Artists and craftsman operated as corporations (guilds) rather than as individual business. Inscriptions mention guilds of weavers, oilmen, artisans, basket and mat makers and fruit sellers. A Saundatti inscription refers to an assemblage of all the people of a district headed by the guilds of the region. Some guilds were considered superior to others, just as some corporations were, and received royal charters determining their powers and privileges. Inscriptions suggest these guilds had their own militia to protect goods in transit and, like village assemblies, they operated banks that lent money to traders and businesses.
