TELANGANA RULERS STARTED SHALIVAHANA SAKA

Eventually Gautamiputra (Sri Yagna) Sātakarni (also known as Shalivahan) (78-106 CE) defeated the Western Satrap ruler Nahapana, restoring the prestige of his dynasty by reconquering a large part of the former dominions of the Sātavāhanas. He was an ardent supporter of Hinduism.

According to the Nasik inscription made by his mother Gautami Balasri, he is the one who crushed down the pride and conceit of the Kshatriyas (the native Indian princes, the Rajputs of Rajputana, Gujarat and Central India); who destroyed the Shakas (Western Kshatrapas), Yavanas (Indo-Greeks) and Pahlavas (Indo-Parthians) etc,who rooted the Khakharata family (The Kshaharata family of Nahapana); who restored the glory of the Satavahana race

Gautamiputra Satakarni may also have defeated Shaka king Vikramaditya in 78 AD and started the calendar known as Shalivahana era or Shaka era, which is followed by the Marathi and Telugu people and is the Indian National Calendar.

Gautamiputra Sātakarni's son, Vashishtiputra Pulumāyi (106-130 CE), succeeded him. Gautamiputra was the first Sātavāhana king to issue the portrait-type coinage, in a style derived from the Western Satraps
