1160

Year 1160 (MCLX ) was a leap year starting on Friday of the Julian calendar.

• Spring – Emperor Manuel I Komnenos sends an embassy led by John Kontostephanos to Jerusalem, to ask King Baldwin III to nominate one of the princesses of the Crusader states, as a bride for the widowed emperor. Their two candidates are 15-year-old Maria of Antioch, and Melisende of Tripoli. Baldwin suggests Melisende, and her brother Count Raymond III sets about gathering an enormous dowry. The ambassadors are not satisfied, and delay the marriage for over a year. They hear rumours about Melisende's birth, based on her mother's (Countess Hodierna of Jerusalem) infidelity, and therefore Melisende's possible illegitimacy.^[1] In the end, the Emperor marries Maria in 1161 and Melisende eventually enters a convent.

• January 25 – Frederick Barbarossa, Holy Roman Emperor, captures Crema, Lombardy after a 6-month siege, as part of his campaign against the independent Italian city-states. Some 20,000 survivors are allowed to leave the city with whatever they could carry before Crema is looted and burnt to the ground.^[2] The expense of the siege (over 2,000 silver marks) and Frederick's determination to enforce it over the winter, demonstrates his ability to hold troops in the field and to keep his allies on side.^[3]
• May 18 – Erik IX Jedvardsson of Sweden is murdered, after which his murderer Magnus Henriksen proclaims himself king of Sweden as Magnus II. He is murdered in turn the following year, however. Erik is soon worshipped as a saint. Though never formally canonized by Pope Alexander III, he eventually becomes the patron saint of Sweden.

• A plot of land at Miholjanec is donated to the Knights Templar, who build a monastery in nearby Zdelia. This is the earliest historical mention of the Templars in Croatia and Hungary.^[5]
• Spital am Semmering (modern Austria) is founded by Margrave Ottokar III. He erects a hospital and completes the colonization of the area around the Traisen and Gölsen rivers.

• Autumn – Raynald of Châtillon, prince of Antioch, makes a plundering raid in the valley of the Euphrates at Marash to seize cattle, horses and camels from the local peasants. On his way back to Antioch, he and his retinue are attacked by Zangid warriors. Raynald is unhorsed, captured and sent to Aleppo where he is put in jail.^[1]
