Like much of the rest of Novgorod's medieval history, the precise composition of these trade or crafts organizations is uncertain and they ought not to be confused with the much more organized guilds (or later unions) of Western Europe. It is quite possible that the "ends" and "streets" were simply neighborhood administrative groups rather than guilds or "unions". Street organizations were known to build churches in their neighborhoods and to have buried the dead of their neighborhoods during outbreaks of the plague, but beyond that their activities are uncertain. As for Ivan's Hundred, its exact nature is not known. It was organized around the Church of St. John the Forerunner on the Opoki, just north of the marketplace, and each member had to pay an entrance fee of a bolt of Ypres cloth (from Flanders) to the archbishop. The tysyatsky arbitrated disputes between the members. Other than that, the activities of Ivan's Hundred is unknown.
