A settler is a person who moves to a new place with the intention of living there permanently. They are generally from a sedentary culture, as opposed to nomadic peoples who may move settlements seasonally, within traditional territories. A settler who migrates to an area previously uninhabited or sparsely inhabited may be described as a pioneer. However, most of the time in history, settlers are people who travel to a land that already belongs to someone else, forcing them out, and claiming the land as their own. The process by which Indigenous territories are settled by foreign peoples is usually called settler colonialism.
Settlement sometimes relies on dispossession of already established populations within the contested area, and can be a very violent process. Sometimes settlers are backed by governments or large countries. Settlements can prevent native people from continuing their work. In Canada, the term settler is currently used to describe "the non-Indigenous peoples living in Canada who form the European-descended sociopolitical majority," asserting that.
