Colonialism is the practice of extending and maintaining political, social, economic, and cultural domination over a territory and its people by another people in pursuit of interests defined in an often distant metropole, who also claim superiority. While frequently an imperialist project, colonialism functions through differentiating between the targeted land and people, and that of the colonizers (a critical component of colonization). Rather than annexation, this typically culminates in organizing the colonized into colonies separate to the colonizers' metropole. Colonialism sometimes deepens by developing settler colonialism, whereby settlers from one or multiple colonizing metropoles occupy a territory with the intention of partially or completely supplanting the existing indigenous peoples, possibly amounting to genocide.
Colonialism monopolizes power by understanding conquered land and people to be inferior, based on beliefs of entitlement and superiority, justified with beliefs of having a civilizing mission to cultivate land and life, historically often rooted in the belief of a Christian mission. These beliefs and the actual colonization establish a so-called coloniality, which keeps the colonized socio-economically othered and subaltern through modern biopolitics of sexuality, gender, race, disability and class, among others, resulting in intersectional violence and discrimination.
