Settler colonialism is a process by which settlers exercise colonial rule over a land and its indigenous peoples, transforming the land and replacing or assimilating its population with or into the society of the settlers. Assimilation has sometimes been conceptualized in biological terms such as the "breeding of a minority population into a majority," but in other cases, such as in some parts of Latin America, biological mixing of populations was less problematic.
Settler colonialism is a form of exogenous (of external origin, coming from the outside) domination typically organized or supported by an imperial authority, which maintains a connection or control to the territory through the settler's colonialism. Settler colonialism contrasts with exploitation colonialism, where the imperial power conquers territory to exploit the natural resources and gain a source of cheap or free labor. As settler colonialism entails the creation of a new society on the conquered territory, it lasts indefinitely unless decolonisation occurs through departure of the settler population or through reforms to colonial structures, settler-indigenous compacts and reconciliation processes.
