  	Christening of Siegbert III
  General Information	He was described as the first Merovingian roi fainéant, that is "do-nothing king", in effect the mayor of the palace ruling the kingdom throughout his reign. However he lived a pious Christian life and was later sanctified, being remembered as Saint Sigebert of Austrasia in the Roman Catholic Church and Eastern Orthodox Church. His feast day on 1 February. He is the patron saint of Nancy.  [3]
  Miscellaneous	633 (2 years)  [3]
  A revolt of the nobles forced Dagobert to make the three-year old Sigebert king of Austrasia, similar to how his father Chlotar II had made him king of Austrasia in 623. However, he refused to give the power to Pepin of Landen by making him mayor of the palace for the child-king. Instead he had put Sigebert under the tutelage of Adalgisel as mayor of the palace and the Bishop of Cologne Saint Cunibert as regent, while keeping Pepin in Neustria as hostage.
