The increasingly totalitarian regime that Hitler imposed on Germany allowed him to control the actions of the military. On November 7, 1938, a young Polish Jew named Herschel Grynszpan attacked and shot German diplomat Ernst vom Rath in the German embassy in Paris. Grynszpan's family, together with more than 12,000 Polish-born Jews, had been expelled by the Nazi government from Germany to Poland in the so-called ""Polenaktion"" on October 28, 1938. Joseph Goebbels ordered retaliation. On the night of November 9, the SS and SA conducted "the Night of Broken Glass" (""Kristallnacht""), in which at least 91 Jews were killed and a further 30,000 arrested and incarcerated in Nazi concentration camps. After the start of the war, and the conquest of numerous European countries, the Jewish population was put into ghettos, from which they were shipped to death camps where they were killed.
