List of historical unrecognized states

These lists of historical unrecognized or partially recognized states give an overview of extinct geopolitical entities that wished to be recognized as sovereign states, but did not enjoy worldwide diplomatic recognition. The entries listed here had de facto control over significant claimed territory and were self-governing with a desire for full independence. These formally unrecognized entities emerged and disappeared under a variety of circumstances. In some cases, newly established states were overthrown by coups (e.g., the Republic of Biafra), while others were formed during failed revolutionary movements (e.g., the Mahdist State). Additionally, some entities were created as puppet states during wartime (e.g., Tiso's First Slovak Republic) or existed as provisional governments (e.g., the Provisional Government of Western Thrace). The diverse nature of these political formations reflects the complexity of state formation and dissolution in times of geopolitical uncertainty.
