In the aftermath of the Russian Revolution of 1917, Latvia declared its independence on November 18, 1918. After a prolonged War of Independence, Latvia and Soviet Russia (the predecessor of the Soviet Union) signed a peace treaty on August 11, 1920. In its "Article 2" Soviet Russia "unreservedly recognises the independence and sovereignty of the Latvian State and voluntarily and forever renounces all sovereign rights (...) to the Latvian people and territory." The independence of Latvia was diplomatically recognised by the Allied Supreme Council (France, Great Britain, Italy, Japan, Belgium) on January 26, 1921. Other states followed the suit. On September 22, 1921 Latvia was admitted to membership in the League of Nations and remained a member until the formal dissolution of the League in 1946. On February 5, 1932, a Non-Aggression Treaty with the Soviet Union was signed, based on the August 11, 1920 treaty whose basic agreements inalterably and for all time form the firm basis of the relationship of the two states.
