Lantfrid

Lantfrid (also Landfrid or Lanfred, Latinised Lantfridus or Lanfredus) (died 730) was duke of Alamannia under Frankish sovereignty from 709 until his death. He was the son of duke Gotfrid. Lantfrid's brother was Theudebald.

Following Gotfrid's death in 709 and the accession of Lantfrid and his brother Theudebald, the Frankish maior domus Pepin of Herstal invaded Alamannia and fought against yet another duke, Willehari, whose territory was restricted to the Ortenau in western Alamannia. This campaign can be seen as an attempt by Pepin to impose royal authority on the duchy following the death of Gotfrid and also to assert his right to influence or even control the succession within the duchy. Pepin’s campaign against Willehari might therefore have taken place to assist Lantfrid and Theudebald in their claim to the duchy. However, both Lantfrid and Theudebald were hostile to Pepin’s successor.

After Pipin’s death in 714, Lantfrid dissolved all links with the royal court and its new maior domus Charles Martell.
