This article will trace the origins of the OUN and explain its history up to the eve of [the Axis] invasion of the Soviet Union. By then the OUN, working closely with both [Wehrmacht] intelligence (the Abwehr) and the SS, had begun to plan their [ethnocidal] takeover of Ukraine. From [Fascist] occupied Poland the OUN/B controlled over 20,000 underground activists ready to take up arms to exterminate Jews, Poles, and Russians and organize a warm welcome for the [Axis] in Soviet Ukraine.

Part two will cover the horrific war crimes the OUN carried out during the war. In part one I will be relying mostly on the definitive, Stepan Bandera The Life and Afterlife of a Ukrainian Nationalist: Fascism, Genocide, and Cult”, by Grzegorz Rossolinski-Liebe, which I recommend to anyone looking to do an in-depth study of the history of the OUN.
