Raimond-Berenger IV of Barcelona

Raimond-Berenger IV of Barcelona , known as the Saint , or as a Catalan Ramon Berenguer IV (born in 1113 - died the August 6th 1162 with Borgo San Dalmazzo, Italy) was count de Barcelone. He is especially known to see be the craftsman of the union of the Aragon and the Catalogne.

His/her parents were Raimond-Berenger III of Barcelona and Douce of Gévaudan. He inherited the Comté it Barcelona the July 19th 1131. The August 11th 1137, with Huesca, it was promised with the infante Pétronille d' Aragon, 3 years old at the time. The father of this one, Ramiro II of Aragon, which had required the assistance of the county of Barcelon against Alphonse VII of Castille, abdicated the November 13rd same year, bequeathing his kingdom to Pétronille and her husband. Raimond-Berenger IV controlled Aragon since then, without however being made some crown king; he preferred to carry the title of Count de Barcelone and prince of the Royaume of Aragon. He was the last Catalan monarch to use initially the title of count de Barcelone; starting from his/her son Alphonse II of Aragon the counts of Barcelona used initially the title of kings d' Aragon.

The treaty between Raimond-Berenger IV and his father-in-law stipulated that its descendants would control the two kingdoms jointly. Even if Pétronille died before the marriage is consumed, the count of Barcelona would inherit the crown of Aragon. The two kingdoms should preserve their own laws, their institutions and their autonomy, and remain distinct on the plan from the laws but plain under the reign of only one dynasty.

The historians regard this arrangement as one of the political masterpieces of the Hispanic Middle Ages. The two kingdoms gained there in force and safety. On another side, the formation of a new political entity at the time when the Portugal made secession of the Castille contributed to balance between the Christian kingdoms of the peninsula.

He was the founder of the town of Barcelonnette, in the Vallée of Ubaye.
