Events

By place

Byzantine Empire

Autumn – Emperor Manuel I Komnenos sets out from Constantinople at the head of an expeditionary army. He marches to Cilicia; and while the main army follows the coast road eastwards Manuel hurries ahead with a force of only 500 cavalry. He manages to surprise Thoros II "the Great", lord of the Armenian Kingdom of Cilicia, who participated in the attack on Cyprus in 1156. Thoros flees into the mountains and Cilicia is occupied by the Byzantines.

Europe

January 11 – Vladislav II becomes king of Bohemia. He is crowned by Frederick Barbarossa, Holy Roman Emperor, with a diadem (called by the chroniclers a diadema or circulus). Vladislaus is also invested with Upper Lusatia, and accompanies Frederick to Milan to suppress the rebellion in Lombardy (northern Italy).
The Diet of Roncaglia is convoked by Frederick I. He mobilises an army of 100,000 men and leaves in June for a second Italian expedition – accompanied by Henry the Lion and his Saxon forces. He crosses the Alps and lays siege to Milan. German forces capture the city from the rebels after a short siege. However Milan soon rebels again, with Empress Beatrice taken captive and forced into parading on a donkey.
Summer – King Henry II of England travels to France to meet King Louis VII and propose a marriage between his three-year-old son Henry and Louis' daughter Margaret (less than a year old). She is shipped to England, as the future wife and queen. The Vexin region is promised to Margaret as dowry and is put under the care of the Knights Templar, until her future husband is old enough to take control of it.
August 31 – King Sancho III ("the Desired") dies after a 1-year reign. He is succeeded as ruler of Castile by his 2-year-old son Alfonso VIII ("the Noble"). The noble houses of Lara and Castro claim the regency, as the boy's uncle, Ferdinand II (ruler of León and Galicia).
Raymond of Fitero, Spanish monk and abbot, pledges to defend the fortress of Calatrava (guarding the roads to Córdoba and Toledo) from incoming Muslim raiders. It is the founding moment of the Order of Calatrava, the spearhead of the Iberian armies during the Reconquista.
Portuguese forces, led by King Afonso I of Portugal ("the Great"), conquer Pamela, Alcácer do Sal and Sesimbra from the diminished Almoravids.
12-year-old William Marshal is sent from England to the Château de Tancarville in Normandy to be brought up in the household of William de Tancarville, a cousin of William's mother. He begins his training as a knight; this also includes academic studies, practical lessons in chivalry and courtly life, and warfare and combat (using wooden swords and spears).
Welsh forces under Ifor Bach ("Ivor the Short") attack Cardiff Castle and kidnap William Fitz Robert, Norman lord of Glamorgan, along with his family.

Asia

September 5 – Emperor Go-Shirakawa of Japan abdicates the throne after a 3-year reign. He is succeeded by his 15-year-old son Nijō as the 77th emperor. Go-Shirakawa retains power, and gives Kiyomori Taira a higher position to lead a samurai-dominated government.
