In 1287 King Charles I of Anjou approved the splitting into two entities of the pre-existing Frederick's execution of the Principality and Terra Beneventana: thus the Principatus ultra serras Montorii (beyond the mountains of Montoro, to the north) and the Principatus citra serras Montorii were born ( on this side of the mountains of Montoro., to the south). The border between the two new executions, which later went down in history with the names of Principato Ultra and Principato Citra respectively, was marked by the Picentini mountains. The city of Salerno, already the seat of the previous execution, was reconfirmed as the capital of the Principality of Citra
