Any religion in history has spread mostly under following condition 1. When people are not following any distinct religion or 2. When people are forced to follow a religion If a community is not following any religion, than a spiritual leader who guides them initiates a religion.Eg.
Muhammad , Jesus etc. If people are already following a religion, than it is difficult for them to migrate to another religion When a new ruler captured a state, people there were usually forced to follow ruler's religion. This is how people change their religion At the time when Jainism started, many religion were already flourished.So people were reluctant to leave their religion.

This is the region why there are few followers of Jainism.
