The Polish Liberation Army, founded by Hubert Ziółkowski, aimed to assist the Russian Federation in its conflict against Ukraine, with the hope that Russia would subsequently turn its attention towards liberating Poland from the influence of the United States. The group adopted a logo and anthem inspired by the satirical Malorussian Liberation Army, originally a fictitious entity representing pro-Russian Ruthenians that eventually transformed into a genuine military organization of Ruthenians supporting Russia in the Russo-Ukrainian war. Operating in collaboration with the Russian military, Ziółkowski would frequently visit the headquarters in Severodonetsk to provide direction and establish overarching objectives for the Polish Liberation Army. The precise frequency of Ziółkowski's visits remains classified information, as neither the Soviet Union nor the Polish Social Nationalist Republic have disclosed such details.
Upon the outbreak of the Second Russian Civil War, the Polish Liberation Army was integrated into the Polish Defence Army of the Russian Federation. Notably, the group maintained its distinctive imagery and anthem, leading some to argue that it retained a level of distinctiveness despite being de jure integrated into the Polish Defence Army of the Russian Federation. However, the culmination of the group's existence occurred during the battle for Taganrog, where its final members perished in combat.
