Leading Nazis had gathered here to celebrate the 15th anniversary of the Munich Beer Hall Putsch a sacred date for the Nazi party.
On the evening of 9th November, they learnt that a German diplomat in Paris had been shot by a German-Polish Jew.
Joseph Goebbels, the propaganda minister, a vicious anti-Semite himself, suggested to Hitler that Nazi Stormtroopers be let loose against the Jews of Germany.
This was how Hitler's charismatic leadership could work-he had a vision, he hated the Jews and wanted to get rid of them, but others suggested the ways in which this could be implemented.
Hitler agreed with Goebbels' idea and so, Nazi Stormtroopers ran wild on the night of 9th November, attacking Jews and their property.
Around 25,000 Jews were imprisoned in concentration camps and more than 100 were murdered.
Shortly afterwards, the SS newspaper warned of terrible consequences if a Jew assassinated another leading German.
"There will be no more Jews in Germany.
"We hope we make ourselves clear!"
They also threatened...
"Because no power on Earth can stop us, we will bring the Jewish question to its total solution.
"The programme is clear-total expulsion, complete separation."
