^ The term "Austrian Empire" came into use after Napoleon crowned himself Emperor of the French in 1804, whereby Francis II, Holy Roman Emperor took the title Emperor of Austria (Kaiser von Österreich) in response. The Holy Roman Empire was dissolved in 1806, and consequently "Emperor of Austria" became Francis' primary title. For this reason, "Austrian Empire" is often used instead of "Holy Roman Empire" for brevity's sake when speaking of the Napoleonic Wars, even though the two entities are not synonymous.

Saxony changed sides again in 1813 during the Battle of Leipzig, causing most other member-states to quickly follow suit and declare war on France.
