Poland and Ukraine held joint commemorations this July to mark the 81st anniversary of the Volhynia massacre, a series of mass killings committed by the Ukrainian Insurgent Army (UPA) during the Second World War. The events, which peaked on what is historically referred to as “Bloody Sunday” in July 1943, remain a deeply sensitive point of contention in the diplomatic relationship between Warsaw and Kyiv, even as the two nations maintain a close strategic alliance following the 2022 Russian full-scale invasion of Ukraine.
According to historical records maintained by the Institute of National Remembrance (IPN) in Poland, the massacres involved the systematic targeting of ethnic Poles in the regions of Volhynia and Eastern Galicia. Historians estimate that between 50,000 and 100,000 Polish civilians were killed by UPA forces between 1943 and 1945. The IPN, which serves as the primary state body for investigating Nazi and Communist-era crimes, classifies these actions as genocide.
Historical Context and the Legacy of 1943
The violence erupted during the German occupation of territories that were part of the Second Polish Republic before 1939. The UPA, the military wing of the Organization of Ukrainian Nationalists (OUN-B), sought to create an independent Ukrainian state through the removal of non-Ukrainian populations. On July 11, 1943, coordinated attacks were carried out against approximately 100 Polish villages simultaneously, a day now commemorated annually in Poland as the National Day of Remembrance for the Victims of the Genocide of Citizens of the Polish Republic.
The issue of how to characterize these events remains a point of divergence. While Polish officials and historians emphasize the systematic and organized nature of the killings, Ukrainian perspectives often frame the conflict as a reciprocal tragedy involving ethnic cleansing on both sides, albeit with a significantly lower number of Ukrainian casualties. The national news agency of Ukraine, Ukrinform, has documented efforts by both governments to facilitate dialogue and exhumation processes, though progress on the formal search and burial of remains has been slow due to ongoing geopolitical tensions and the current war.
Diplomatic Efforts and Current Relations
In recent years, both nations have signaled an intent to move toward reconciliation despite the weight of history. Polish President Andrzej Duda and Ukrainian President Volodymyr Zelenskyy have participated in joint memorial services, emphasizing the need for historical truth as a foundation for future cooperation. In July 2023, the two leaders attended a ceremony in Lutsk, Ukraine, to honor the victims together, a gesture that signaled a shift toward addressing the tragedy in a spirit of transparency.
The Polish Ministry of Foreign Affairs continues to advocate for the right to exhume and commemorate victims on Ukrainian soil, citing this as a necessary step for historical reconciliation. For Ukraine, the challenge lies in balancing the integration of OUN/UPA figures into their national liberation narrative with the necessity of maintaining a vital security partnership with Poland, which has served as a primary transit hub for Western military and humanitarian aid since February 2022.
Moving Toward Reconciliation
The path forward involves complex negotiations regarding the legal status of exhumations. Polish authorities have repeatedly requested permission for the Institute of National Remembrance to conduct search operations in sites across Volhynia. Ukrainian officials have indicated that these requests are being processed, though the ongoing conflict complicates access to certain regions and the allocation of resources for such historical investigations.

As both countries look toward the future, the commemorations serve as a reminder that political alliances are often tested by the unresolved traumas of the past. The next significant checkpoint for this issue will likely involve the Polish-Ukrainian intergovernmental consultations, where historical memory and the management of burial sites are expected to remain on the agenda alongside security and economic cooperation. Readers interested in the official progress of these exhumation requests and ongoing commemorative events can monitor updates through the official portals of the Polish Ministry of Foreign Affairs and the Ukrainian Institute of National Memory.
