The House of Welf (also Guelf or Guelph) is a European dynasty that has included many German and British monarchs from the 11th century to 20th century and Emperor Ivan VI of Russia in the 18th century. The originally Franconian family from the Meuse-Moselle area was closely related to the imperial family of the Carolingians.
