Jains did not “split” in one day by a fight; the division into Digambar and Shvetambar formed slowly over a long time due to history, geography, and differences in practice.

Here is a simple, traditional explanation:

1. Time after Bhagwan Mahavir

- After Mahavir Swami’s nirvana, Jain sangh spread in many regions. - Acharyas and sadhus were travelling, teaching, and trying to preserve the agams (scriptures).

1. Period of famine and separation

- Ancient Jain tradition says a long famine came in Magadh (around the time of Acharya Bhadrabahu). - To protect the sangh, one group of sadhus went towards South India with Acharya Bhadrabahu. - Another group stayed in North India under Acharya Sthulabhadra. - For many years these two groups lived separately, in different climates and social conditions.

1. Differences slowly appear

Because of this long separation, some differences in practice and understanding slowly developed:

- Clothing of monks - In the southern group, very strict aparigraha (non‑possessiveness) and complete nudity of munis was kept – this line later came to be known as Digambar (“sky‑clad”). - In the northern group, due to local conditions and interpretation of rules, monks started using simple white clothes while still practising renunciation – this line became Shvetambar (“white‑clad”).

- Scriptures (Agam) - When monks later met again and tried to compile/scripturally fix the agams, there were differences: - Shvetambar tradition accepts a collection of Agams as preserved in councils. - Digambar tradition holds that the original Agams were lost and does not accept the Shvetambar canon as fully authentic, following other texts instead (like Shatkhandagam, Kasayapahud, etc.).

- Some doctrinal points Over time, different views formed on a few issues, for example: - Can a true muni keep clothes or not? - Can a woman attain moksha in the present female body or must she take birth as a man? - Small differences in how Tirthankar idols should be shown (naked / clothed, eyes open / downcast).

1. What is important to remember

- Both Digambar and Shvetambar: - Accept the same Tirthankars, including Bhagwan Mahavir. - Accept the same basic tattvas: jiva–ajiva, karma theory, moksha, ahimsa, aparigraha, anekantvad, etc. - Aim for the same goal – moksha through right faith, right knowledge and right conduct. - The differences are mainly in monk discipline, scriptures accepted, and some details of doctrine and idol‑worship, not in the basic principles of Jain Dharma.

So, Jains became Digambar and Shvetambar mainly due to historical separation and different ways of practising the same Jain principles over many centuries, not because Jain dharma itself changed.
