Oswals (Oshwal) are a well-known Jain merchant community. In short:

• Traditional view: Oswals are primarily a Śvetāmbara Jain baniya family network originating from Osian in Rajasthan, with a strong trading-cum-social culture. They are not a single Rajput caste, though origin legends in some sources connect Oswals to Rajput lineages. Different stories exist about their origins, and some historical accounts describe Rajput rulers who adopted Jainism and formed Oswal lineages. In practice today, Oswals are recognized as Jains who belong to various regional Jain traditions (mostly Śvetāmbara), with many gotras used for lineage and exogamy. ( jainknowledge.com)

• Modern view in Jain communities: The important point in Jain Dharma is the spiritual path, not birth-based social hierarchies. Oswals are considered Jains who follow Jain dharma, with sub-division by gotras and regions, rather than a definitive Rajput caste status. Digambar and Śvetāmbara traditions may recount slightly different origin legends, but both recognize Oswals as Jain. ( jainknowledge.com)

• Notable nuance: Some historical sources (and origin legends) claim pure Rajput descent for Oswals, while many contemporary community narratives emphasize their identity as Jain merchants with Osian origins and Śvetāmbara practice. The divergence is primarily in legend and regional tradition, not in core Jain beliefs. ( p-books.com)
