The Doctrine of Discovery is a policy enacted initially by the 15th-century Catholic Church proclaiming the right of Christian nations to take possession of the lands of non-Christians in the interest of saving their souls. Non-Christians were not recognized as legitimate landowners, and any lands 'discovered' by Christian explorers were claimed as the property of the discoverers' nation.
