Life [edit]
Berthold IV succeeded his father, Conrad I, in 1152 as Duke of Zähringen. Berthold also claimed the title of "Duke of Burgundy". However, Emperor Frederick Barbarossa married Beatrice, the daughter of the last Count of Burgundy of the House of Ivrea. This interfered with Berthold's claims and Berthold was given the title of Rector of Burgundy and was made overlord over Geneva, Lausanna and Sion.
The rivalry with Duke Frederick IV of neighbouring Swabia caused him to fight on the side of Welf VI in the Feud of Tübingen (1164-1166). In 1173, he became overlord of Zurich.
An entry in the necrology of the Abbey of Saint Peter in the Black Forest reads Berchtoldus 4. dux de Zaeringen, offcium cum 5 candelis. Depositio Iohannis Tüfer abbatis: "Berthold IV, Duke of Zähringen donated 5 candles for the memory of John the Baptist".[1]

Berthold IV was married to Heilwig of Frohburg, with whom he had three children:
- Berthold V, the last Duke of Zähringen. After his death, the counts of Kyburg and Urach inherited the Zähringen possessions
- Agnes, married to Count Egino IV of Urach — According to the necrology of Tennenbach Abbey, she was the daughter of Berthold V[2]
