Entire Jewish population of Trier, Germany slaughtered.
The Cathedral of Trier, the seat of the Roman Catholic Bishop of Trier, is the oldest (340s CE) cathedral in Germany.
Trier is located on the Moselle River, in what was then the ancient northern capital of the Holy Roman Empire. For a span, Trier was known as the seat of several sequential, powerful Catholic bishops. The town then ultimately passed through French hands (1794), and then into Prussian hands (1815). The particular Prussian area later became part of Germany (1871).
