Nanda Dynasty Overthrow and Sectarian Roles

The question asks to identify a contemporary religious sect associated with the overthrow of the Nanda dynasty in ancient India.

Role of the Jaina Sect

Historical traditions and scholarly interpretations suggest a connection between the Jaina sect and the events leading to the fall of the Nanda empire. Key figures involved in challenging the Nandas, particularly the Brahmin Chanakya (Kautilya), are sometimes linked to Jainism or influenced by its philosophical tenets. The rise of alternative religious and philosophical movements like Jainism and Buddhism challenged the existing Brahmanical orthodoxy often associated with the Nanda rule, potentially contributing to the socio-political climate that facilitated their downfall.

Analysis of Options

• Ajivaka: While contemporary, the Ajivaka sect, known for its fatalism, is not prominently linked to the political overthrow of the Nandas.
• Bauddha: Buddhism was also a contemporary sect and grew significantly during the Mauryan period, but the specific role in the *overthrow* is less emphasized compared to Jainism in certain traditions.
• Charavaka: This materialistic and atheistic school of thought is generally not considered to have played a direct role in the political upheaval involving dynastic changes.
• Jaina: This sect holds a more frequently cited association, through figures like Chanakya or the general challenge it posed to established norms, in the context of the Nanda dynasty's end.

Conclusion

Based on historical associations and traditions concerning the intellectual and religious climate of the time, the Jaina sect is considered to have played a role in the events surrounding the overthrow of the Nanda dynasty.
