Childeric III
After Charles Martel's death in 741, Carloman and Pepin the Short, his sons by his first wife Rotrude, became co-mayors of the palace.These revolts may have played a part in their decision to fill the throne with a Merovingian king after a six-year vacancy to add legitimacy to their reigns.[1] According to Einhard, Charlemagne's biographer, Childeric took little part in public business and would, once a year, be brought in an ox cart led by a peasant and preside at court on a throne, giving answers prepared by the mayors to visiting ambassadors.Pepin sent letters to Pope Zachary, asking whether the title of king belonged to the one who had exercised the power or the one with the royal lineage.There are conflicting accounts of exactly when Childeric died, with some sources claiming as early as 753, while others state that his death occurred as late as 758.
