A stateless nation is an ethnic group, religious group, linguistic group or other cohesive group which is not the majority population in any nation state. The term implies that the group "should have" such a state, and thus expresses irredentism. This is orthogonal to statelessness in the sense of an individual's complete lack of a legal nationality: members of stateless ethnic groups may be citizens/nationals of the country in which they live, or they may be denied citizenship by that country. Stateless nations are usually not represented as a nation in international sports such as FIFA, Olympics or in international communities such as the United Nations. Nations without state are classified as fourth world nations.
