A new diplomatic scandal has erupted between Poland and Ukraine, two countries that since Russia’s full-scale invasion of Ukraine have been among the closest strategic partners in Central and Eastern Europe. The dispute concerns history, memory and one of Poland’s most prestigious state symbols: the Order of the White Eagle.

The immediate cause of the controversy was a decision by Ukrainian President Volodymyr Zelensky to grant the honorary name “Heroes of the UPA” to a Ukrainian special forces unit. For many Ukrainians, the Ukrainian Insurgent Army — known by its Ukrainian acronym UPA — is associated with the struggle for national independence, especially resistance to Soviet domination. For many Poles, however, the same organization is inseparably linked with one of the most traumatic chapters of twentieth-century Polish history: the massacres of Polish civilians in Volhynia and Eastern Galicia during the Second World War.

In Poland, the UPA is not remembered primarily as an anti-Soviet resistance movement, but as an organization responsible for the mass killing of Polish civilians in 1943–1945. Polish historians, public institutions and much of Polish public opinion describe these events as genocide or genocidal ethnic cleansing. Tens of thousands of Poles — often entire villages, including women, children and the elderly — were murdered in territories that before the war belonged to the Second Polish Republic and are today largely within Ukraine.

This is why Zelensky’s decision caused outrage in Warsaw. Polish President Karol Nawrocki announced that he would ask the Chapter of the Order of the White Eagle to discuss stripping Zelensky of Poland’s highest decoration. The Ukrainian president received the order in 2023 from then-President Andrzej Duda, at a moment when Polish-Ukrainian solidarity seemed especially strong. The decoration was meant to honor Zelensky’s leadership in resisting Russian aggression and his role in defending European security.

The symbolic weight of the possible revocation is enormous. The Order of the White Eagle is Poland’s oldest and highest state distinction, awarded to people considered to have rendered exceptional service to the Polish state. Taking it away from the president of a neighboring country — especially one fighting a defensive war against Russia — would be an extraordinary diplomatic gesture.

The scandal shows how fragile Polish-Ukrainian reconciliation remains. Since 2022, Poland has been one of Ukraine’s most important supporters. It opened its borders to millions of Ukrainian refugees, became a crucial logistical hub for Western military aid and strongly backed Ukraine’s European aspirations. Yet beneath this strategic alliance lies a painful historical dispute that has never been fully resolved.

For Ukrainians, figures and organizations connected with twentieth-century nationalism are often seen through the prism of anti-imperial struggle. In the Ukrainian national narrative, the UPA is frequently presented as part of the long fight against Moscow and Soviet oppression. For Poles, however, any official glorification of the UPA is perceived not as a neutral historical reference, but as an insult to the victims of the Volhynia massacres and their descendants.

This difference in memory is not a minor academic disagreement. It touches the deepest layers of identity in both countries. Ukraine, fighting for survival against Russia, seeks historical symbols of resistance. Poland, also deeply marked by occupation, war and mass murder, expects its ally to recognize the suffering of Polish civilians and avoid honoring perpetrators of crimes against them.

The political context makes the dispute even more sensitive. Moscow has long tried to exploit historical tensions between Poland and Ukraine. Russian propaganda frequently presents Ukrainian nationalism as inherently extremist and tries to weaken Polish support for Kyiv by invoking the memory of Volhynia. For that reason, even Polish politicians who strongly criticize Zelensky’s decision warn that an uncontrolled escalation of the dispute could benefit Russia.

The controversy therefore creates a difficult dilemma for Warsaw. On the one hand, ignoring the official glorification of the UPA would be politically and morally unacceptable to many Poles. On the other, a dramatic diplomatic rupture with Ukraine would weaken the regional front against Russian aggression. Polish leaders must balance historical justice with strategic responsibility.

For Kyiv, the lesson is equally serious. Ukraine’s struggle against Russia has earned it enormous sympathy in Poland, but that sympathy does not erase historical memory. If Ukraine wants to deepen its integration with Europe, including with Poland as one of its key advocates, it will have to deal more carefully with the darker parts of its twentieth-century nationalist tradition. Honoring military courage against Russia cannot come at the price of denying or minimizing crimes against civilians.

The dispute over the Order of the White Eagle is therefore more than a quarrel over a medal. It is a test of whether Poland and Ukraine can build an alliance mature enough to face both Russian aggression and painful historical truth. Real reconciliation cannot be based on silence. But it also cannot become a weapon that destroys present-day solidarity.

For foreign observers, the scandal is a reminder that Central and Eastern European politics cannot be understood through geopolitics alone. Memory, symbols and unresolved historical wounds continue to shape alliances. Poland and Ukraine may share a common strategic enemy today, but their partnership will remain vulnerable unless they find a language that honors both Ukrainian independence and Polish victims.
