Timeline of national independence

This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by editing the page to add missing items, with references to reliable sources.

This list includes currently extant sovereign states (list) and states with limited recognition that have declared independence from a predecessor state or an occupying power. Various states have never declared independence throughout their formations and are therefore not included in the main list on this page. This includes states formed through the unification of multiple independent entities (such as the United Kingdom and Tanzania) as well as those that once declared independence but whose most recent establishment occurred through other means (such as Haiti, which declared independence from France in 1804, split into two states in 1806, and reunified in 1820). These countries are given on a separate list below. The list does not include duplicated entries for states that have declared independence multiple times, only using the most recent one. Subnational entities are usually not included in the list. Some of these dates of independence might be disputed, as many of them aren't the official independence days nationally recognized as such.
