In ancient India, the 'Yaudheyas' were a republican tribe. Yaudheya Gana was an ancient confederation who lived in the area between the Indus River and the Ganga River. They find mention in Paṇini's Ashtadhyayi and Ganapatha. Yaudheyas lay close to the kingdom of the Pandavas. They had taken part in the Kurukshetra War, siding with the Kauravas.
