Vor wie vielen Jahren gab es erstmals eine jüdische Gemeinde auf dem Gebiet des heutigen Deutschlands?

Explanation

The Jewish community in what is now Germany has a long history that dates back to Roman times. Around 1700 years ago, in 321 AD, Jews were legally recognized in the city of Cologne, marking the beginning of a continuous Jewish presence in Germany. This early integration and the subsequent developments are important for understanding the religious and cultural diversity in Germany and its impact on society.
