Ancient Sanskrit texts, such as Rigveda, Atharvaveda, and Jaiminiya Upanishad Brahmana, mention a legendary king named Ikshvaku (literally, "gourd").

[3] Later texts, such as the Ramayana and the Puranas, connect the dynasty of Ikshvaku's descendants to Ayodhya, the capital of the Kosala Kingdom in northern India.

The 4-line Kesanapalli inscription, dated to his 13th regnal year, and inscribed on the pillar of a Buddhist stupa, names him as the founder of the Ikshvaku dynasty.

Chamtasri, who married Mahatalavara Skandashri of Pukiya family (he is Commander-in-chief and a feudatory), played an important role in the construction of a Buddhist mahachaitya.

[6] The records of the later Ikshvaku kings describe Chamtamula as a great performer of the Vedic sacrifices such as Agnishtoma, Vajapeya and Ashvamedha.

[7][8] These descriptions are corroborated by archaeological discoveries, including those of Chamtamula's Ashvamedha-type coins, a tank used for the Avabhritha ceremony, the kurma-chiti (a tortoise-shaped sacrificial altar), and the skeleton of a horse.

[13] He also married Rudradhara-bhattarika, the daughter of the ruler of Ujjain (Uj(e)nika mahara(ja) balika), possibly the Indo-Scythian Western Kshatrapa king Rudrasena II.

[20] Hariti-putra Virapurushadatta, the son of Ehuvala and queen Kapanashri (Kapanaśrī), bore the titles of an heir apparent: Maharaja Kumara and Mahasenapati.

The Nagarjunakonda inscription, dated to the 11th regnal year, records the erection of a pillar to commemorate the king's mother Vammabhatta.

[21] An inscription dated to the 30th regnal year of the Abhira king Vashishthi-putra Vasusena has been discovered at the ruined Ashtabhuja-svamin temple in Nagarjunakonda.

[23] Assuming 227 CE as the last date of the Satavahana king Puloma IV, and assuming that the Ikshvaku rule began immediately after that, scholar K. Krishna Murthy assigns the following dates to the kings, based on their inscriptions:[10] Historian Upinder Singh estimates the reigns of the Ikshvaku rulers as follows:[24] The Ikshvakus ruled parts of present-day Andhra Pradesh and Telangana.

[9] Chamtashri, the sister of Vasishthiputra Chamtamula, generously donated towards the construction of a mahachaitya ("great chaitya"), which was built during the 6th regnal year of her son-in-law Virapurushadatta, under the supervision of Ananda.

According to the Buddhist tradition, the relics were brought by Mahadeva, a missionary sent by the 3rd century BCE Mauryan empire Ashoka to propagate Buddhism.

[9] Inscriptions dated to the regnal years 6, 10, 14, 15, 18, 19, 20, and 24 of Virapurushadatta's rule record the construction of Buddhist monuments by royal ladies and commoners.

[9] During the reign of Ehuvala Chamtamula, Mahadevi Bhattideva commissioned a monastery for the teachers of the Bhaushrutiya (Bhauśrutīya) Buddhist sect.
