Amiens is a city in northern France known for its thirteenth-century Gothic cathedral. On 27 November 1870, it was the site of the Battle of Amiens in the Franco-Prussian War of 1870–71. The 1918 Battle of Amiens marked the beginning of the Allies’ Hundred Days Offensive in the First World War.
These are actually a set of individual wars that sometimes overlap, succeed, or run parallel to each other. Image: Jacques-Louis David, Napoleon Crossing the Alps (1800), Kunsthistorisches Museum.

Historians do not agree on the exact beginning or end of the wars. November 9, 1799 is an early candidate since that is when Napoleon seized power in France. Hoping to ease the difficulty, historians date by isolated wars. They disarticulate the Napoleonic Wars in a linear series:
War of the Second Coalition 1798-1802
War of the Third Coalition 1805
War of the Fourth Coalition 1806-7
War of the Fifth Coalition 1809
War of the Sixth Coalition 1812-14
War of the Seventh Coalition 1815
The successive numerical coordinates for the Coalitions offer regularity, but that regularity is undercut by the shifting make-up of that Coalition (sometimes Prussia was in, sometimes not; sometimes Russia, sometimes not) and by the discontinuity and ambiguity of the dates.
The Franco-Prussian War was fought from 19 July 1870 to 10 May 1871. The war ended with the defeat of Napoleon III and the unification of Germany; Italy gained the Papal States and Rome became the capital of Italy.
