On 13 March 1933, elections were held in Frankfurt, and Adolf Hitler's Nazi Party won. Acts of Antisemitism began almost immediately. The Franks were afraid of what might happen to them if they stayed in Germany. Therefore, later that year, Edith and the children went to Aachen. They stayed there with Edith's mother, Rosa Holländer. Otto remained in Frankfurt, but after getting an offer to start a company in Amsterdam, he moved there to begin the business and to find a place to live with his family. The Franks were included in the 300,000 Jews who ran away from Germany between 1933 and 1939.
