John II, Count of Holstein-Kiel

John II, nicknamed the one-eyed (1253–1321) was the ruling count of Holstein-Kiel from 1263 to 1316.

Life
He was younger of the two sons of Count John I, from the Kiel line of the House of Schauenburg.

He divided the county with his uncle, Count Gerhard I of Holstein-Itzehoe and his elder brother, Count Adolphus V of Holstein-Segeberg, meant to be the secundogeniture for Holstein-Kiel. John II received the area between the Kiel Fjord and the sources of the Alster and the Pinnau. He took up residence at Kiel Castle. He was a hapless ruler.

In 1308 his second-born son Adolphus VII succeeded John II's brother Adolphus V in Holstein-Segeberg. After the violent death of his two sons, Adolphus VII and Christopher in 1313 and 1315 respectively, his grand-nephews John III of Holstein-Plön and Gerhard III of Holstein-Rendsburg appropriated most of his territory. He lived until his death from the revenues of the city of Kiel and its surroundings.

His nickname refers to an accident where he lost the sight in one eye after an unfortunate throw of a chicken bone by his court jester.
