An ancient Indian military ganasangha (warrior republic) of the eastern Sapta Sindhu (roughly modern Haryana, extending into Punjab and northern Rajasthan), first attested in Panini (c. 500 BCE) and known through the 2nd century CE chiefly from its own coinage and Rudradaman I's Junagadh rock inscription (c. 150 CE), which calls them 'heroes among all Kshatriyas' who 'were loath to submit.'
Annexed by the Kushan Empire under Kanishka in the 2nd century CE, then rebelled: c. 180 CE the Yaudheyas, with the Arjunayanas and Kunindas, drove the Kushans out of the eastern Punjab (commemorated on their own coinage, which drops Kushan Kharosthi script for Brahmi). The republic persisted, submitting peacefully to the Gupta Empire under Samudragupta (per the Allahabad Pillar inscription) before gradually dissolving in the 4th century CE.
