The Navsari branch of the Chalukyas was established by Dharashraya Jayasimhavarman (
IAST: Dharāśraya Jaya-siṃha-varman), who was a son of the
Vatapi Chalukya king
Pulakeshin II, and a younger brother of Pulakeshin's successor
Vikramaditya I. Sometime before 667-670 CE, Vikramaditya appointed Dharashraya as the governor of the north-western Chalukya territories, which included parts of present-day southern
Gujarat, and the
Konkan and
Nashik region of
Maharashtra. Dharashraya is attested by his
Nashik inscription, which is dated to 20 or 21 March 685 (year 436 of the
Kalachuri era). This Sanskrit-language inscription records the grant of the Dhondhaka village in the Nasikya
vishaya (Nashik province) to a
Brahmana named Trivikrama. The Nashik inscription states that Dharashraya defeated and routed the army of a king named Vajjada, between the
Mahi and the
Narmada rivers. Historian
V. V. Mirashi theorizes that Vajrata invaded the
Gurjara kingdom, whose ruler Dadda III was a Chalukya vassal; the Chalukya emperor dispatched Dharashraya to repulse the invader. However, there is no concrete proof to support this theory. Historian Shyam Manohar Mishra theorizes that Vajjada may have been another name for Dadda III. It is possible that this Vajjada is same as the Vajrata, who according to a
Samangad inscription, was defeated by the
Rashtrakuta king
Dantidurga. It is likely that Dharashraya's campaign against Vajjada was ordered by his overlord and nephew
Vinayaditya (the successor of Vikramaditya I), who wanted to expand the Chalukya power in the north.
Shryashraya Shiladitya Dharashraya's eldest son was Shryashraya Shiladitya (IAST: Śrayāśraya Śilādtiya). An inscription of Shryashraya, issued by him as the
crown prince (
yuvaraja), is dated to 23 May 668 (year 420 of the
Kalachuri era). Its
find spot is unknown. It is written in
Sanskrit language using an early form of the
Telugu-Kannada alphabet. It records the grant of Mudgapadra village to migrant
Brahmana cousins Revaditya and Varasyaka by Dharashraya and Shryashraya. The inscription was issued from Navasarika (Navsari) and its text was composed by Dhananjaya. A
Surat inscription of Shryashraya, also in Sanskrit language, is dated to 28 January 671 (Kalachuri year 421). It records the grant of the Asatti village to Bhogikasvamin. Another of his Sanskrit inscriptions, found at Surat, is dated 692-693 (Kalachuri year 443: the date can be read as 2 August 692 CE, assuming that the inscription was issued in the Kalachuri year 443; or as 23 July 693 CE, assuming that it was issued after the expiry of the Kalachuri year 443). The inscription was issued from Kusumeshvara, and records the grant of a field in the Osumbhala village to Matrishvara Dikshita. Shryashraya appears to have died before his father Dharashraya; therefore, Dharashraya was succeeded by his second eldest son Jayashraya Mangalarasa, who was succeeded by Avanijanashraya Pulakeshin, another of Dharashraya's sons. Tribhuvanashraya Nagavardhana, a fourth son of Dharashraya, is attested by an inscription found at Nirpan village of Maharashtra. This inscription records the grant of the Belegrama village to the shrine of the deity Kapaleshvara, but is considered spurious by historians. == Jayashraya Mangalarasa ==
