Protadius (died 606) was the mayor of the palace of Burgundy from 604, when he displaced his rival Berthoald, until his death two years later.
She, however, desired to raise him to status in the kingdom and had him given the patricianship over the lands east of the Jura, whose duke, Wandalmar, had died in 604.
Attacked by Clotaire II of Neustria's son, Merovech, and his mayor, Landric, Berthoald died in the ensuing battle when he realised that he had nothing to lose, for he was no longer safe at court.
Perhaps frightened by the same schemes which had ensured his elevation, he undermined the nobility to secure his position and was an exceedingly cruel extortionist.
At the palace of Quierzy, Theuderic assembled the army, but the men did not want to fight their countrymen and the Duke of Alemannia, Uncelen, declared that the king ordered Protadius' death.
