The Volhynia Massacres

Ukrainian nationalist forces kill tens of thousands of Polish civilians in Volhynia and Eastern Galicia, and Polish reprisals follow.

Debated by historians wartraumaidentity

Volhynia, in today’s north-western Ukraine, belonged to Poland between the wars. Its population was mostly Ukrainian, with a substantial Polish minority. Interwar Polish rule and Ukrainian nationalist violence had already poisoned relations. Then came Soviet occupation, Nazi occupation and the Holocaust, in which many of the men who later formed the UPA had served as German auxiliary police.

In 1943 units of the Bandera wing of the Organization of Ukrainian Nationalists (OUN-B) and its Ukrainian Insurgent Army (UPA) began killing Polish villagers across Volhynia. The killing then spread to Eastern Galicia until 1945. The aim was to remove Poles from lands the nationalists claimed for a future Ukrainian state.

The bloodiest day was 11 July 1943, when UPA units attacked about a hundred Polish villages (99, according to Poland’s Institute of National Remembrance) in a coordinated wave.

The numbers are disputed. Polish historians and the Polish state put the number of Polish civilians killed in Volhynia, Eastern Galicia and neighbouring areas at about 100,000; the historian Grzegorz Rossoliński-Liebe gives 70,000–100,000. For Volhynia alone, estimates run from about 35,000 to 60,000, and some scholars, such as Ivan Katchanovski, consider the lower end more reliable. Polish reprisals killed Ukrainians too: Poland’s Institute of National Remembrance puts the toll at about 10,000, and Rossoliński-Liebe at 10,000–20,000, fighters and civilians.

The conflict ended with population exchanges and, in 1947, Poland’s “Operation Vistula”, which forcibly scattered the remaining Ukrainians of south-eastern Poland across the country’s west and north.

Two memories

In Poland, Volhynia is remembered as genocide. In 2016 the Sejm (parliament) formally declared it so and made 11 July a national day of remembrance. Polish historians broadly agree that it was a planned campaign with features of genocide.

In Ukraine the picture is blurrier. The Ukrainian parliament called the Polish resolution an inaccurate political and legal assessment and said that all victims in both countries should be commemorated equally. Surveys suggest many Ukrainians know the massacres only vaguely and have no clear view of the UPA’s responsibility. A 2015 Ukrainian law honouring the UPA among fighters for independence deepened Polish anger.

Presidents and churches of both countries have issued statements of reconciliation, but the issue keeps resurfacing.

How it's seen
The Polish view

A planned extermination of Polish civilians by the OUN-B and UPA, with features of genocide. Poland's parliament declared it a genocide in 2016 and made 11 July a national day of remembrance.

The Ukrainian official and popular view

A tragic chapter of a Polish–Ukrainian conflict with victims on both sides. Ukraine's parliament rejected Poland's genocide resolution as an inaccurate assessment and said all victims in both countries should be commemorated equally; many Ukrainians have no clear view of the UPA's responsibility.

Why it matters today

Ukraine

Volhynia is the most painful issue between Ukrainians and Poles, close allies today. In Poland it is a national day of remembrance. Many Ukrainians know it only vaguely, and official Ukraine has framed it as a tragedy with victims on both sides. It still flares up in politics between the two countries.
