The Holocaust affected millions of people in Germany, Europe, and throughout the world. Both sides of this huge event were greatly affected by the things that happened during the Holocaust. The Nazi party's rise to power, led by Adolf Hitler, took over Germany for the course of 12 years, which will be remembered as some of the most tragic years in the 20th century. The genocide of Jews and other 'inferiors' resulted in more than 11 million dead by the time the Allied forces invaded Germany, and that isn't counting the thousands of Nazi members and their families that committed suicide or murder-suicide after the Allied invasion.
When Hitler came to power in 1933, he had already created a large following. Because of this, it was easy for him to make the transition and start putting his discrimination laws into place. First, it was the boycott of Jewish business. In no time, it had spiraled into nothing more than rounding up the 'inferiors' and sending them off to camps where they would be put into forced labor, used for medical experimentation, kept in harsh living quarters, and eventually killed. Some, if they went directly to extermination camps, were killed upon arrival. Although the camps didn't become popular until around 1940, thousands of Jews were killed in them on a regular basis.
There are also the Nazis to think about in this event. The Nazi people believed that there was a need for a Master Race and took the loss of World War I very personally. They were white supremacists, believing that the Aryan race was superior to the rest and that anyone else was expendable. This belief system was built on the ideologies of fascism and anti-Semitism, and eventually fueled by so much propaganda that even the general public started to believe that what their leaders were doing was okay.
The Nazis had families, including children. A lot of people don't discuss this part of the Holocaust, however. There were countless children of some of the most prominent Nazi leaders, and although Hitler himself officially never had children, he was the godfather to some and was well-liked among the spouses and children of his men. These children have grown, some have died, and others have denounced their family name. There are still some who claim their ancestors could have never done such a thing, but there are also those who know who their ancestors are and who feel an obligation or guilt toward the victims of the Holocaust simply because of their genetics.
