William II, Landgrave of Hesse

William II was Landgrave of Lower Hesse from 1493 and Landgrave of Upper Hesse after the death of his cousin, William III, Landgrave of Upper Hesse in 1500. This immediately sparked the War of the Katzenelnbogen Succession, in which William sought to enforce his claim on the County of Katzenelnbogen with military might.
