Krefeld, also known as Crefeld until 1929, is a city in North Rhine-Westphalia, Germany. It is located northwest of Düsseldorf, its centre lying just a few kilometres to the west of the River Rhine; the borough of Uerdingen is situated directly on the Rhine. Krefeld is also called the "Velvet and Silk City".
A reform synagogue was built in 1876, arousing opposition from the Orthodox community. A Jewish school existed in the town, with more than 200 students around 1900. In 1938 during Kristallnacht, the two synagogues were attacked and burnt.
