"Rainald of Dassel (c. 1120 – 14 August 1167) was Archbishop of Cologne and Archchancellor of Italy from 1159 until his death. A close advisor to the Hohenstaufen emperor Frederick Barbarossa, he had an important influence on Imperial politics, mainly in the Italian conflict of Guelphs and Ghibellines." - (en.wikipedia.org 08.11.2019)
