Gwardia Ludowa (Polish pronunciation: [ˈɡvardja luˈdɔva]; People's Guard) or GL was an underground armed organization created by the communist Polish Workers Party in German occupied Poland, with sponsorship from the Soviet Union. Formed in early 1942, within a short time Gwardia Ludowa became the largest clandestine fighting force on Polish soil which refused to join the structures of the Polish Underground State loyal to the government-in-exile based in London. In the January 1 of 1944 GL was incorporated into the communist Armia Ludowa.
