Polish-Ukrainian solidarity over Russian threat undermined by bitter historical dispute

Kyiv's decision to honour second world war fighters who killed about 100,000 Poles has revived simmering tensions

In the aftermath of Russia's attack on Ukraine in February 2022, Polish-Ukrainian solidarity emerged as one of the most heartwarming subplots of the Kremlin's brutal war. Millions of Poles, remembering their country's own tragic history with Russia, mobilised to help Ukrainian refugees with food, shelter and support as they crossed the border in huge numbers to flee the conflict.

Four years later, that outpouring of generosity and solidarity is a distant memory, as the two countries find themselves locked in a bitter dispute over history that has led to angry rhetoric, mutual mud-slinging and a threat from Poland to block Ukraine's EU accession until it gets its historical house in order.
