Hamelin was part of the Kingdom of Westphalia between 1807 and 1813. For the people of Hamelin, it was a time of war, with troops constantly marching through, soldiers stationed in the city, conscription and, finally, the battle against Napoleon himself. But the freedoms of the French era were not quickly forgotten. Equality of all people before the law had become a hot topic in Hamelin too.
People of different upbringings could now meet and converse at reading clubs and associations. But the authorities did not approved. The revolution in Paris raised tempers in Hamelin. The craftsmen's union played a major role in organising demonstrations.
However, the hard-fought Citizens' Commission set up by citizens and workers lasted just a few months. There was no revolution.
Agriculture and crafts were developing fast. Hamelin's crafts workshops were converted into factories using new methods, new tools and new machines. The economy was boosted by the invention of steam shops and the railway. Newspapers, telegraphy and telephones speeded up communications. But some fell by the wayside along the path of progress.
The defeat of the Kingdom of Hanover at Langensalza hit the supporters of the House of Guelf in Hamelin hard. The unification of the kingdom posed them with a dilemma, as the leaders of the unified country were Prussian!
Tourism prospered when a railway connection was built and steam ship trips along the Upper Weser became a popular attraction. But the real breakthrough came with the first Pied Piper Festival in 1884, when the town decided to put on a big event. Many of the people of Hamelin were surprised at how successful it was. The mountains of Weser became a destination for holidaymakers seeking calm and relaxation.
