Pursuit of Nazi collaborators

The pursuit of Nazi collaborators refers to the post-World War II pursuit and apprehension of individuals who were not citizens of the Third Reich at the outbreak of World War II and collaborated with the Nazi regime during the war. Hence, this article does not cover former members of the NSDAP and their fate after the war.

There were a number of motives for the apprehension of suspected collaborators. The main motives were: revenge for those murdered, especially those murdered on ethnic grounds in the Holocaust (principally amongst Jews, Poles, and Russians); a desire after the bitter war to see those responsible face justice, and be categorised as criminals by a court of law (See Nuremberg Trials); a means of ensuring that criminal acts done were brought to light and placed on the official record, with evidence, so that they could never be disproven (some of the acts being so unthinkable that denial was plausible); widespread sense that genocide of whole communities and cultures on such a scale was intolerable and must not be left unprosecuted even despite the inadequacy of existing laws; and fear that a "Nazi underground" of some kind existed, such as the mythical ODESSA, which could allow the enemy to somehow regroup for their proclaimed Fourth Reich.

The pursuit took many forms, both individual and organised. Several organisations and individuals (famous Nazi hunters) pursued ex-Nazis or Nazi collaborators who allegedly engaged in war crimes or crimes against humanity. The pursuit took varied forms such as individuals who reported they saw someone who they recognised, who had now assumed a false identity intent on slipping back into civilian life undetected. Specific individuals were named and sought by groups or governments for their crimes during the war.
