Biography
Agnes was a daughter of Count Emich IV of Leiningen and his wife Elisabeth. [1] She married before 1270 [3] Count Otto I of Nassau (died between 3 May 1289 and 19 March 1290). [1] [2] Her husband had divided the County of Nassau with his elder brother Walram II on 16 December 1255, on which occasion Otto had obtained the area north of the river Lahn, containing, among others, Siegen, Dillenburg, Herborn, Tringenstein, Neukirch and Emmerichenhain. [4]
- "Ottho comes de Nassawen... cum uxore nostra Agnete nec non Henrico nostro primogenito" ("Otto Count of Nassau... with our wife Agnes and Henry our firstborn son") confirmed the gift of goods "in Hasilbach et Aldindorph" to the church in "Aldenburg" (sic, for Altenberg Abbey) made by "matrem nostram Methildim comitissam bone mem... cum sorore nostra Katherina ibidem locata" ("our mother the Countess Matilda of blessed memory... and our sister Catherine located in the same place") 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. [2]
Agnes ruled with her sons after the death of her husband. [2] [5] That can only mean that she acted as regent for her younger sons, the eldest two being of age at the death of their father. Nothing else is known about her regency.
On 13 April 1298 Agnes obtained permission from Bishop Emich I of Worms to found a monastery in Abenheim (today a part of the city of Worms). The current Klausenberg Chapel is probably the remains of that monastery. Agnes was a second cousin of the bishop. In 1299 she and her sons Henry and Emich confirmed the foundation in a charter. [6]
- "Agnes relicta quondam... dni Ottonis... comitis de Nassawe" ("Agnes widow of the former... lord Otto... Count of Nassau") gave property in "Herberin" to "Aldenburg" (i.e., Altenberg Abbey) "et... sororie [sic] nostre Dne Katerine et filie nostre Gertrudis" ("and ... [of] our sister the lady Catherine and our daughter Gertrude"), with the consent of "nostrorum filiorum.. Henrici, Emiconis militum, Ottonis et Iohannis clericorum" ("our sons, Henry and Emico, knights, and Otto and John, clerics"), in a charter dated December 1299. This is the last mention of Agnes in a charter. When she died is unknown. She had already died when her sons divided the County of Nassau after a long dispute in 1303. She was buried in Altenberg Abbey. [1] [2]
