The second Peace of Riga takes effect ending the Polish-Soviet War. In the aftermath of the war, the Poles gained land previously held by the Soviets. Prior to the outbreak of WWII, the Soviets refused to enter into an alliance with Britain and France without guaranteed passage through Poland to allow access to mainland Europe, in the event of a war. The Poles, due to anxiety about a Soviet presence in their territory, denied the USSR access. This denial helped to foil any alliance between the three nations. The treaty became null after the Soviet’s invaded Poland on September 18, 1939. [From MHQ—The Quarterly Journal of Military History]
