What Do You Already Know About The Holocaust? What About The German, Jewish, and Polish People?

I know about the Germans murdering the jews. I learned about the Auschwitz Concentration camp where german soldiers beat, killed, and worked the jews to death. The germans disarmed the jews from having any chance of fighting back. Some jews were forced to flee German control. Some hid in their houses. Polish people were murdered in the Auschwitz concentration camps, too. They were murdered for their nationality. The whole holocaust started over Adolf Hitler’s religious and systematic beliefs. He wanted to get rid of the jews and wipe them out from the entire planet. Even in the Auschwitz camp, I heard about scientists performing tests on people. They even put older people and children inside gas chambers, gassing them. They burned bodies for their own selfishness.
