"Philip I (German: Philipp von Heinsberg) (c. 1130 – 13 August 1191) was the Archbishop of Cologne and Archchancellor of Italy from 1167 to 1191.
He was the son of Count Goswin II of Heinsberg and Adelaide of Sommerschenburg. He received his ecclesiastic training in Cologne and Rheims, becoming dean of the cathedral chapter in Cologne and then provost of Liège. In late Summer 1167, he was raised to the archchancery and the archdiocese of Cologne, where he was consecrated 29 September 1168. In that year, he entered into and mediated the controversy between France and England.
As bishop, Philip continued the policies of his predecessors. He exceeded all of them, however, in his territorial expansions, buying up the lands of his vassals and selling many for a profit. Philip held his fief directly from the emperor and was the greatest of the imperial tenants-in-chief. By buying up his vassals' subvassals, he tied them closer to himself. Frederick Barbarossa, however, saw a threat in the archbishop's pretensions and allied himself to the competing baronial factions of the region, especially Henry IV of Luxembourg, who had a hereditary claim to the Hainaut. Barbarossa also made Aachen and Duisburg royal cities with trade privileges in order to weaken Cologne economically." - (en.wikipedia.org 26.06.2021)
