Robert the Strong (c.830 – 2 July 866), also known as Rutpert, also known as Robert IV of Worms, was Margrave in Neustria. His family is named after him and called the Robertians. In 853 he was named missus dominicus by Charles the Bald, King of West Francia. He was the father of two kings of West Francia Odo (or Eudes) and Robert I of France. Robert the Strong was the great-grandfather of Hugh Capet and thus the ancestor of all the Capetians.
