1186 (The People's Chronology)
The former procurator-general of Ireland Hugh de Lacy, 1st lord of Meath, inspects a castle that he is having built on the ruins of an ancient monastery that he has had demolished at Durrow, Leinster, and is decapitated July 15 by an assassin. A son of England's Henry II visited Ireland last year as lord of Ireland and complained to the king that Meath was conspiring against him.
A triple coronation takes place at Milan as Friedrich I Barbarossa is crowned king of Burgundy; his 21-year-old son Heinrich is crowned Caesar in a deliberate revival of the old Roman title; and Heinrich's 32-year-old Norman bride, Constance d'Hauteville, daughter of Sicily's late Roger II, is crowned queen of the Germans. Sent north by her illegitimate nephew William II to shore up relations between Sicily, the papacy, and the Holy Roman Empire, she has arrived with a troubadour knight and 150 mules carrying treasure.
Friedrich I Barbarossa takes the cross and prepares for a Third Crusade.
Bulgarian insurgents Ivan Asen and his brother Peter proclaim their independence after a violent quarrel with the Byzantine emperor Isaac II Angelus (see 1185). Ivan is crowned at Turnovo and will reign until 1196 as Asen I; his brother Peter rules the eastern half of the kingdom from Preslav. They invade Thrace, suffer a defeat, withdraw to the north, and gain Cuman support to conquer northern Bulgaria (see 1187).
The Kamakura period that will dominate Japan until 1333 begins under Minamoto leader Yoritomo, now 39, whose family is based in the village of Kamakura. His power derives in large part from that of his wife's father, Tokimasa Masako Ho (see 1189).
