In 1919 , after the American-Rusyns agreed with Tomáš Masaryk to incorporate Carpathian Ruthenia into Czechoslovakia , the whole of Carpathian Ruthenia was occupied by Czechoslovak troops . On June 4 , 1920 , Mukachevo officially became part of Czechoslovakia by the Treaty of Trianon . In November 1938 , a part of the territory of the former Kingdom of Hungary was re-annexed by Hungary as part of the First Vienna Award . Without delay the new authorities decreed the expulsion of all the Jews without Hungarian citizenship . As a consequence Polish and Russian Jews , long-term residents of the now Hungarian-controlled Transcarpathian region , and also from Mukachevo , as well as the native Jews who could not prove their citizenship , were deported over the Ukrainian border where their fate was sealed by the hands of a German Einsatzgruppe commando led by Friedrich Jeckeln . On August 27 and 28 1941 they were all murdered by the Germans in Kamianets-Podilskyi 's massacre . Even so , Mukachevo 's population still held an important Jewish component , until in 1944 all the Jews were deported to Auschwitz by the Nazi German Eichmann Commando . They were the last Jewish community in Europe to succumb to the Holocaust
