Vincenzo Gioberti's Del primato morale e civile degli italiani (1843) has been acknowledged as a major influence on moderate liberal thinking in the Risorgimento. Yet historians and political theorists have tended to dismiss the text as ponderous, unreadable or worse. The concern of this paper is to present what was once seen as a canonical text in terms that might make its initial appeal intelligible. Gioberti's text is set in the context of theological reappraisals within the Catholic tradition sparked by the rise of the national idea. The Primato managed to bring together currents of thought which are often regarded as antithetical. Catholic universalism was used to buttress and legitimize a specific view of the Italian nation. Gioberti's synthesis was to have a lasting impact on Italian liberalism, fostering a regard for established traditions rather than abstract rights. It also served to isolate revolutionaries and reactionaries in a dramatic and decisive decade for political debate in Italy.
