June–July 1941

June–July 1941: anti-Jewish pogroms in western Ukraine and OUN-B role — Bandera's personal responsibility not established

No legal proceedings

Activists and structures linked to the OUN-B participated in incitement and anti-Jewish violence in western Ukraine at the time of the German invasion. Bandera's movement therefore forms an important organisational context for the 1941 pogroms.
