Corona de Hierro
Travelling down via Verona, Modena, and Bologna, he eventually arrived at Milan where he received the Iron Crown of Lombardy and the title of King of Italy in 1208. He was met at Viterbo by Pope Innocent and was taken to St. Peter's Basilica, where he was crowned emperor by Pope Innocent on 21 October 1209, before rioting broke out in Rome, forcing Otto to abandon the city.
