Notes

^ The Third Coalition was not established until April–September 1805; before then, the United Kingdom of Great Britain and Ireland fought the French First Republic and its allies on its own.^[1]
^ The French First Republic transformed into the First French Empire by the Constitution of 18 May 1804; the Coronation of Napoleon (a formality) would follow on 2 December 1804.
^ The Austrian Empire was proclaimed on 11 August 1804 by Francis II (who inherited the Archduchy of Austria and thereby the Habsburg monarchy on 1 March 1792, and was elected Holy Roman Emperor on 5 July 1792), who thereby also assumed the hereditary title of Austrian Emperor tied to the House of Habsburg. On 6 August 1806, Francis II abdicated as Holy Roman Emperor and effectively dissolved the Holy Roman Empire. In the meantime, the Imperial and Royal Army was officially still the Army of the Holy Roman Empire (not to be confused with the Imperial Army (Holy Roman Empire)), but in practice consisted entirely of Habsburg troops in the service of the Austria Empire.
^ Russian general Kutuzov was in overall command of the Coalition forces at Austerlitz, but the c. 60,000 Austrian troops outnumbered the c. 15,000 Russian troops.
