Discusses Livorno’s evolving trade with the US in West Indian imports and fish and how the Napoleonic Wars and First Barbary War impacted trade. Also discusses the American consul’s role in mitigating conflict within the American communtiy and between Americans and Italians.

The Congress of Vienna in 1814–1815 delineated territorial settlements, coronated several newly independent monarchs and resulted in an official declaration on the abolition of the slave trade, but it did not treat the issue of piracy. This paradox is the key concern of this chapter. Vienna’s Final Acts were the end product of these talks, and though they did not mention ‘Barbary piracy’, their conclusion would nevertheless have a great impact on the international treatment of this newly perceived threat to security. The years 1814–1815 were an important turning point because they initiated a period of transition. The congress created an international context in which North African corsairing could be reconceived as a threat to security. This new perception of threat hinged upon misconceptions of the supposed fanaticism and irrationality that allegedly characterised North African privateering. It also disregarded the long history of diplomatic and commercial contact between both sides of the Mediterranean Sea.
