## Events
### By place
#### Byzantine Empire

* August – King William II of Sicily ("the Good") lands in Epirus with a Siculo-Norman expeditionary force of 200 ships and 80,000 men (including 5,000 knights) and marches as far as the Byzantine city of Thessaloniki, which he takes and pillages, massacring some 7,000 Greek citizens.
* September 11–12 – Isaac II Angelos leads a revolt in Constantinople and deposes Emperor Andronikos I Komnenos. Andronikos tries in vain to flee across Asia but is captured and killed by an angry mob. Isaac is proclaimed emperor, ending the Komnenos Dynasty.
* November 7 – Battle of Demetritzes: A reinforced Byzantine army under Alexios Branas decisively defeats William II, ending his invasion of the Byzantine Empire. Thessaloniki is recaptured, and the Normans are pushed back to Italy. Many Norman ships are lost to storms.
* Uprising of Asen and Peter: Peter and Ivan Asen lead a revolt of the Vlachs and Bulgars against the Byzantine Empire, eventually establishing the Second Bulgarian Empire.

#### Levant

* March 16 – The 23-year-old Baldwin IV of Jerusalem ("the Leper King") dies of leprosy after a 10-year reign. He is succeeded by his 8-year-old nephew, Baldwin V, as the sole ruler of Jerusalem under the regency of Count Raymond of Tripoli. The child-king becomes a pawn in the politics of the kingdom, between his mother Sibylla of Jerusalem (sister of Baldwin IV) and her younger half-sister Isabella I.
* Saladin agrees to a 4-year truce due to severe drought and famine which has struck Palestine. The treaty is signed by Count Raymond of Tripoli and important nobles from Jerusalem. Commerce is renewed between the Crusader States and their Muslim neighbors. A flow of corn from the east saves the Crusaders and the population from starvation.

#### British Isles

* April 25 – John's first expedition to Ireland: King Henry II of England knights his son and heir, the 18-year-old Prince John, newly created Lord of Ireland, and sends him to Ireland, accompanied by 300 knights and a team of administrators to enforce English control. Landing at Waterford, he treats the local Irish rulers with contempt, making fun of their unfashionable long beards. Also failing to make allies amongst the Anglo-Norman settlers, the English army is unable to subdue the Irish fighters in unfamiliar conditions and the expedition soon becomes a complete disaster. In December, John returns to England in defeat. Nonetheless, Henry gets him named 'King of Ireland' by Pope Urban III and procures a golden crown with peacock feathers.
* April 15 – 1185 East Midlands earthquake occurs. It is the first earthquake in England for which there are reliable reports indicating the damage, which includes destruction of Lincoln Cathedral.

#### Europe

* July – Treaty of Boves: King Philip II of France signs a treaty to ensure his authority over his vassals, with Amiénois, Artois and other places in northern France passing to him. Philip is given the nickname "Augustus" by the monk Rigord for augmenting French lands.
* August 15 – The cave monastery of Vardzia is consecrated by Queen Tamar of Georgia. She marries Yury Bogolyubsky, Grand Prince of Novgorod.
* September – Henry the Lion, duke of Saxony, returns to Germany after being banished for three years by Frederick Barbarossa, Holy Roman Emperor.
* December 6 – King Afonso I of Portugal ("the Great") dies after a 36-year reign. He is succeeded by his son Sancho I ("the Populator") as ruler of Portugal.
* Igor Svyatoslavich's failed campaign against the Cumans, later immortalized in The Tale of Igor's Campaign, takes place this year.

* April 25 – Battle of Dan-no-Ura: The Japanese fleet (some 300 ships) led by Minamoto no Yoshitsune defeats the fleet of the Taira clan in the Shimonoseki Strait.
