Pactum Sicardi

The Pactum Sicardi was a treaty signed on 4 July 836 between the Greek Duchy of Naples, including its satellite city-states of Sorrento and Amalfi, represented by Bishop John IV and Duke Andrew II, and the Lombard Prince of Benevento, Sicard.

The treaty was an armistice ending a war between the Greek states and Benevento, during which the Byzantine Empire had not intervened on behalf of its subjects.

He made navigation up the rivers Patria, Volturno, and Minturno open to merchants, responsales (envoys), and milities (soldiers).

Sicard did not give up his powers of enforcement over either the illegal slave trade (in Lombards) or the trafficking of stolen merchandise.
