Duchy of Westphalia
Engelbert II succeeded his father in 1308 and continued his father's efforts to maintain authority over the County of Mark. This necessitated conflict with Bishop Ludwig II of Münster, as well as the Archbishop of Cologne, Henry II of Virneburg, who also dominated the neighboring Duchy of Westphalia. When Bishop Ludwig II marched into Hamm in 1323, he fell into Engelbert's hands and was released only after paying 5,000 silvermarks, a very high ransom.
