The Latvian War of Independence, sometimes called the Latvian War of Liberation was a series of military conflicts in Latvia between 5 December 1918, after the Republic of Latvia proclaimed its independence in 18.11.1918, and the signing of the Treaty of Riga between the Republic of Latvia and the Russian SFSR on August 11, 1920.

The war involved Latvia (its provisional government was supported by Estonia,Poland, and the Western Allies, particularly the United Kingdom) against the Russian SFSR and the Bolsheviks' short-lived Latvian Socialist Soviet Republic. 

Germany and the Baltic nobility added a new level of intrigue, initially being nominally allied to the Nationalist/Allied force, but attempting to jockey for German domination of Latvia. Eventually, the tensions flared up after a German coup against the Latvian government and led to open war.

Following a ceasefire, the Germans developed a ploy, nominally dissolving into the West Russian Volunteer Army led by general Pavel Bermont-Avalov. The West Russian Volunteer Army included Germans and former Russian prisoners of war nominally allied with the White Army in the Russian Civil War, but both Bermondt-Avalov and von der Goltz were more interested in eliminating the nationalists than fighting the Bolsheviks. Certain episodes of the Latvian Independence War are therefore also considered by Polish historians to be a part of the Polish-Soviet War(particularly the Battle of Daugavpils).
