By place[edit]



  • English warships (nine vessels from Alfred's new fleet) intercept six Viking longships in the mouth of an unknown estuary on the south coast (possibly at Poole Harbour) in Dorset. The Danes are blockaded, and three ships attempt to break through the English lines. Lashing the Viking boats to their own, the English crew board the enemy's vessels and kill everyone on board. Some ships manage to escape, two of the other three boats are driven against the Sussex coast. The shipwrecked sailors are brought before King Alfred the Great at Winchester and hanged. Just one Viking ship returns to East Anglia.[1]

  • January – The Cadaver Synod: Lambert II orders Stephen VI to exhume the nine-month-old cadaver of former pope Formosus, to redress him in papal robes, and have him put on trial while seated in a chair at St. Peter's. Formosus is 'convicted' of several crimes, his fingers of consecration are cut off, and the body is stripped of his vestments.
  • August – Stephen VI is removed from office, imprisoned and strangled in his cell. He is succeeded by Romanus as the 114th pope of the Catholic Church.
  • December – Romanus is deposed and succeeded by Theodore II as the 115th pope of Rome, but dies twenty days later.
