Raymond IV of Pallars Jussà

Raymond IV (Catalan: Ramon, Latin: Reimundus, Raimundus) was the Count of Pallars Jussà from 1047 until his death in 1098. He was the son and successor of Raymond III and Ermessenda. His reign was characterised by ceaseless wars and litigations with his cousins Artau I and Artau II of Pallars Sobirà, yet it was transformative in the history of Pallars through the new modes of exercising comital power that Raymond introduced. The viscounties of Pallars Jussà during the time of Raymond IV were Vilamur, Bellera, and Orcau.

There is a rather large and well-preserved series of records for the reign of Raymond IV largely because he pioneered the use of written conventions for the making of agreements in Pallars. In this he was helped along by the same scribe who had at times served his father since 1040 and who had worked at the court of his father-in-law Arnau Mir de Tost for some time, Vidal.
