List of wars involving Latvia

This is a list of wars that the Republic of Latvia has participated in throughout its history as a duchy (1561–1795) and as a modern-day republic (1918–1940; 1990–present-day)

This list doesn't include the Latvian Soviet Socialist Republic since according to the theory of state continuity of the Baltic states, the republic of Latvia existed as a de jure sovereign state from 17 June 1940 to 4 May 1990^{[citation needed]} and was represented by the Latvian Diplomatic Service, which controlled limited state functions during its occupation. Latvia did not engage in warfare during this period.^{[citation needed]}
