Byzantine Empire[edit]


  • Spring – King Adalbert II returns to the mainland of Italy, and occupies the environs of Spoleto. Emperor Otto I ('the Great') leaves Rome with his army, and lays siege to the fortress city of Spoleto.
  • Otto I proceeds on campaign in Italy, remaining in the environs of Lucca. In the fall he leaves plague-wracked Tuscany, and is forced to retreat to Liguria. His rearguard is attacked by Adalbert II.

By topic[edit]


  • February – Pope John XII returns with his supporters to Rome. He convenes a synod that deposes Antipope Leo VIII who finds refuge at the court of Otto I. John dispatches a delegation under Otgar, bishop of Speyer, to negotiate an agreement.
  • May 14Pope John XII dies (rumoured to be by apoplexy, or at the hands of a cuckolded husband, during an illicit sexual liaison) after a 9-year reign. The Romans elect Benedict V, who is acclaimed by the city militia. He begins his pontificate as the 131st pope of the Catholic Church.
  • June 23 – Benedict V is deposed and ecclesiastically degraded after Otto I besieges Rome. He starves the Romans into submission and restores Leo VIII to the papal throne.
