Tommaso Mocenigo is the 64ème Doge de Venise elected in 1413.

In his quantified speech pronounced in 1423 for évincer of the succession its rival Francesco Foscari, Tommaso Mocenigo gives us indications on the economic situation of the Republic: the trade represents an annual value of 10 million Ducat S with export and as much with the importation. The city, a long time without back-country, imports initially foodstuffs (cereals, meat, oil and wine) which are the subject of an extremely rigorous monopoly of the State. The State behaves like a gigantic company of navigation: every year, it charters, under the authority from the Senate, fifteen to twenty vessels from 300 to 500 barrels, sailing always grouped by two or four, towards the East, Egypt, North Africa, and more and more the English and Flemish ports (Bruges). Little by little the navy improves and one sees appearing the imposing one galée ( will galera di mercato ) and the hull with square aerofoil, the use of the Boussole. Rare goods enrich the city: spices (pepper), silk and cotton of the East or Egypt, sweetens, metals of Saxony and Thuringe. At the sides of the large vessel circulate more than 3000 smaller ships and 45 galères as well as a flotilla of barges and boats conveying the cargoes of the large boats to the port: the principle of “Dominant” implies that all the goods must forward by the port of Venice, but all the boats cannot enter there.

The sea makes live at least 36.000 sailors, those of the State and the private companies, which function according to the system of the colleganza or contract of association: a associate brings two thirds of the capital, the other the remaining third and its activity, the benefit are also distributed. Perhaps naval constructions employ 16.000 workmen (including 3000 carpenters and 3000 caulkers), divided into sixteen corporations or arti. A galère can be built in only one day. The arsenal, key of the Venetian power according to Dante, is by far the greatest hard concentration of all preindustrial Europe.

At XIVe and 15th century, the textile occupies 16.000 workmen (silk of Egypt or China, cotton of Syria and wool). Leather, wood, goldsmithery, the metallurgy, the work of the ivory, glass (Murano), are important activities.
