Sobibór extermination camp: Sobibór (or Sobibor , or , ] ) was a Nazi German extermination camp built and operated by the SS near the railway station of Sobibór during World War II, within the semi-colonial territory of General Government of the occupied Second Polish Republic.  The camp was part of the secretive Operation Reinhard, which marked the deadliest phase of the Holocaust in German-occupied Poland.  The camp was situated near the rural county's major town of Włodawa (called "Wolzek" by the Germans), 85 km south of the provincial capital, Brest-on-the-Bug (Brześć nad Bugiem in Polish).  Its official German name was "SS-Sonderkommando Sobibór".  Jews from Poland, France, Germany, the Netherlands, Czechoslovakia and the Soviet Union (including Jewish-Soviet POWs), were transported to Sobibór by rail.  Most were suffocated in gas chambers fed by the exhaust of a large petrol engine.  Up to 200,000 people were murdered at Sobibór and possibly more.  At the postwar trial against the former "SS" personnel of Sobibór, held in Hagen two decades into the Cold War, Professor Wolfgang Scheffler estimated the number of murdered Jews totalled a minimum of 250,000.  This would make it the fourth worst extermination camp, after Bełżec, Treblinka, and Auschwitz.

History of the Jews during World War II: The history of the Jews during World War II is almost synonymous with the Jewish persecution and murder of unprecedented scale in modern times in political Europe inclusive of European North Africa (pro-Nazi Vichy-North Africa and Italian Libya).  The massive scale of the Holocaust which happened during World War II heavily affected the Jewish nation and world public opinion, which only understood the dimensions of the Final Solution after the war.  The genocide known as HaShoah in Hebrew, aimed at the elimination of the Jewish people on the European continent.  It was a broadly organized operation led by Nazi Germany, in which approximately six million Jews were murdered methodically and with horrifying cruelty.  During the Holocaust in occupied Poland, more than one million Jews were murdered in gas chambers of the Auschwitz concentration camp alone.  The murder of the Jews of Europe affected Jewish communities in Albania, Austria, Belarus, Belgium, Bosnia & Herzegovina, Channel Islands, Croatia, Czech Republic, Estonia, France, Germany, Greece, Hungary, Italy, Latvia, Libya, Lithuania, Luxembourg, Macedonia, Moldova, The Netherlands, Norway, Poland, Romania, Russia, Serbia, Slovakia, and Ukraine.
