Where did the jain religion start from and in which year

Jainism is believed to have started in the ancient Ganga valley, a region that was culturally and spiritually fertile long before the arrival of the Aryans and their priestly religions. The origins of Jainism are traced to a pre-historic era, emphasizing a tradition of asceticism, morality, and austerity that predates many other Indian religious movements. This antiquity places Jainism among the oldest known religious philosophies, particularly linked to the Dravidian cultural period before Aryan influence.
