What is "arjunayanas"

Arjunayana, Arjunavana, Arjunavayana or Arjunayanaka was an ancient republican people located in Punjab or north-eastern Rajasthan. They emerged as a political power during the Shunga period . In the Allahabad Pillar Inscription of Samudragupta , the Arjunayanas figure among the autonomous political communities bordering on the Gupta Empire who accepted the overlordship of Samudragupta. They are also mentioned in Bṛhat Saṃhitā of Varahamihira (6th century CE). According to Dr Buddha Prakash, the Arjunayanas are mentioned as Prajjunakas in Kautiliya's text Arthashastra which also places them in the northern division of India. Vincent Smith locates their republic in Alwar and Bharatpur states now in Rajasthan, a view which has been rejected by R. C. Majumdar.
