Mayor of the Palace
The last Merovingian kings, known as the "lazy kings" ("rois fainéants"), did not hold any real political power, while the Mayor of the Palace governed instead. When Theuderic IV died in 737, Mayor of the Palace Charles Martel left the throne vacant and continued to rule until his own death in 741. His sons Pepin and Carloman briefly restored the Merovingian dynasty by raising Childeric III to the throne in 743. In 751, Pepin deposed Childerich and acceded to the throne.
