 Latvia became a part of Nazi Germany's Reichskommissariat Ostland as the Province General of Latvia ("Generalbezirk Lettland").Anyone who was disobedient to the German occupation regime or had co-operated with the Soviet regime was killed or sent to concentration camps.Immediately after the installation of German authority (the beginning of July 1941) a process of eliminating the Jewish and Gypsy population began, with many killings taking place in Rumbula.
