Only with the achievements of the Revolution of 1848 were Jews permitted free settlement and thus also the foundation of their communities. Jewish immigrants moved into Lower Austria particularly from Bohemia, Moravia and Western Hungary (today’s Burgenland), they spoke German and were traditional in religious terms but not orthodox. 

1863 saw the official foundation of the Jewish Religious Community (IKG) St. Pölten; the catchment area included Traismauer in the north, St. Aegyd am Neuwald in the south, Krummnußbaum in the west and Hadersdorf-Weidlingau in the east. 

As of November 2020, we know the names of 1,045 people in the vicinity of the IKG St. Pölten who were persecuted between 1938 and 1945 on the basis of the "Nuremberg Race Laws". In March 1938, 577 of these people were living in the area of the IKG St. Pölten. 321 of them were murdered in the Shoah, 214 were able to escape and the fate of 42 others is unknown. For 168 other people, we are currently unable to determine beyond doubt whether they were present in March 1938. Of these, 50 people were murdered and 58 were able to escape. The fate of the remaining 60 people is uncertain. A further 301 people, mainly children of St. Pölten Jews, no longer lived in St. Pölten during the Anschluss, but appear in the memorial book due to family ties. 135 of them were victims of persecution, 134 were able to escape. There is no further information on 32 people.
