Polish Armed Forces in the East (1914–1920)

Polish Armed Forces in the East (Polish: Polskie Siły Zbrojne na Wschodzie, Russian: Вооруженные силы Польши на Востоке) around World War I is a term used for several Polish military formations formed in Russia and operating in the period of 1914–1920 (First World War, Russian Revolution of 1917, and the early stages of the Polish-Ukrainian War and Polish-Soviet War). Early formations were part of the Imperial Russian Army. Later, during the Russian Revolution, the Polish formations were mainly allied to the White Russian forces and the Western powers (both the German Empire and the Entente). All the formations (or their remains) were eventually incorporated into the Polish Army by 1920.
