When did digambar start and shwetambar start

The Digambar and Śvetāmbara traditions did not begin as two separate religions. In Jain history, they are understood as two traditions that gradually emerged after the original Jain sangha.

A commonly accepted Jain historical understanding is:

• Division began around the 3rd century BCE, after the famine in North India and the migration led by Acharya Bhadrabahu.
• The Digambar tradition is associated with the path that preserved the ideal of complete non-possession and the ascetic practice of remaining without clothes.
• The Śvetāmbara tradition became distinct later as the community in western India developed its own monastic practices and scriptural preservation.

So, in simple terms:

• Root split: around 3rd century BCE
• Distinct traditions became established over the following centuries

If you want, I can also explain why Digambar and Śvetāmbara differ in simple Jain terms.
