title: Frederick V, Duke of Swabia
text: # Frederick V, Duke of Swabia
  
  Frederick V of Hohenstaufen (Pavia, 16 July 1164 – c. 1170) was Duke of Swabia from 1167 to his death. He was the eldest son of Frederick I Barbarossa and Beatrice I, Countess of Burgundy.
  
  ## Life
  
  In April 1165 Frederick was betrothed to Eleanor, daughter of King Henry II of England and his wife Eleanor of Aquitaine. The marriage, however, never took place due to Frederick´s early death.
  
  In August 1167, Duke Frederick IV of Swabia died on an Italian campaign. As the only living son of King Conrad III of Germany (uncle and predecessor of Barbarossa) and without any offspring from his short-lived marriage with Gertrude of Bavaria, with him his line died out and his domains were devolved to Barbarossa. The Emperor appointed three-years-old Frederick as the new Duke of Swabia, becoming in Frederick V.
  
  In June 1169 during the Hoftag in Bamberg, Frederick V's younger brother Henry was elected King of the Romans and crowned on 15 August at Aachen Cathedral. It can be assumed that Frederick V was bypassed from the royal succession because he had a weak constitution since birth and wasn't expected to survive infancy.
  
  Two medieval sources confirms that Frederick V was still alive when his brother was elected King of the Romans. Since his fiancée Eleanor was married to King Alfonso VIII of Castile in 1170, is assumed that he died in mid-1169 or early 1170.
  
  Frederick V was buried in Lorch Abbey, the royal necropolis of the Staufen dynasty, donated by his great-grandfather Frederick I, Duke of Swabia. In 1475 Abbot Nikolaus Schenk von Arberg had the remains of all the members of the Staufen dynasty buried in Lorch transferred to a late Gothic tombstone, which is now in the central nave of Lorch Abbey.
  
  After his death, Frederick V's name passed to Barbarossa's third son, who was originally called Conrad, who succeeded his late brother as Frederick VI, Duke of Swabia; in this way, the familiar and leading Staufen name Frederick must be preserved. Since Otto, the next son of Barbarossa born after Conrad/Frederick VI, was probably born during June–July 1170, Frederick V must have died some time before, otherwise the rather unusual renaming of Conrad would have been without purpose, because the Emperor could simply have called the next son Frederick (instead of Otto).
