Manimangala is the first ever victory for the Pallavas against the Chalukyas and also the first of four successive defeats suffered by Pulakesin II.
Following the accession of Narasimhavarman I in 630, the Pallavas began to grow in strength.
To quell their rise, the Chalukya king Pulakesin II led a southern campaign defeating the Banas on his way to the Pallava kingdom.
[1] Pulakesin proceeded to the town of Manimangala, identified with the present-day Manimangalam, about 20 miles from the Pallava capital Kanchi where he was stopped by a strong Pallava army.
[2] The Kuram plates note that Pulakesin II suffered a defeat and was forced to retreat pursued by the victorious Pallava forces.
