Persecution of Jews increased during World War II as the Nazis invaded more countries; which contained thousands of Jews. The increase in the number of Jews caused the problem to increase significantly. The way the Nazis treated the Jews gradually changed over the years. First we started by isolating them from society, then with exportation outside Europe, then with ghettoisation; which failed due to the huge number of people. They later introduced methods such as Einsatzgruppen, concentration and labor camps and gas chambers. In this essay I will describe each of these methods that contributed to the elimination of the Jews from 1941 onwards. The Einsatzgruppen were formed by Himmler and Heidrich. The Einsatsgruppen were a special action group known as mobile death squads. The special actions this group referred to were mass murders. Their operations marked the initial stages of the planned extermination of the Jews in Europe. They were the heralds of the Holocaust. These squads were sent with the armies to remove the Jews in the conquered countries. One way they proceeded was mass shootings, these shootings took place in secluded and isolated areas. Jews were lined up and shot, sometimes forced to dig their own graves before being shot. To ensure that no one knew about these mass murders, they destroyed all evidence by burning the bodies or burying them. It wasn't long before the Nazis realized that it was less efficient as it took too much time, too many men, wasted too many bullets and seemed to have a detrimental psychological effect on the men. This led them to introduce other methods. The use of noxious gases to kill humans was the next action. The SS discovers... in the middle of the paper... or for long hours. Upon their arrival they had to shower in freezing or hot conditions, they had their hair shaved so they all looked the same. They were not called by their name but by a number that was painfully tattooed on their arm. They were given uniforms that they had to wear during their time in the camps. Their identity has been stripped from them. In these camps they worked producing goods, clothes, jewelry, war products or anything that benefited the Nazis. Just like in the ghettos, Jews had to live in inhumane conditions. There was not enough food and lack of hygiene as a result people died of hunger and disease. They were forced to work for more than 10 hours a day without any breaks. Those who couldn't make it were killed. The surviving Jewish prisoners were the ones who assisted the Nazis in disposing of the corpses and cleaning up.
