Weimar was important to the Nazis for two reasons : first , it was where the hated Weimar Republic was founded , and second , it had been a centre of German high culture during recent centuries . In 1926 , the NSDAP held its party convention in Weimar . Adolf Hitler visited Weimar more than forty times prior to 1933 . In 1930 , Wilhelm Frick became minister for internal affairs and education in Thuringia , the first NSDAP minister in Germany . In 1932 , the NSDAP came to power in Thuringia under Fritz Sauckel . In 1933 , the first Nazi concentration camps were established around Weimar in Nohra ( the first one in Germany ) and Bad Sulza . Most prisoners at this time were communists and social democrats . After Kristallnacht in 1938 , harassment of Jews became more intense , so that many of them emigrated or were arrested . The Weimar Synagogue was destroyed in 1938
