Otto I of Nassau
From Wikipedia, the free encyclopedia
Otto I of Nassau (ca. 1247–1290), Count of Nassau. He was the younger son of Count Henry II of Nassau and Matilda of Geldern.
Otto I became the count of Dillenburg, Hadamar, Siegen, Herborn and Beilstein after many years of quarrel with his brother Walram II and the division of 17 December 1255 and received possessions north to the Lahn. And thus the geographical and political separation began for a long time. He became the founder of the Otto's line of House of Nassau. He stood against the local aristocracy, particularly the counts of Greifenstein and of Dernbach and was for many years banished, since he withheld lands of Teutonic Knights, which his uncle had left to him. His opponents were among other the archbishops of Cologne and Trier, which presented the territorial claims and he lost also the lordships in Emsland and Koblenz.
He married Agnes von Leiningen, daughter of Count Emich IV of Leiningen and had following children:
- Henry of Nassau-Siegen (d. 1343), Count in Siegen, Ginsberg, Haiger and in Westerwald since 1303, in Dillenburg, Herborn and Beilstein in 1328-43.
- Emicho I of Nassau-Hadamar (d. 7 June 1334) in Driedrof, Estenau and Hadamar.
- John of Nassau-Dillenburg (d. 1328), Count in Beilstein and Herborn since 1303, in Katzenelnbogen since 1320.
- Mechtild (d. 28 October 1319), married ca. 1289 tp Gerhard von Schönecken.
- Gertrud (d. 19 September 1359), Abbess of Altenberg.
Also he had illegitimate son Heinrich, who was a monk in Arnstein and a priest in Nassau.
