Sora was founded by the Volsci along the Liri River and was conquered by Rome in 345 BC. In 303 BC it became a Roman municipality.
Here Marcus Regulus was born, who was famous for his involvement in wars against the Carthaginians: winning the Punic War, 264-241 BC, and was able to win again in Africa. The Carthaginians took him prisoner and sent him to Rome in 250 BC to negotiate the peace which never came.
At the fall of the Imperial age Sora suffered looting and devastation by Barbarians but recovered becoming the bishop’s seat and head of Lombard stewardship of the Liri valley, through the princes of Salerno in 847 and Guido da Spoleto in 858.
In the twelfth century it was the scene of the war between the Normans and the Pope and with the victory of the Normans became part of the Kingdom of Sicily, which then passed to the Swabian dynasty and then the Angioini that moved the capital of the Kingdom to Naples.
Sora became the seat of a county, the County of Sora, that in 1443 became the Duchy, a sort of buffer state between the Papal State and the Kingdom of Naples. In this period it was led by the families of Tomacelli (1399), the Cantelmo (1439), the Della Rovere (1475) and Boncompagni. In 1796, King Ferdinand IV of Naples suppressed the Duchy of Sora and bought the dukedom from Antonio Boncompagni.
