The Audumbaras were an ancient tribal republican state in the Punjab/Himachal region (around the Ravi and Beas valleys) during the 1st century BCE to 1st century CE. Their coins are known for featuring various symbols, including the trident (Trisula), often alongside other motifs like an axe, tree-in- railing, stupa, or animals like deer. The trident is a particularly prominent symbol on their coinage.
