To a large extent, it was the belief in the primordialist argument of the kinship, historical traditions and homeland of these ethnic groups that encouraged the Hutu to feel their actions were justified. Despite much academic criticism of primordialism, and the development of other ethnic theories such as constructivism and instrumentalism, primordialism is "influential in identifying the enduring strength of ethnic ties and its member's commitment to it".[8] For example, some scholars have argued that the Cold War influenced and instigate this belief in ethnicity and ethnic conflict.
