On 1 March 1871 the Imperial German Army paraded through Paris to mark their victory in the Franco-Prussian War. The city had been under siege by Prussian forces since September 1870, with Prussia being unified into the German Empire on 18 January 1871. The Armistice of Versailles of 28 January ended hostilities, but the city remained in French hands. Preliminary peace terms were agreed in the 26 February Treaty of Versailles, which allowed 30,000 German troops to occupy Paris from 1 March until the treaty was ratified.
German troops entered the city at 8 am that day, marching down the Champs-Élysées and occupying the Place de la Concorde. They were followed by additional troops at 3 pm, who paraded down the Champs-Élysées with fifes and drums playing.
