Viktors Arājs (13 January 1910 – 13 January 1988) was a Latvian collaborator and Nazi SS officer, who took part in the Holocaust during the German occupation of Latvia and Belarus (then called White Russia or White Ruthenia) as the leader of the Arājs Kommando. The Arajs Kommando murdered about half of Latvia's Jews.
Viktors Bernhard Arājs was born on 13 January 1910 in the town of Baldone, then part of the tsarist empire. His father was a Latvian blacksmith and his mother came from a wealthy family of Baltic Germans. Arājs attended Jelgava Gymnasium, which he left in 1930 for mandatory national defense service in the Latvian Army. In 1932, Arājs studied law at the University of Latvia in Riga, but completed his degree only in 1941 after the Soviet occupation. He was a member of the elite student fraternity "Lettonia", which may have helped him get a job with the Latvian police after he left the university. Arājs remained with the Latvian police until he left the service in 1938. During the Ulmanis dictatorship in Latvia 1934–1940, Arājs was a "low ranking provincial police officer" who, as a loyal administrator, dutifully "distanced himself officially from the Pērkonkrusts", the Fascist party in Latvia.
The war between Germany and the Soviet Union began on 22 June 1941. Shortly afterwards, the Red Army abandoned Riga to the advancing Wehrmacht. Arājs then took over an abandoned police precinct house at 19 Valdemāra Street. Arājs's future commanders, Franz Stahlecker and Robert Stieglitz, had with them a Latvian translator, Hans Dressler, whom Arājs had known in high school and in the Latvian army. Because of this friendship, Arājs was introduced to Stahlecker, got on their best side, and gained their trust. Arājs recruited the core of his troops from his student fraternity and Pērkoņkrusts.
