What happened in this minute
During Christmas Mass at Old St Peter's Basilica, Leo III placed a crown on Charlemagne's head and the congregation acclaimed him emperor of the Romans.
Einhard, Charlemagne's biographer, claimed the king was surprised and would not have entered the church had he known. Most historians read that as diplomacy: the coronation complicated relations with Constantinople, which still had an emperor.
The act created a precedent that shaped European politics for a millennium, that imperial legitimacy in the West was conferred by the papacy.
