How were craft guilds financed

An association of persons with a particular skill or trade. For example, the electricians in an area may form a guild for mutual support, to route business to each other, or for other reasons. A guild contrasts with a union primarily because it includes both employers and employees; it is based on trade, rather than class. Guilds were most common in medieval Europe, but still exist and have a great deal of sway in some industries, notably filmmaking. Bar associations of lawyers and realtor groups may also be considered guilds.
