A stateless person is someone with no citizenship or nationality. It may be because the state that gave their previous nationality has cease to exist and there is no successor state, or their nationality has been repudiated by their own state, effectively making them refugees. People may also be stateless if they are members of a group which is denied citizen status in the country on whose territory they are born, if they are born in disputed territories, if they are born in an area ruled by an entity whose independence is not internationally recognized, or if they are born on territory over which no modern state claims sovereignty.
