Union of Armed Struggle
underground army formed in Poland following its invasion by Germany that opened World War II (1939–1942)
The Union of Armed Struggle (Polish: Związek Walki Zbrojnej; ZWZ), also translated as the Union for Armed Struggle, Association of Armed Struggle, and Association for Armed Struggle, was a resistance-movement underground army that was formed in Poland following the country's September 1939 invasion by Germany and the Soviet Union that set off World War II. The ZWZ existed from 13 November 1939 until 14 February 1942, when it was renamed the Home Army (Armia Krajowa, or AK).
History
The ZWZ had been created from an earlier organization, Służba Zwycięstwu Polski, or SZP (the Service for Poland's Victory), which had been founded in September 1939 by General Michał Tokarzewski-Karaszewicz.
In January 1940 the ZWZ was split in two:
the area under German occupation — led by Colonel Stefan Rowecki, headquartered in Warsaw; and
the area under Soviet occupation — led by General Karaszewicz-Tokarzewski, headquartered in Lwów.
Formally the Union of Armed Struggle was commanded from Paris by General Kazimierz Sosnkowski (nom de guerre Józef Godziemba), who after Poland's defeat had escaped to France via Hungary. Due to practical difficulties, however, Sosnkowski's control of the organization was very limited. Accordingly, in instructions that reached Warsaw on 4 December 1939, he ordered his subordinates to create regional branches of the ZWZ, which was to be a national military organization without regard to political affiliations or social standing. Sosnkowski and his staff also posited that, upon the entry of regular Polish army units, a national uprising would take place.
After the fall of France on 18 June 1940, General Władysław Sikorski appointed Colonel Rowecki his deputy, with the right to take urgent decisions without seeking the consent of the Polish Government-in-Exile. Sikorski urged Rowecki to work closely with the leaders of Poland's political parties within the Political Consultative Committee.
The ZWZ headquarters formally answered to the Polish Government-in-Exile in London, but in reality its military powers were in the hands of officers who remained in occupied Poland and had a good knowledge of the realities there.
This brief starts where responsible research should: with the source description of “Union of Armed Struggle” as underground army formed in Poland following its invasion by Germany that opened World War II (1939–1942). Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the history & society register because the source frames it as underground army formed in Poland following its invasion by Germany that opened World War II (1939–1942). Its deeper value depends on whether names, dates, institutions and citations support that framing.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Jun 26, 2026. The linked authority identifier is Q1980039. VIAF identifies the subject as 300456302. The Library of Congress control number is n2004026966. None of the 3 selected statements returned an explicit reference. The first chronological checks are 1939, 1942 and 1940.
Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
