the main contribution of the austrians in the time period from 1500 to 1800 was the halting of the advances of the Ottoman Turks
The so-called "Ottomans" came into Western consciousness when they relocated from their native Central Asia to the Seljuk Sultanate of Rum in Anatolia in the 13th century. In Western Anatolia, the Ottoman Turks established a beylik with Söüt as its capital under Ertugrul's rule. The chief of the nomadic Kay tribe, Ertugrul, established the first principality during the final years of the Seljuk empire. His son Osman expanded the principality, and in recognition of him, Europeans gave the people and the political system the name "Ottomans" ("Ottoman" being a corruption of "Osman"). Osman's son Orhan turned the expanding area into an empire in 1362 with the conquest of Nicaea (modern-day Znik) and the traversal of the Dardanelles.

The Nazi Germany built concentration camps all along the German-occupied territories in order to make war prisoners work while living in extreme poor conditions. Thousands of ordinary people were imprisoned and enslaved as a condition to respond to the German war effort. Prisoners who suffered from starvation, diseases and executions had been put into these camps because of the racist policies.
During the Holocaust the Germans turned Auschwitz into the major concentration death camp because of its extermination facilities. Besides, a great number of Jews lived in Eastern Europe, particularly in Poland. Jews were taken to Auschwitz death camp, killed by annihilating gas in the chambers and then, their bodies were burnt in the crematoria. At this place, the Germans could hide the evidence of these crimes.
