The tribes underwent a change of lifestyle after finding an economic niche as pastoralists, but also adopted habitation patterns from the depopulated Hungarian villages where they had been originally settled. Though enjoying some fiscal privileges, the Cumans and Jazyges were ordered by King Sigismund to pay an annual census tax—a measure which may indicate that they were no longer relevant as soldiers. In the 15th century, both groups were urbanized enough to be organized into "seats", "universities", and "captaincies", all of which were under a Palatine of the Kingdom. The first seat was "Szentelt-szék", mentioned in 1424 and located outside Kunság, among the Kór. Another one was organized in 1440 for the Olás tribe of Greater Cumania, at Kolbaz.
