The 1164 CE Delhi-Shivalik pillar inscription states that Vigraharaja conquered the region between the
Himalayas and the
Vindhyas. The Himalayas and the Vindhyas form the traditional boundary of
Aryavarta (the land of ancient
Aryans), and Vigraharaja claimed to have restored the rule of Aryans in this land. While his claim of having conquered the entire land between these two mountains is an exaggeration, it is not completely baseless. His Delhi-Shivalik pillar inscription was found at Topra village in Haryana, near the
Shivalik Hills. This indicates that Vigraharaja captured territories to the north of Delhi, up to the Himalayan foothills. Raviprabha's
Dharmaghosha-Suri-Stuti states that the ruler of
Malwa and Arisiha (possibly Arisimha of
Mewar) assisted him in hoisting a flag at the Rajavihara Jain temple in Ajmer. The ruler of Malwa here probably refers to a claimant to the
Paramara kingdom, which had been captured by the
Chaulukyas during this period. Assuming that the claimant to the Malwa throne had accepted Vigraharaja's suzerainty, it appears that Vigraharaja's influence extended up to the Vindhyas, at least in name. His kingdom included the present-day Rajasthan, Haryana, and Delhi. It probably also included a part of
Punjab (to the south-east of
Sutlej River) and a portion of the northern Gangetic plain (to the west of Yamuna). The play
Lalita-Vigraharaja-Nataka, composed by Vigraharaja's court poet, claims that his army included 1 million men; 100,000 horses; and 1,000 elephants.
Chaulukyas of Gujarat , 12th century Vigraharaja's father
Arnoraja had suffered a humiliating defeat at the hands of
Kumarapala, the
Chaulukya king of Gujarat. Vigraharaja launched several expeditions against the Chaulukyas to avenge his father's defeat. According to the
Bijolia rock inscription, he killed one Sajjana. The inscription describes Sajjana as "the most wicked person of the land", who was sent to the abode of
Yama (the god of death) by Vigraharaja. Historian
Dasharatha Sharma identified Sajjana with Kumarapala's governor (
daṇḍāhiśa) of
Chittor. According to the Jain author Somatilaka Suri, Vigraharaja's army captured Sajjana's
elephant force. While Vigraharaja was busy fighting at Chittor, Kumarapala tried to create a diversion by besieging
Nagor, but lifted the siege after learning about Vigraharaja's victory at Chittor. A Chahamana
prashasti (
eulogy) boasts that Vigraharaja reduced Kumarapala to a
karavalapala (probably the designation of a subordinate officer). This is obviously an exaggeration, but it does appear that Vigraharaja conquered some of Kumarapala's territories. The earliest Chahamana inscriptions from the
Bijolia-
Jahazpur-
Mandalgarh area are dated to Vigraharaja's reign.
Chahamanas of Naddula in
Bisalpur was constructed by Vigraharaja IV. Vigraharaja subdued the
Chahamanas of Naddula, who had branched off from the Shakambhari Chahamana dynasty, and were feudatories of the Chaulukya king Kumarapala. The Bijolia inscription boasts that he turned Javalipura (modern
Jalore) into "Jvalapura" (city of flames); reduced Pallika (modern
Pali) to a
palli (a hamlet); and made Naddula (modern
Nadol) a
nadvala (a cane-stick or a marsh of reeds). The Naddula ruler subdued by him was probably
Alhanadeva. Vigraharaja also defeated one Kuntapala, who can be identified with a Naddula Chahamana subordinate of Kumarapala.
Tomaras of Delhi The
Bijolia rock inscription states that Vigraharaja conquered Ashika (identified with
Hansi) and
Delhi. The Chahamanas had been involved in conflicts with the
Tomaras of Delhi since the time of his ancestor
Chandanaraja. Vigraharaja put an end to this long conflict by decisively defeating the Tomaras, who had grown weak under attacks from the Chahamanas, the
Gahadavalas and the Muslims. The Tomaras continued to rule for a few more decades, but as vassals of the Chahamanas. An old
bahi (manuscript) states that Visaladeva i.e. Vigraharaja captured Delhi from Tamvars (
Tomaras) in the year 1152 CE (1209
VS). According to historian R. B. Singh,
Hansi might have been under Muslim control by this time. On the other hand, Dasharatha Sharma theorizes that the Tomaras had recaptured Hansi from
Ghaznavids by this time, and Vigraharaja captured it from the Tomaras. The legendary epic poem
Prithviraj Raso states that the later Chahamana king
Prithviraja III married the daughter of the Tomara king Anangapala, and was bequeathed Delhi by the Tomara king. Historian R. B. Singh speculates that it was actually Vigraharaja who married the daughter of the Tomara king. According to Singh, Desaladevi, who has been mentioned in the play
Lalita-Vigraharaja-Nataka as Vigraharaja's lover, might have been the daughter of a Tomara king named Vasantapala.
War against the Turushkas Several sources indicate that Vigraharaja achieved military successes against the
Turushkas, the Muslim Turkic invaders. The Delhi-Shivalik pillar inscription boasts that he destroyed the
mlechchhas (foreigners), and once again made
Aryavarta ("the land of
Aryans") what its name signifies. The
Prabandha-Kosha describes him as "the conqueror of Muslims". The Muslim invaders forced to retreat by him were probably the
Ghaznavid rulers
Bahram Shah and
Khusrau Shah. The plot of
Lalita Vigraharaja Nataka involves Vigraharaja's preparations against a Turushka ruler named Hammira (
Emir). In the story, his minister Shridhara tells him not to risk a battle with a powerful adversary. Nevertheless, Vigraharaja is determined to fight the Turushka king. He sends a message to his lover Desaladevi, informing her that the upcoming battle would soon give him an opportunity to meet her. The play describes Desaladevi as the daughter of prince Vasantapala of Indrapura. The play is available only in fragments, so the details of the ensuing battle are not known. Historian
Dasharatha Sharma identified Hammira with Khusrau Shah, and assumed that Vigraharaja repulsed his invasion. Historian R. B. Singh, on the other hand, theorizes that no actual battle took place between Vigraharaja and Hammira. According to Singh's theory, the "Hammira" on the play might have been Bahram Shah, who fled to India after the
Ghurids defeated him at the
Battle of Ghazni (1151). Bahram Shah invaded the
Tomara territory of
Delhi after coming to India. Vasantapala might have been a Tomara ruler, possibly Anangapala. Indrapura may refer to Indraprastha, that is, Delhi. Vigraharaja probably decided to send an army in support of the Tomara king. But before an actual battle could take place, Bahram Shah returned to Ghazna as the Ghurids had departed from that city.
Other conquests According to the Bijolia inscription, Vigraharaja also defeated the
Bhadanakas. The
Prithviraja Vijaya claims that he conquered several hill forts. == Cultural activities ==
