Mechtild of Nassau

Mechtild of Nassau (before 1280 – 19 June 1323) was the youngest child of Adolf of Germany and his wife Imagina of Isenburg-Limburg. Mechtild is also known as Matilda of Nassau. She was Duchess consort of Bavaria, by her marriage to Rudolf I, Duke of Bavaria.


Mechtild's paternal grandparents were Walram II of Nassau and his wife Adelheid of Katzenelnbogen. Her maternal grandparents were Gerlach IV of Isenburg-Limburg and his wife Imagina of Blieskastel.

Mechtild was the youngest of eight children, however only Mechtild and three other siblings lived to adulthood: Gerlach I of Nassau-Wiesbaden, Walram III of Nassau-Wiesbaden and Adelheid, Abbess of Klarenthal Abbey.

Her great-grandmother, Matilda of Guelders, was a daughter of Otto I, Count of Guelders and Richardis of Bavaria. Richardis was daughter of Otto I of Wittelsbach, Duke of Bavaria and his wife Agnes of Loon.


She married in Nuremberg 1 September 1294 Rudolf I, Duke of Bavaria.[1] John I of Isenburg-Limburg helped make the final agreement.

Rudolf succeeded his father in 1294 and supported his father-in-law king Adolf of Nassau-Weilburg against his uncle, the Habsburg Albert of Austria. After Adolf’s death Rudolf joined Albert’s party but the strong dynastic policy of the new king caused a new conflict. Rudolf's mother, Matilda of Habsburg acted as regent for her son Rudolf as well as her other son, the future Louis IV, Holy Roman Emperor. A civil war against Louis due to new disputes on the partition of Bavaria was ended in 1313, when peace was made at Munich.

Mechtild and Rudolf had six children:

  1. Ludwig (1297 – before 5 April 1311)
  2. Adolf, Count Palatine of the Rhine (27 September 1300, Wolfratshausen – 29 January 1327)
  3. Rudolf II the Blind (8 August 1306, Wolfratshausen – 4 October 1353, Neustadt)
  4. Rupert I the Red (9 June 1309, Wolfratshausen – 16 February 1390)
  5. Mathilde (1312 – 25 November 1375), married 1330/1 to Count John III of Sponheim
  6. Anna (1318–1319).

Rudolf died in 1319, in England.

Louis IV, Holy Roman Emperor had taken the Palatinate by force of arms. In August 1322, the war finally came to an end, but only after Mechtild's death in June 1323, when the three brothers finally were able to make peace with their uncle. Louis' sons inherited Bavaria and Rudolf and Mechtild's sons inherited the Upper Palatinate and the Palatinate in line with the Treaty of Pavia.

Metchild died 19 June 1323 in Heidelberg. She was buried at Klarenthal Abbey.[2]
