Overview
Swanachild (also Swanahild or Serenahilt) was the second wife of Charles Martel.
Reign
Swanachild belonged to the clan of the Agilolfing, though her parentage is not quite clear. Her parents could be Tassilo II, duke of Bavaria, and his wife Imma. Alternatively, her parents could be Theudebert of Bavaria, duke of Bavaria and his wife Regintrud.
In the 720s Charles Martel married Swanachild. After an initial conflict, Martel established amicable relations with Bavaria.
The Reichenau Codex listed her as Suanahil regina.
