After the overthrow of Brihadrata, Pushyamitra Sunga waged a few wars to consolidate his position. Evidence shows that Pushyamitra Sunga defeated the Yavanas. This is confirmed by Patanjali's Mahabashva. And the claim made in the Hathigumpha inscription that Kharavela of Kalinga defeated Pushyamitra Sunga cannot be sustained because Kharavela ruled in the second half of the first century B.C.
