Pepin of Landen was a prominent nobleman in the early medieval period, known for his role in the Frankish kingdom during the 7th century. He served as the mayor of the palace for the Merovingian kings, a position that allowed him to wield significant political power. His influence helped shape the future of the Frankish state. Pepin was also the father of Grimoald, who continued his legacy. He is often associated with the rise of the Carolingian dynasty, which would later dominate much of Western Europe. Pepin's contributions laid the groundwork for the eventual transition from Merovingian to Carolingian rule.
