|Noble family||House of Nassau|

|Father||Henry II of Nassau|
|Mother||Matilda of Guelders and Zutphen|
Otto was the third son of Count Henry II of Nassau and Matilda of Guelders and Zutphen, the youngest daughter of Count Otto I of Guelders and Zutphen and Richardis of Bavaria (herself daughter of Otto I Wittelsbach, Duke of Bavaria). Otto is first mentioned in a charter from 1247.
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 north of the Lahn: the lordships Siegen, Dillenburg, Herborn, Tringenstein, Neukirch and Emmerichenhain, a part of the Kalenberger Zent (Amt Kalenberg), as well as Dietkirchen and (Bad) Ems, was assigned to Otto. Nassau Castle and dependencies (Dreiherrische), the Ämter Miehlen and Schönau (Schönau Abbey near Strüth über Nastätten) as well as the Vierherrengericht, Laurenburg Castle, the Esterau (which was jointly owned with the counts of Diez) and the fiefs in Hesse remained jointly owned.
Protecting and enforcing his rights in his country was not always easy for Otto, especially at a time when the power of the supreme patron in the empire had sunk deeply. Disputes with the lords of Westerburg and the counts of Sayn about prerogatives in the Westerwald, and with the lords of Greifenstein and the lords of Dernbach about executive powers, often led to feuds and struggles. The details of the course of these feuds are unknown. In his struggles with the Archbishop of Trier, Otto lost the Vogtei of Koblenz and of Ems.
Otto's relationship with Siegfried II of Westerburg, the Archbishop of Cologne, also remains unclear. Otto made a covenant with various lords in Westphalia on 8 April 1277 to wage war against the archbishop. But Otto was an ally of the archbishop in the War of the Limburg Succession.
Otto's attempt to reduce his father's rich gifts to the Teutonic Order, or at least not to increase them in accordance with the wishes of the Order, ensured that he was designated as a robber of the goods of the order in 1285, was excommunicated, and his county was put under interdict, until the dispute was settled the following year.
Otto founded the chapel in Feldbach before 1287. ʻOttho comes de Nassawen … cum uxore nostra Agnete nec non Henrico nostro primogenitoʼ confirmed the donation of ʻbonorum in Hasilbach et Aldindorphʼ to the church in Aldenburg (read: Altenberg Abbey) made by ʻmatrem nostram Methildim comitissam bone mem … cum sorore nostra Katherina ibidem locataʼ by charter dated 3 May 1289. This is the last mention of Otto, in a charter dated 19 March 1290, he is mentioned as deceased. He was buried in Altenberg Abbey. He was succeeded by his sons Henry, Emicho and John.
Marriage and childrenEdit

- 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).

- A wedding date is not mentioned anywhere. According to Dek (1970), the eldest son from the marriage was born around 1270, so the marriage must have taken place before 1270.
