Bertachar

Bertachar (or Berthachar) was a king of Thuringia from about 510 until about 525, co-ruling with his brothers Hermanfrid and Baderic.

Bertachar was probably not a Thuringian himself. Frankish sources, such as Venantius Fortunatus, make the three brothers sons of King Bisinus. They are sometimes considered as sons of Bisinus' wife Menia, or else as sons of Basina, who is called a wife of Bisinus by the Frankish historian Gregory of Tours. Many scholars, however, reject Bisinus' marriage to Basina as ahistorical, leaving Menia as his only known wife.
