Diepoldsau

History

Diepoldsau is first mentioned in 891 as Thiotpoldesouua. Schmitter is first mentioned in 1385. This was in keeping with Switzerland's policy that religious communities were financially responsible for refugees of their denomination, which put tremendous pressure on the comparatively small Jewish communities. The Swiss federal government did not contribute. The refugees were not permitted to seek work and were subject to frequent police controls and restrictive measures.
