The Polish Underground State (Polish: Polskie Państwo Podziemne, also known as the Polish Secret State)[a] was a single political and military entity formed by the union of resistance organizations in occupied Poland. They were loyal to the Polish government-in-exile in London. The armed wing of the Polish Underground State is called the Home Army.

The size of the Home Army throughout its existence is outlined as follows.
| Year | Size |
|---|---|
| 1942 | 100,000 |
| 1943 | 200,000 |
| 1944 | 400,000 |

The Home Army Headquarters was divided into two bureaus, five sections and several other specialized units:
The Home Army's commander took orders from the Polish Commander-in-Chief (General Inspector of the Armed Forces) of the Polish government-in-exile and the Government Delegation for Poland.

After Nazi Germany was defeated, the Soviet Union set up a puppet state in Poland, subjecting Poland to communist totalitarianism until 1989, while Soviet troops did not leave Poland until 1993. The puppet state's founding came with the arrest of 25,000 Polish Home Army soldiers, who were deported to Gulag camps in Russian mainland. As many as 100,000 Polish women were also raped by Soviet soldiers.
Some anti-communist Poles rose up in arms against the Soviet occupiers right after the war. However, the armed resistance failed due to the lack of external support. Tens of thousands of them were deported to Gulag camps as well, with a few to no confirmed survivors. Among them consisted of 6,000 Poles being jailed in Borowicze (now Borovichi, Russia) and 6,300 in Stalinogorsk (now Novomoskovsk, Russia). The exact number is unknown due to the lack of access to all of the relevant Soviet documents.
When Jews insisted on highlighting antisemitism [...] they were accused of reactionary particularism [. ...] much of the left resisted attempts to present the Nazi genocide as a Jewish cataclysm [. ...] It did not see the oppression of Soviet Jewry, or the desperate flight of Ethiopian Jews, as issues [. ...] Stalinist purges [...] Jews [...] as cosmopolitans and Zionist agents. In 1968-69 the Polish Communist Party conducted an anti-Zionist attack on [...] its Jewish population of 35,000, resulting in the forced emigration of approximately 25,000 of them.
