Generalbezirk Litauen (Lithuanian: Lietuvos generalinė sritis, lit. 'General District Lithuania') was an administrative subdivision of the Reichskommissariat Ostland of Nazi Germany that covered Lithuania from 1941 to 1944. It served as the Nazi civilian administration for the German occupation of Lithuania during World War II.
Adrian von Renteln was the only Generalkommissar of Generalbezirk Litauen during its existence.
The Fareynikte Partizaner Organizatsye (Yiddish: פֿאַראײניקטע פּאַרטיזאַנער אָרגאַניזאַציע; "United Partisan Organization"; referred to as FPO by its Yiddish initials) was a Jewish resistance organization based in the Vilna Ghetto in German-occupied Lithuania and founded on January 21, 1942. The clandestine organisation was established by Communists as well as left- and right-wing Zionists. Their leaders were the Communist Yitzhak Wittenberg, Socialist Abba Kovner, and revisionist Betar member Josef Glazman.
The Lithuanian Auxiliary Police was a Schutzmannschaft formation formed during the German occupation of Lithuania between 1941 and 1944, with the first battalions originating from the most reliable freedom fighters, disbanded following the 1941 anti-Soviet Lithuanian June Uprising in 1941. Lithuanian activists hoped that these units would be the basis of a reestablished Lithuanian Army commanded by the Lithuanian Provisional Government. Instead, they were put under the orders of the SS- und Polizeiführer in Lithuania.
Lithuanian auxiliary policemen were divided into four types. The first three were: regular law enforcement policemen, firefighting policemen, and auxiliary units grouped into platoons that assisted the local police when needed. The last were Lithuanian Schutzmannschaft battalions, closed formations organized into battalions, companies, platoons and groups.
