Did anyone oppose Hitler?

Yes, people protested against him at various points in time. A few hid the opponents of the regime and the Jews from the authorities. Groups like the ‘White Rose’ by The Scholl siblings distributed handouts and asked the people to revolt against the Nazi regime. Businessmen like Oscar Schindler employed the CC detainees in their factories in order to protect them from the death camps. High military officials attempted to assassinate Hitler but without success. Workers in the arms factories intentionally produced defective weapons, and there were revolts in ghettos and concentration camps. In addition, in the occupied territories, the armed groups fought underground. However, most of the people remained inactive out of fear because whosoever was betrayed or discovered had to pay the price with his life.
