The Balt(h)i dynasty, Baltungs, Balthings, or Balth(e)s, existed among the Visigoths, a Germanic tribe who confronted the Western Roman Empire in its declining years. The Balti took their name from the Gothic word balþa (baltha; bald or bold). It thus meant "the Bold ones" or "Bold men".
History
The Balti were considered next in worth among Gothic fighters, and next in royal dignity, to the Amali. But it was Alaric the Visigoth, a Balth, who led his people to the sacking of Rome in 410 CE and founded a dynasty that would come to rule much of Roman Gaul for a century and all of Roman Hispania for longer, establishing a kingdom in the latter that would last until early in the eighth century.
The Balti dynasty of Visigothic kings reigned from 395 to 531.
Edward Gibbon in footnote 4, Chapter 30, of the History of the Decline and Fall of the Roman Empire, adds:
