Around 200 BC, Satavahana dynasty became powerful in Western India. Gautamiputra Shri Satakarni was the most significant ruler of this dynasty. We know about him from an inscription by his mother, Gautarmi Balashri.
He, alongwith other rulers of his dynasty, came to be known as Lords of the Dakshinapatha.
Dakshinapatha literally refers to the route leading to the South and entire South region was known by this name.
Gautamiputra sent his army to the Eastern, Western and Southern coast.
