Mahavir Swami (Vardhamana) was born in the Śākya/Sākyan lineage, and in Jain scriptures his clan is described as a Kshatriya (warrior) varna. In short:

• Caste lineage: Śākya (not Rajput by the modern Rajput identity)
• Varna: Kshatriya

So, while some modern terms like “Rajput” do not apply to his time and context, Jain texts consistently present his family as part of the Śākya/Kshatriya line. The important point in Jainism is the spiritual path and the teachings he delivered, not his caste.

If you’d like, I can share the traditional verses that mention his lineage and the exact names of his parents.
