Birkenau had its first documentary mention in 795 in the Lorsch Codex as a cell of the Lorsch Abbey. As one of the Abbey’s holdings, it passed into the ownership of the Archbishopric of Mainz in 1232. The centres of Hornbach and Balzenbach, on the other hand, belonged to the Electorate of the Palatinate, meaning that after the Reformation, they belonged to different denominations. In 1532 the town hall was built, and in 1771 the palace, Schloss Birkenau, of the Lords of Wambolt von Umstadt. By 1964, the population had grown to more than 5,000. In 1967 the community was recognized as a recreational resort (Erholungsort) and in 1979 as an open-air resort (Luftkurort). Owing to the only slight tourism, however, it has not reapplied for this designation. In 1995, Birkenau celebrated its 1,200-year jubilee.

^ Historian H.P. Willmott writes that, "Many examples of the experiences and losses suffered by German formations moving up to the front are well known. Panzer Lehr, for instance, on 7 June alone lost 84 half-tracks, prime movers and self propelled guns, 40 fuel bowsers, 90 soft-skinned vehicles and five tanks as it made its way from Le Mans to Caen.[74]
Soviet civilian populations in the occupied areas were heavily persecuted.[438] Villages throughout the Soviet Union were destroyed by German troops.[439] Germans rounded up civilians for forced labor in Germany and caused famine by taking foodstuffs.[440] In Belarus, Germany imposed a regime that deported some 380,000 people for slave labor and killed hundreds of thousands of civilians. Over 600 villages had their entire populations killed, and at least 5,295 Belarusian settlements were destroyed by the Germans. According to Timothy Snyder, of "the nine million people who were in the territory of Soviet Belarus in 1941, some 1.6 million were killed by the Germans in actions away from battlefields, including about 700,000 prisoners of war, 500,000 Jews, and 320,000 people counted as partisans (the vast majority of whom were unarmed civilians)".[441] The United States Holocaust Memorial Museum has estimated that 3.3 million of 5.7 million Soviet POWs died in German custody.[442] The death rates decreased as the POWs were needed to help the German war effort; by 1943, half a million had been deployed as slave labor.[409]
By July 1944, Germany was losing the war; the SS began closing down the easternmost concentration camps and deporting the remaining prisoners westward. Many were killed in Auschwitz and the Gross-Rosen concentration camp. Schindler convinced SS-Hauptsturmführer Amon Göth, commandant of the nearby Kraków-Płaszów concentration camp, to allow him to move his factory to Brněnec in the Protectorate of Bohemia and Moravia, thus sparing his workers from almost certain death in the gas chambers. Using names provided by Jewish Ghetto Police officer Marcel Goldberg, Göth's secretary Mietek Pemper compiled and typed the list of 1,200 Jews who travelled to Brünnlitz in October 1944. Schindler continued to bribe SS officials to prevent the execution of his workers until the end of World War II in Europe in May 1945, by which time he had spent his entire fortune on bribes and black market purchases of supplies for his workers.
