Fulk Bertrand of Provence

Fulk Bertrand I was the joint Count of Provence with his elder brother William IV from 1018 and with his younger brother Geoffrey I from at least 1032 if not earlier. After William's death, Fulk assumed the title of margrave, indicating headship of the dynasty. They were the sons of William II, count of Provence. Provence was during this time part of the Kingdom of Arles, and in 1033 also became part of the Holy Roman Empire.
