Otto I, king of the Germans, had beaten back the Magyar raiders at the Lechfeld in 955 and made himself master of northern Italy. When Pope John XII was threatened by the Italian king Berengar, he called on Otto for help. Otto came to Rome and was crowned emperor by the pope on 2 February 962, reviving the western imperial title that Charlemagne had held. Days later the two agreed the Privilegium Ottonianum, setting out the rights of emperor and pope. The empire Otto founded, later called the Holy Roman Empire, lasted until 1806.
