Lantfrid
Lantfrid was a duke of Alemannia who reigned in the late 8th century. He succeeded his father, Theuderic, as duke. Lantfrid's reign was marked by conflict with the Frankish kingdom. He asserted his independence from Frankish overlordship, leading to military confrontations. Despite the challenges, Lantfrid managed to maintain a degree of autonomy for Alemannia during his rule. He is also known for his association with his brother, Theudebald, with whom he may have shared power or co-ruled. The exact nature of their relationship and division of authority is not entirely clear from historical records. Lantfrid's efforts to solidify Alemannic power were eventually curtailed by the rising influence of Charlemagne, the Frankish king. Charlemagne ultimately subdued the Alemanni and integrated their territory more firmly into the Frankish realm. Lantfrid's legacy is primarily tied to his role as a leader during a period of transition and conflict for the Alemannic duchy, struggling for its independence against a powerful and expanding Frankish empire. His exact death date is not precisely known, but he was deceased by 789 when Charlemagne was definitively in control of Alemannia.
