paragraph_text: European justifications for colonization
  
  From the 15th to the 19th centuries, European powers used a number of rationales for the colonization of newly encountered lands populated by indigenous peoples. These included a duty to spread the Gospel to non-Christians, to bring civilization to barbarian peoples, a natural law right to explore and trade freely with other peoples, and a right to settle and cultivate uninhabited or uncultivated land which they considered terra nullius ("no one's land").
  
  Robert J. Miller, Jacinta Ruru, Larissa Behrendt and Tracey Lindberg argue that European powers rationalized their colonization of the New World by the discovery doctrine, which they trace back to papal decrees authorizing Spain and Portugal to conquer newly discovered non-Christian lands and convert their populations to Christianity. Kent McNeil, however, states, "While Spain and Portugal favoured discovery and papal grants because it was generally in their interests to do so, France and Britain relied more on symbolic acts, colonial charters, and occupation." Benton and Strauman argue that European powers often adopted multiple, sometimes contradictory, legal rationales for their acquisition of territory as a deliberate strategy in defending their claims against European rivals.
