what constitutes statehood and sovereignty). People who are recognized to be citizens by the government of an unrecognized country may not consider themselves stateless, but nevertheless may be widely regarded as such especially if other countries refuse to honor passports issued by an unrecognized state. While statelessness in some form has existed continuously throughout human history, the international community has only been concerned with its eradication since the middle of the 20th century. In 1954, the United Nations adopted the Convention relating to the Status of Stateless Persons, which provides a framework for the protection of stateless people. Seven years later, the United Nations adopted the Convention on the Reduction of Statelessness. In addition, a range of regional and international human rights treaties guarantee a right to nationality, with special protections for certain groups, including stateless persons. States bound by the 1989 Convention on the Rights of the Child are obligated to ensure that every child acquires a nationality. The convention requires states to implement this provision in particular where the child would otherwise be stateless, and in a manner that is in the best interests of the child. The status of a person who might be stateless ultimately depends on the viewpoint of the state with respect to the individual or a group of people. In some cases, the state makes its view clear and explicit; in others, its viewpoint is harder to discern. In those cases, one may need to rely on prima facie evidence of the view of the state, which in turn may give rise to a presumption of statelessness. Stateless nations A stateless nation is an ethnic group or nation that does not possess its own state. The term "stateless" implies that the group "should have" such a state (country). The term was coined in 1983 by political scientist Jacques Leruez in his book L'Écosse, une nation sans État about the peculiar position of Scotland within the British state. It was later adopted and popularized by Scottish scholars such as David McCrone, Michael Keating and T. M. Devine. A notable contemporary example of a stateless nation is the Kurds. The Kurdish population is estimated to be between 30 and 45 million, but they do not have a recognised sovereign state. Members of stateless nations are often not necessarily personally stateless as individuals, as they are frequently recognised as citizens of one or more recognized state(s).
