This article provides a comprehensive list of countries, dependencies, political and territorial entities, anarchist regions, autonomous areas and provisional governments that existed for five years or less. These short-lived entities emerged and disappeared under a variety of circumstances. In some cases, newly established states were overthrown by coups, while others were formed during failed revolutionary movements. Additionally, some entities were created as puppet states during wartime or existed as provisional governments. The diverse nature of these political formations reflects the complexity of state formation and dissolution in times of rapid political change.
