Nationality is legally recognized connection between an individual and a state. Each state decides on its own which connection with the state is suitable to consider a person its citizen. On the basis of such legally recognized connection and status of a citizen, an individual acquires all rights guaranteed by the legal system of his/her country, and obligations as a correlate of rights. However, there are persons who are not citizens of any state – no state’s laws consider them as their citizens. Due to lack of a country which they could call their own and which would provide them protection, nowhere will they ever be able to access an entire circle of rights offered to citizens. Such persons are stateless.
