in the early 1960's. With combined self and collective confidence and determination, there is every reason for the Kadazandusuns to succeed in finally establishing a common cultural identity for a united, cooperative and progressive community. For at last (even as we are multi-ethnic), we have found a unifying sense of dignity and brotherhood in the reference to ourselves as Kadazandusuns, which means: Divinity in Humanity.
The Kadazandusun Cultural Association's (KDCA) constitution, Article 6 (1) defines the Kadazandusuns as the definitive indigenous peoples of Sabah comprising the following dialectical ethnic groups:
and persons whose mother tongue is any of the above dialect and who habitually practices and expresses the traditions, custom and other cultural manifestations of the same.
