Politics and world history
Holy Roman Empire / Italy
- February to April: Frederick I Barbarossa besieges the city of Tortona on his Italian expedition , which is in conflict with the king-friendly Pavia . Captured Tortonese are publicly executed as a deterrent and the drinking water is poisoned with corpses and sulfur. The increasingly critical supply forces the city to seek peace and ultimately to submit . The emperor then promised that the city would not be damaged. Contrary to this promise, Tortona is destroyed by Pavia the next day.
- June 18 : Friedrich Barbarossa is crowned Roman-German Emperor in Rome by Pope Hadrian IV . Shortly before, Friedrich rejected the offer of the Roman Senate to receive the imperial crown from the hand of the Roman people. Then, during the coronation, the Romans attacked the Angel's Bridge and in northern Trastevere , but they could be repulsed. However, the summer heat and supply problems soon force Friedrich to retreat. The planned campaign against the Normans is broken off without having achieved anything. As a result, Barbarossa cannot keep his promises from the Constance Treaty . Further conflicts with the Pope are therefore foreseeable. On the way back, the emperor imposed the ban on Milan in Verona after the latter refused to submit to imperial jurisdiction. Via Regensburg the way goes to Christmas to Worms , which is developing into an important center of power under the Hohenstaufen .
- The termination of the Italian expedition led to a change in the political situation in Italy. As a result of the non-compliance with the Constance Treaty, the Roman Curia seeks the protection of its rights independently of the Empire and starts negotiations with the Normans in southern Italy .
- Bari rises against the Norman rule under William I of Sicily and negotiates with the Byzantine Empire .
- King Baldwin III of Jerusalem conquered Tartosa from Nur ad-Din and surrendered the city to the Knights Templar in 1157 .
