April 19, 1943 - On the eve of Passover, the Warsaw Ghetto Uprising began when Nazi forces attempted to clear out the Jewish ghetto in Warsaw, Poland, to send them to concentration camps. The Germans were met by unexpected gunfire from Jewish resistance fighters. The destruction of the ghetto had been ordered in February by SS Chief Heinrich Himmler:

“An overall plan for the razing of the ghetto is to be submitted to me. In any case we must achieve the disappearance from sight of the living-space for 500,000 sub-humans (Untermenschen) that has existed up to now, but could never be suitable for Germans, and reduce the size of this city of millions—Warsaw—which has always been a center of corruption and revolt.”
