Life

After the death of his father in 1287, John succeeded him as ruler of the Anhalt-Bernburg, but he had to rule jointly with his third brother, Bernhard II. The second brother, Albert, became a priest and renounced all his rights. Of the two youngest brothers, Henry also was ordained as priest and renounced his rights, whereas Rudolf was possibly dead by the time of his father's death.

John died unmarried and childless after four years of rule. He was succeeded by his brother Bernhard II, who became sole ruler.
