Ramon Berenguer IV, Count of Provence

Ramon Berenguer IV or V was a member of the House of Barcelona who ruled as count of Provence and Forcalquier. He was the first count of Provence to live in the county in more than one hundred years. During the minority of a previous count in 1144–1161, the regency was exercised by Ramon Berenguer IV de Barcelona, who is sometimes counted among the counts of Provence, which has led to varied numbering of the counts of Provence named Ramon Berenguer. This Ramon Berenguer was the fourth of his name to be a reigning count of Provence.
