Buddhism was just one of the new doctrines which appeared in the mid-first millennium, however. Two other famous groups of many which appeared were the jains, which are still significant in part of western and southern India, and the Ajivikas. These, like Buddhism, appealed especially to unban audiences. Buddhism was popular among some groups of rich grhapati householders because it supported the investment of economic surplus. Thus grhapati patronage went to members of the Buddhism sangha, to Buddhism monastic organization showed the development of new relationships in north India urban society which went beyond kinship, new types of social and political connection which could serve as part of the base upon which a new political order could emerge. In fact, Thapar argues that, some rudimentary state system was required to establish and maintain a sangha or monastery in an area. The Buddhists, in other words, would support a stronger monarchical structure to protect their religions doctrine; this was also a way of protecting their financial interests.
