The Holy Roman Empire existed for over a millennium, spanning from 800 to 1806.1

Its origins are traced to the year 800, when Pope Leo III crowned the Frankish king Charlemagne as "emperor of the Romans" on December 25. While the empire traces its beginnings to this event, the specific title "Holy Roman Empire" did not formally appear until the 13th century during the conflict between the Hohenstaufen dynasty and the papacy.231

The empire officially came to an end on August 6, 1806, when the last Holy Roman emperor, Francis II, formally dissolved the institution and laid down the imperial crown amidst the Napoleonic Wars.456
