Walram II of Nassau (German: Walram II. von Nassau; c. 1220[1] – 24 January 1276) was Count of Nassau and is the ancestor of the Walramian branch of the House of Nassau.
Walram and Otto divided their county on 16 December 1255 with the river Lahn as border. The division treaty is nowadays known as the Prima divisio. The area south of the Lahn: the lordshipsWiesbaden, Idstein, the ÄmterWeilburg (with the Wehrholz) and Bleidenstadt, was assigned to Walram.[4]Nassau Castle and dependencies (Dreiherrische),[5] the ÄmterMiehlen and Schönau (Schönau Abbey near Strüth über Nastätten)[6] as well as the Vierherrengericht,[7]Laurenburg Castle, the Esterau (which was jointly owned with the counts of Diez) and the fiefs in Hesse remained jointly owned.[4]
Later, perhaps shortly after the conclusion of the division treaty, Walram expressed dissatisfaction with some provisions of the treaty and challenged them. Whether he was already acting under the influence of the mental illness from which he suffered is unknown. What is certain is that in an attack of insanity he burned his copy of the division treaty.[8]
Walram lost several towns, including Niederlahnstein, Pfaffenhofen and Vallendar, to the Archbishop of Trier. He also continued the Dernbacher Feud against Hesse. He died – allegedly in mental derangement – on 24 January 1276. He was succeeded by his son Adolf.
^Castle and Amt Nassau bore the name Dreiherrische because until 1778 it was jointly owned by the Ottonian branch and two sub-branches of the Walramian branch (Nassau-Usingen and Nassau-Weilburg). See: Huberty, et al. (1981).
^The Ämter of Miehlen and Schönau remained jointly owned until 1303, after which they were transferred to the Walramian branch and both sub-branches owned them jointly until 1778. See: Huberty, et al. (1981).
^The Vierherrengericht was named after its four owners, the counts of Katzenelnbogen (Hessen), Diez (Nassau-Diez), Nassau-Usingen and Nassau-Weilburg. In 1774 these areas, around the city of Nastätten and composed of thirty-eight villages, were divided. See: Huberty, et al. (1981).
