The
guilds, medieval institutions that organized every aspect of a city's economic life, formed a social network that complemented and in part compensated for family ties, although in Florence the welfare side of the guilds' activities was less than in many cities. The first of the guilds of Florence of which there is notice is the
Arte di Calimala, the cloth-merchants' guild, mentioned in a document of about 1150. By 1193 there existed seven such corporate bodies, which each elected a council whose members bore the Roman-sounding designation
consoli. A single
capo was elected to manage all the business of the guild. Entrance to the
Arti was highly structured from the first records; it was necessary to be the legitimate son of a member, to give proofs of competence in the craft involved, and to pay an entrance tax. Masters of the guilds, who possessed the means of production, took on
apprentices and
garzoni, the "boys" or journeymen who might work through a long career without ever becoming a master. Each of the
Arti was ruled according to its statutes, which had the force of law, and might pass judgement in controversies among its members and with their workers. In the fourteenth century the guilds established the market tribunal called the
Mercatanzia to hear causes that involved more than one of the
Arti. The Palazzo del Tribunale della Mercatanzia (
illustration, right) still occupies a prominent place in the
piazza della Signoria, befitting the controlling role of the
Arti in governing Florence. As elsewhere, the guilds of Florence protected its members from competition within the city by strangers and Florentine outsiders, guaranteed the quality of work through strict supervision of the workshops (
botteghe), stipulated work hours, established markets and feast days, and provided public services to its members, and their wives, widows and children. During the fifteenth century city watchmen were organized by the
Arti to protect closed workshops and warehouses. From the beginning, not all
Arti were equal: to the original seven
Arti Maggiori were added fourteen
Arti Minori as the guild system spread. ==Role in Florence==
