The Soviet westward offensive of 1918–1919 was part of the campaign by Soviet Russia into areas abandoned by the Ober Ost garrisons that were being withdrawn to Germany following that country's defeat in World War I. The initially successful offensive against the Republic of Estonia ignited the Estonian War of Independence which ended with the Soviet recognition of Estonia. Similarly, the campaigns against the Republic of Latvia and Republic of Lithuania ultimately failed, resulting in the Latvian–Soviet Peace Treaty and Soviet–Lithuanian Peace Treaty respectively. In Belarus, the Belarusian People's Republic was conquered and the Socialist Soviet Republic of Byelorussia proclaimed.

The campaign eventually became bogged down, leading to the Estonian Pskov Offensive, the White Russian Petrograd Offensives, the Lithuanian–Soviet War, the Latvian War of Independence and the continuation of the Ukrainian–Soviet War.
