The primordialist view suggests that the irreconcilable cultural differences between the Hutu and the Tutsi was the major cause of the Rwandan genocide as it included notions about the right to the homeland and led the Hutu to regard the Tutsi as intruders. Furthermore, in this view, the different cultural identities led to hardened beliefs of "us" and "them", making it easier for the Hutu to dehumanise the Tutsis and thus making the occurrence of mass murder more possible.
