Ramon Berenguer III and Douce of Provence Unite Catalonia and Provence
On February 3, 1112, Count Ramon Berenguer III of Barcelona married Douce I, heiress of Provence, in a union that reshaped the politics of the western Mediterranean. According to medieval charters, this alliance effectively brought Provence under the influence of the House of Barcelona. The marriage strengthened trade routes across the Pyrenees and along the Mediterranean coast. It laid foundations for a cross-border power base that later influenced the Crown of Aragon’s rise as a major maritime force.
