Livorno was, in the sixteenth century, barely a town. The Medici had inherited a swampy fishing village with a harbor and an ambition attached to it: Tuscany needed a port that could compete with Venice and Genoa, and it had nothing of the kind.
Grand Duke Ferdinando I de' Medici solved the problem with a document. In 1591, and again in a revised version promulgated on 10 June 1593, he issued the letters patent that history remembers as the
Livornine a public invitation to merchants of every nation to come to Pisa and Livorno and trade.
The text is formally addressed to merchants "of any nation": Levantine, Ponentine, Spanish, Portuguese, Greek, German, Italian, Jewish, Turkish, Moorish, Armenian, Persian. In practice, everyone understood who was actually being invited: Portuguese and Spanish
conversos, New Christians living under the shadow of the Inquisition, and Sephardic Jews from the Ottoman lands.
What Ferdinando offered them was extraordinary for its century:
- The right to settle with their families, come and go freely, and trade without impediment
- Freedom to practice Judaism openly, including for New Christians who had been baptized under duress
- No ghetto, no compulsory badge, no restriction on where in the city they could live or trade
- Tax exemptions and immunity from prosecution for religious offenses committed abroad
- The right to own property, employ Christians, and educate their children
- Communal self-government under their own elected leadership
The charter was granted for twenty-five years, renewable and it was renewed, again and again, remaining in force in substance until Italian unification. Livorno became a city in 1606 and a free port in 1675.
