Recognition at the Margins: States with Limited Recognition, Diplomatic Reversal and the Practice of International Recognition, 1945–2026

Recognition at the Margins examines the recognition by members of the United Nations of eight entities that stand outside the Organization: the State of Palestine, the Republic of Kosovo, the Sahrawi Arab Democratic Republic, the Republic of China (Taiwan), Abkhazia, South Ossetia, the Republic of Somaliland and the Turkish Republic of Northern Cyprus. It asks which members recognise which entities, how that pattern has changed since 1945, and what the pattern reveals about the conditions under which recognition is granted, held and lost.

The study rests on a dataset built for it and published with it: a matrix of the 193 members of the United Nations against the eight entities, each cell coded from documented events and graded by the quality of its evidence, together with an event register of more than five hundred dated acts, registers of comparative, historical and excluded cases, a source ledger and a codebook. Every count in the text can be reconstructed from the dataset. All statements of current status speak as of 10 October 2026.

Five findings emerge. Entities gain recognition in waves tied to moments and lose it singly, through negotiated reversals. Portfolios of recognition are small because the coalitions that recognise each entity are separate. A determined opposing state can reverse recognition at scale, as the Hallstein Doctrine and the campaigns of Beijing, Belgrade and Rabat show. Recognition is not membership: the gate to the United Nations is article 4(2) of the Charter, and the permanent members of the Security Council hold its keys. For a new entrant, recognition follows the consent of a parent state and stalls, fragments or reverses in its absence, while the territorial alternatives of unclaimed land, Antarctica, the high seas and outer space are closed by treaty and by the law of territory.

Further chapters treat presence without membership, recognitions that ended, non-territorial claims, and the claims of the Free Republic of Liberland and the Free Republic of Verdis.
