Ramon Berenguer III of Provence

Ramon Berenguer III of Provence (c. 1158–1181), born Peter, was the third son of Ramon Berenguer IV of Barcelona and Petronilla of Aragon. He first held Cerdanya, but passed it to his younger brother Sancho in 1168, and in 1173 their elder brother King Alfonso II granted him Provence.

In 1176 he helped Sancho take Nice, then campaigned in Languedoc and against Toulouse. In 1181 he was assassinated near Montpellier, and Provence passed to Sancho.
