Johann was last Count of Cleves, from 1347 through 1368. Upon his death in 1368, the counties of Cleves and Count of Mark were united.
He married Mechteld of Guelders († 1384), daughter of Reginald II, Duke of Guelders, but the marriage remained childless. After his death, the County of Cleves went to Adolf III of the Marck and so to the Counts of Marck.
