Pepin of Herstal was a Frankish statesman who served as the Mayor of the Palace in the 7th century. He was born around 635 and played a crucial role in the Merovingian dynasty's politics, effectively ruling on behalf of the kings. His leadership helped consolidate power in the Frankish realm and laid the groundwork for future Carolingian rulers. Pepin's most significant achievement was the unification of the Frankish territories, which he accomplished through military campaigns and strategic alliances. He is also known for his support of the Christian Church, which strengthened his influence and helped establish the Carolingian dynasty that would later be led by his grandson, Charlemagne.
