Napoleon was at the height of his power. He marched into Berlin shortly afterwards. The Prussian king fled to East Prussia. Napoleon could no longer be prevented from reshaping Europe to his liking. Hassenhausen thus unintentionally became a symbolic place in European history.
The museum in the vicarage commemorates the events of 1806: around 15,000 people were fatally wounded on October 14, 1806. Military-political calculations on both sides did not (and unfortunately still do not) care about individual human lives. Among those who fell victim to this battle was the commander-in-chief of the Prussian army: Duke Carl Wilhelm Ferdinand of Brunswick. He was not only an important military leader, but also a great reform-minded politician of his time, and as a person he embodied the tragedy and contradictions of the time. It therefore makes sense to portray the events of that time as the crossroads of an entire era.
