In Ancient India, a shreni (Sanskrit: श्रेणि, romanized: śreṇi or श्रेणी śreṇī, Prakrit: seni)[1] was an association of traders, merchants, and artisans.
Over a period of time, some shrenis became very wealthy with surplus resources, and acted as custodians and bankers of religious and other endowments.
One of the widely referred shreni was of ivory carvers of Vidisha (in the modern Indian state of Madhya Pradesh).
This shreni is accredited with sponsoring and financially supporting the construction of the southern gateway of the stupa at Sanchi, which is currently a World Heritage Site.
The Manusmriti stated "A king must inquire into the law of groups (jāti), of districts (ganapada), of guilds (shreni), and of families (kula).
