What happened July 1870 AD

France mobilized and declared war on 19 July. The German states saw France as the aggressor, and—swept up by nationalism and patriotic zeal—they rallied to Prussia's side and provided troops.

Franco-Prussian War or Franco-German War, often referred to in France as the War of 1870, was a conflict between the Second French Empire and the North German Confederation led by the Kingdom of Prussia. Lasting from 19 July 1870 to 28 January 1871, the conflict was caused primarily by France's determination to restore its dominant position in continental Europe, which it had lost following Prussia's crushing victory over Austria in 1866.

Despite having a strong market share, the Franco-Prussian war of 1870 destroyed the velocipede market in France.
