Six high-ranking members of Soviet politburo, including Joseph Stalin, sign an order for the execution of 25,700 Polish intelligentsia, including 14,700 Polish POWs, in what will become known as the Katyn massacre.

The Political Bureau of the Central Committee of the Communist Party of the Soviet Union, more commonly known as the Politburo (Russian: Политбюро, abbreviated as Политбюро ЦК КПСС or Politbyuro TsK KPSS), stood as the supreme policy-making authority within the Communist Party of the Soviet Union. This influential body was initially established in October 1917 during the tumultuous revolutionary period, and later refounded in March 1919 at the 8th Congress of the Bolshevik Party, marking its foundational role in the Soviet state. For a significant stretch, from 1952 to 1966, it was officially designated as the Presidium. The Politburo, deeply entwined with the fate of the Soviet Union, ceased to exist in 1991, coinciding with the dissolution of the Soviet state itself.

The Katyn Massacre: A Shadow Over Soviet History

Among the darkest chapters in the history of the Soviet Union is the Katyn Massacre, a series of mass executions that claimed the lives of approximately 22,000 Polish military officers and intelligentsia who had been taken as prisoners of war. This horrific act was orchestrated and carried out by the NKVD (People's Commissariat for Internal Affairs), the Soviet secret police, primarily during April and May of 1940. While the killings occurred in several locations, including the Kalinin and Kharkiv prisons, the massacre takes its name from the Katyn Forest, near Smolensk, where German forces first unearthed some of the mass graves in April 1943.

The chilling decision to liquidate the Polish officer corps originated from a proposal by NKVD chief Lavrentiy Beria to Joseph Stalin, a plan subsequently approved by the Soviet Politburo, with Stalin himself at its head. The victims represented a vital cross-section of Polish society: around 8,000 were officers imprisoned following the 1939 Soviet invasion of Poland, another 6,000 were police officers, and the remaining 8,000 comprised Polish intelligentsia whom the Soviets ominously labeled as "intelligence agents and gendarmes, spies and saboteurs, former landowners, factory owners and officials." The officer class of the Polish Army was, notably, a reflection of the multi-ethnic Polish state, and those murdered included not only ethnic Poles but also Ukrainians, Belarusians, and Jews, among them the revered Chief Rabbi of the Polish Army, Baruch Steinberg.

Upon the German announcement of the discovery of the mass graves in 1943, Stalin reacted by severing diplomatic relations with the London-based Polish government-in-exile, which had courageously requested an investigation by the International Committee of the Red Cross. After the Vistula-Oder offensive brought the mass graves back under Soviet control, the Soviet Union initiated a decades-long campaign of disinformation, falsely blaming the Nazis for the atrocity. This systemic denial, referred to as the "Katyn lie" – a term coined to draw parallels with the "Auschwitz lie" due to its deliberate historical revisionism – persisted until 1990. In a significant turning point, the Soviet Union finally, and officially, acknowledged and condemned the killings perpetrated by the NKVD, as well as the subsequent government cover-up.

Further investigations, conducted by the offices of the prosecutors general of the Soviet Union (1990-1991) and later the Russian Federation (1991-2004), unequivocally confirmed Soviet responsibility for the massacres. However, these investigations controversially declined to classify the actions as a war crime or an act of mass murder, ultimately closing the case on the grounds that the perpetrators were deceased. Furthermore, the Russian government opted not to classify the dead as victims of the Great Purge, thereby deeming formal posthumous rehabilitation inapplicable. It was not until November 2010 that the Russian State Duma approved a declaration explicitly blaming Stalin and other Soviet officials for ordering the massacre, a belated but crucial step towards historical transparency.
