Events

By place

Byzantine Empire

• Byzantine Emperor Manuel I Komnenos asks Venice to help pay the costs of defending Sicily, whose Norman rulers have had good relations with Venice. Doge Vitale II Michiel refuses to pay the requested subsidy. Manuel begins to cultivate relationships with the main commercial rivals of Venice: Genoa and Pisa. He grants them their own trade quarters in Constantinople, very near the Venetian settlements.

Europe

• May 7 – King William I ("the Wicked") of Sicily dies at Palermo after a 12-year reign. He is succeeded by his 12-year-old son William II ("the Good"), whose mother, Margaret of Navarre, will be regent until he comes of age.
• July 5 – The town of Bad Kleinkirchheim (in modern Austria) is first mentioned, in an ecclesiastical document, in which Archbishop Conrad II of Salzburg confirms the donation of a chapel, nearby Millstatt Abbey.
• Autumn – Holy Roman Emperor Frederick Barbarossa begins his fourth Italian campaign, hoping to secure the claim of Antipope Paschal III in Rome and the coronation of his wife Beatrice I, Countess of Burgundy, as Holy Roman Empress.
• Mieszko III the Old proclaims a Prussian crusade against the pagans and pressures the collaboration of Frederick I. He leaves Greater Poland in the hands of his younger brother Casimir II the Just.
• Henry the Lion, duke of Saxony, has the Brunswick Lion created at Dankwarderode Castle in Braunschweig (modern Germany). (Mentioned by Albert of Stade, a German abbot and chronicler, as the year of origin.)

British Isles

• Summer – Henry II of England invades and conquers Brittany to punish the local Breton barons. He grants the territory to his 7-year-old son Geoffrey.
• Henry II enacts the Assize of Clarendon, reforming English law, influential in the development of jury trial in common law countries worldwide.
• Cartae Baronum ("Charters of the Barons"), a survey commissioned by the English Treasury requiring each baron to declare how many knights he had enfeoffed.
• Muirchertach Mac Lochlainn, High King of Ireland, is killed. He is succeeded by Ruaidrí Ua Conchobair, king of Connacht, who defeats Diarmaid mac Murchadha (or Dermot, another ruler in eastern Ireland) in battle. Diarmaid is exiled and goes to Normandy and the court of King Henry II of England to ask for assistance in retaking his kingdom. Henry gives him permission to find a willing army from either England or Wales. Richard de Clare, 2nd Earl of Pembroke ("Strongbow") and his half-brothers Robert FitzStephen and Maurice FitzGerald, Lord of Lanstephan, agree to help Diarmaid mac Murchadha in return for Diarmaid's daughter's hand in marriage.
• Anglo-Norman soldier William Marshal is knighted while on campaign in Normandy; he will be described as "the greatest knight that ever lived".
