Original prompt & settings (JSON) ↗Wilhelm wanted “Emperor of Germany” and disliked the title he got. The Grand Duke of Baden escaped the quarrel by acclaiming only “Kaiser Wilhelm.”
18 January 1871, inside the siege lines
While Paris was under siege, on 18 January 1871, Wilhelm I of Prussia was ceremonially proclaimed German Emperor in the Hall of Mirrors at Versailles. Otto von Bismarck read the imperial proclamation before the assembled German princes, officials, officers and soldiers.
The 1,391 people present were overwhelmingly from the army besieging the city. The date fell exactly 170 years after the Hohenzollern coronation of 1701.
A title nobody could agree on
Wilhelm accepted the adjectival “German Emperor” reluctantly; he had preferred “Emperor of Germany.” Bismarck recalled that the dispute drove Wilhelm to tears shortly before the ceremony, and that Wilhelm then pointedly ignored him.
Grand Duke Friedrich I of Baden closed the ceremony with a cheer for “Kaiser Wilhelm,” deliberately avoiding both contested formulations.
The law was already elsewhere
The ceremony made no constitutional change. The November 1870 accession treaties had brought Bavaria, Württemberg, Baden and southern Hesse into the enlarged federation effective 1 January, and the provisional constitution had been in force since then. The definitive Imperial Constitution was enacted on 16 April and took effect on 4 May 1871.
This was a dynastic and military ceremony, not a popular constituent assembly: Wilhelm was proclaimed, not crowned or elected. The Hall of Mirrors returned to use as a military hospital the following day.

What the sources leave uncertain
- The date and ceremony are secure. What requires qualification is the phrase “founding of the empire”: the federal union was legally in place on January 1, while January 18 was its symbolic proclamation.
- The definitive Imperial Constitution was enacted on April 16 and took effect on May 4, 1871; it was not the legal act performed at Versailles.
