Ramon Berenguer of Aragon
Ramon Berenguer of Aragon (1308 – c. 1366) was the youngest son of James II and Blanche of Anjou. He received the County of Prades and the barony of Entença from his father in 1324. In 1334 his brother Alfonso IV gave him Elche.
In 1341 he exchanged Prades with his brother Peter for the County of Empúries. He first quarrelled with his nephew Peter IV, but Peter's mediation made him one of the king's closest men. He helped put down the Valencian revolts of 1347–1348, went to Pope Innocent VI in 1356 as envoy over Sardinia, and in 1363 defended Valencia against Peter of Castile.
In 1364 he gave Empúries to his son John, who forced him into the Dominican order. He died at Barcelona around 1366.
