John II of Rietberg
|Died||11 December 1562|
|Spouse(s)||Agnes of Bentheim-Steinfurt|
|Father||Otto III, Count of Rietberg|
After his uncle Balthasar Oomkens von Esens died in 1540 without a male heir, John and his mother inherited the East Frisian Lordship of Harlingerland and John assumed the title of Lord of Esens, Stedesdorf and Wittmund.
In 1556, John illegally beheaded one of his own his officials in Rietberg and schemed against the victim's relatives. The relatives fled to the neighbouring County of Lippe. From there, they and a few faithful raided Rietberg. John then moved his mercenaries from Esens to Rietberg and attacked Count Bernhard VIII of Lippe. The army of Lippe responded by laying siege to the town of Rietberg. The Bishopric of Paderborn joined the attack on Rietberg. Lippe, Paderborn and East Frisia also sued each other in the court of the Lower Rhenish-Westphalian Circle. The Court found John guilty of a breach of the peace.
John refused to give in. Imperial troops joined the siege of Rietberg and in June 1557, the city was starved and had to capitulate. John was taken prisoner. Initially, he was held at the Imperial castle at Büderich (near Wesel); in 1560, he was transferred to Cologne, where he died in captivity in 1562 and was buried.
His pugnacity and power struggles earned him he nickname "John the Mad".
Marriage and issueEdit
John married Countess Agnes of Bentheim-Steinfurt. They had two daughters:
- Armgard (died: 1584), Countess of Rietberg, married: Count Simon VI of Lippe
- Walburgis (born: c. 1557 in Rietberg – died: 26 May 1586 in Esens), Countess of Harlingerland, married Count Enno III of East Frisia
John II was thus the last male ruler of Rietberg from the Werl-Arnsberg-Cuyk family. After his death, his widow acted as regent for his daughters until 1557, when the inheritance was divided: Armgard received Rietberg and Walburgis received the Harlingerland.
