His father, Christian II, had ruled jointly with his uncle, Otto I. After Christian II died in 1233, Otto I acted as guardian for the underage John I. When John I came of age, he ruled jointly with Otto I. After Otto I died in 1251, John I ruled alone.
In 1258 and 1259, he fought in the Bremen Prince-Archbishopric Feud on the side of his cousin Hildebold of Wunstorf against Rüstringen, Östringen and Stedingen. When the feud had ended, he kept the territories he had conquered.
Like his predecessors, he had many disputes with his relatives, the Counts of Oldenburg-Wildeshausen. Ultimately, their county was divided between the bishops of Münster and Bremen. This resulted in Oldenburg and Delmenhorst being almost completely surrounded by these territories, and led to centuries of disputes between the Counts of Oldenburg and the two Prince-Bishops.
Marriage and issueEdit
He married Richeza, a daughter of Count Henry II of Hoya, and had the following children:
