What political concept involves one nation's dominance over another for the purpose of settlement?

The concept involving one nation's dominance over another for the purpose of settlement is colonialism. Colonialism is characterized by the establishment of control over a foreign territory, often through the migration of settlers and the establishment of new societies in the colonized area. This process typically involves the subjugation and exploitation of the native population, along with the imposition of the colonizer's culture, economy, and governance structures.

In contrast, sovereignty refers to the authority of a state to govern itself without interference from outside powers, while imperialism is broader, encompassing various forms of domination, such as economic and political control, which may not necessarily involve settlement. Mainstream politics relates to common political practices and ideologies in a given society and does not specifically address territorial dominance or settlement.
