Cause → Event → Consequence

Cause

Sustained military conflict between the Greek Duchy of Naples (with its dependencies Sorrento and Amalfi) and the Lombard Principality of Benevento created instability across the Campania region. The Byzantine Empire declined to intervene on behalf of its subjects, leaving the local parties to negotiate a settlement independently.

Event

On 4 July 836, representatives of Naples, Sorrento, and Amalfi signed the Pactum Sicardi with Prince Sicard of Benevento. The multi-clause treaty granted merchant passage through Lombard domains and along key rivers, and abolished the lex naufragii, restoring wrecked cargo to its rightful owners rather than the shoreline landowner.

Consequence

The armistice proved short-lived: war resumed in 837 when Duke Andrew of Naples allied with Saracen forces against Benevento, and in 838 Sicard captured Amalfi by sea. Despite its failure, the treaty reveals competitive interest from both sides in controlling Amalfitan commercial activity and illustrates the persistent fragmentation of southern Italian politics.
