Henry I of Mulnarken (German: Heinrich I von Mulnarken) (1190 - 1238) was the Archbishop of Cologne from 1225 until 1237.

Early lifeEdit

Not much is known of Henry's life before being elected Archbishop. Before he was appointed Provost in Bonn, he went by the surname "Leinenhose".

Archbishop of CologneEdit

Henry of Mulnarken was elected Archbishop of Cologne on 15 November 1225, one week after the murder of the previous archbishop, Engelbert I of Berg. Henry set out immediately to punish the conspirators in the murder, and he received necessary rights and equipment from the Holy Roman Emperor Frederick II Stupor Mundi and Pope Honorius III. A bounty of 2,000 silver marks was placed on the head of the lead conspirator Frederick I of Isenberg, and his castles were besieged and captured. After travelling to Rome to have his excommunication lifted, Frederick was captured in Liège and sold to Cologne, where he was executed on 14 November 1226 at the Severin Gate.

Henry of Mulnarken continued the policy of his predecessors to increase the power and territories of the Archbishopric. He entered into long and costly conflicts with the Dukes of Marck and Cleves, and the city of Cologne. He was forced to concede the weakness of the Prince-Bishopric, and he had to recognise municipal rights on several Westphalian towns. Despite the temporal failures of Henry's reign, spiritually Cologne flourished. Excommunication occurred in 1233. Henry was interred in Cologne Cathedral after his death.
