An era called the Simha Samvatsara connected with the name of Jayasimha and beginning with A.D. 1113-1114 (S. 1169-70), occurs in several inscriptions found about Prabhása and South Káthiáváda. This era was probably started in that year in honour of this conquest of Khengár and Sorath. [580] The earliest known mention of the Simha Samvatsara era occurs in a step-well at Mángrol called the Sodhali Váv. The inscription is of the time of Kumárapála and mentions Sahajiga the father of Múlaka the grantor as a member of the bodyguard of the Chálukyas. The inscription states that Sahajiga had several sons able to protect Sauráshtra, one of whom was Somarája who built the temple of Sahajigesvara, in the enclosure of the Somanátha temple at Prabhása; another was Múlaka the náyaka of Suráshtra, who is recorded to have made grants for the worship of the god by establishing cesses in Mangalapura or Mángrol and other places. The inscription is dated A.D. 1146 (Monday the 13th of the dark half of Asvín Vikrama S. 1202 and Simha S. 32). This inscription supports the view that the Simha era was established by Jayasimha, since if the era belonged to some other local chief, no Chálukya viceroy would adopt it. The Simha era appears to have been kept up in Gujarát so long as Anahilapura rule lasted. The well known Verával inscription of the time of Arjunadeva is dated Hijri 662, Vikrama S. 1320, Valabhi S. 945, Simha S. 151, Sunday the 13th of Áshádha Vadi. This inscription shows that the Simha era was in use for a century and a half during the sovereignty of Anahilaváda in Suráshtra.
