After Mangalesha's death, Pulakeshin appears to have faced opposition from multiple rivals, including those who were loyal to Mangalesha and those who wanted to take advantage of the turmoil resulting from the Chalukya war of succession. The
Aihole inscription declares that "the whole world was enveloped in the darkness that was the enemies". Pulakeshin subjugated these enemies, and established the Chalukyas as the dominant power in the Indian peninsula.
Appayika and Govinda The Aihole inscription suggests that two rulers named Appayika and Govinda rebelled against Pulakeshin. The identity of these rulers is uncertain, but they are said to have approached the core Chalukya territory from the north of the Bhimarathi (modern
Bhima) river in present-day
Maharashtra. According to historian
K. A. Nilakanta Sastri, the way they are mentioned in the inscription suggests that they were military adventurers and not from a royal background. However, according to historian Durga Prasad Dikshit, their names suggest that they may have belonged to a Rashtrakuta branch, which was distinct from the imperial
Rashtrakutas of Manyakheta. This branch may have become subordinate to the Chalukyas after facing invasions from the
Nala and Mauryas of Konkan, and later rebelled taking advantage of the conflict between Pulakeshin and Mangalesha. According to the Aihole inscription, Pulakeshin adopted the policy of
bheda (divide and conquer), and bestowed favours upon Govinda while alienating Appayika. Govinda became his ally, and Appayika was defeated.
Recapture of Banavasi Pulakeshin's predecessors had subjugated the
Kadambas of
Banavasi, but the Kadambas no longer recognized the Chalukya suzerainty during his reign. Pulakeshin marched against them, and besieged their capital of Banavasi. The Aihole inscription suggests that the Kadambas put up a strong resistance, but were ultimately defeated. The Kadamba ruler at this time was probably Bhogivarman. Pulakeshin ended the Kadamba dynasty, and annexed their territory to his empire. He divided this territory among his vassals: the major part of the Kadamba kingdom was granted to the
Alupas under the name kadamba-mandala; the Nagarakhanda division of Banavasi was given to the Sendrakas.
Alupas According to the Aihole inscription, Pulakeshin subjugated the
Alupas, who had earlier served as Kadamba vassals. However, according to the Chalukya inscriptions, the Alupas had already been subjugated by Pulakeshin's predecessors. Therefore, it appears that the Aihole inscription simply refers to Pulakeshin reaffirming the Chalukya suzerainty over the Alupas. Another possibility is that the Alupas had not been completely subdued by the Pulakeshin's predecessors. The location of the core Alupa territory during Pulakeshin's period is not certain. Alupas are known to have been ruling in the Dakshina Kannada region of Karnataka for several centuries, but some scholars believe that their capital was located at Humcha in the Shimoga district. After subjugating the Kadambas, Pulakeshin assigned a major part of the former Kadamba territory to his Alupa vassal, who according to historian Moraes, may have been Kundavarammarasa. If "Aluka" is considered a variant of "Alupa", the Marutura inscription suggests that the Alupa vassals of Pulakeshin also ruled over the Guntur district in present-day Andhra Pradesh. According to this inscription, the Aluka ruler Gunasagara, who was a Chalukya vassal, was appointed to govern this region. The 692 CE Sorab inscription describes Gunasagara's son Chitra-vahana as an "Alupa", which suggests that "Aluka" is a variant of "Alupa".
Gangas of Talakad The Aihole inscription credits Pulakeshin with subjugating the
Gangas of
Talakad, who had matrimonial ties with the Kadambas. The Mahakuta pillar inscription of his predecessor Mangalesha states his father Kirttivarman also subjugated the Gangas. It is possible that the Gangas accepted the Chalukya suzerainty during Kirttivarman's reign, but subsequently gave up this allegiance taking advantage of the war of succession between Mangalesha and Pulakeshin. After Pulakeshin's victory over the Kadambas, the Gangas again accepted the Chalukya suzerainty, possibly without any military conflict. The Ganga ruler
Durvinita married his daughter to Pulakeshin; she was the mother of Pulakeshin's son
Vikramaditya I. The Gangas probably hoped to gain Chalukya support against the
Pallavas, who had captured the
Kongunadu region from them. The Gangas subsequently defeated the Pallava ruler Kaduvetti of Kanchi. In return, Shilabhattarika, a daughter of Pulakeshin II was married to Dadiga, a son of Mokkara (Mushkara) and grandson of Durvinita, as attested by a copperplate charter of Chalukya Vijayaditya dated January–February 717 CE. Shreenand L. Bapat of
Bhandarkar Oriental Research Institute, who deciphered this inscription, identifies her with the renowned Sanskrit poet
Shilabhattarika.
Mauryas of Konkana Pulakeshin's father Kirttivarman had defeated the
Mauryas of Konkana (modern
Konkan), who ruled in the coastal region of present-day Goa and Maharashtra. The Mauryas acknowledged the Chalukya suzerainty during Mangalesha's reign, but seem to have declared independence during the Chalukya war of succession. After consolidating his power in southern Deccan, Pulakeshin successfully besieged the Mauryan capital Puri, which is variously identified as
Gharapuri (Elephanta) or Rajapuri (near
Janjira).
Latas, Malavas, and Gurjaras The Aihole inscription states that Pulakeshin subjugated the
Latas, the
Malavas, and the
Gurjaras, who were the northern neighbours of the Chalukyas. Historian Durga Prasad Dikshit theorizes that these kingdoms may have accepted Pulakeshin's suzerainty without a military conflict, when faced with an invasion from the northern king
Harshavardhana. Alternatively, it is possible that these three rulers accepted Mangalesha's suzerainty after his victory over the
Kalachuris, and the Aihole inscription simply refers to Pulakeshin reaffirming the Chalukya suzerainty over them. The Lata region (present-day southern Gujarat) was formerly under the control of the Kalachuris, who had been defeated by Mangalesha. Pulakeshin, who appears to have annexed Lata to the Chalukya kingdom, placed it under the governorship of a member of the Chalukya family. The rule of the Chalukya governor Vijaya-varma-raja over Lata is attested by his 643 CE
Kheda copper-plate inscription. The Malavas ruled in and around the present-day
Malwa (Malava) region in central India. According to the Chinese traveler Xuanzang, Malava ("Mo-la-po") was an independent kingdom, but the records of the
Maitraka dynasty suggest that the Maitrakas controlled at least a part of the Malava territory. Thus, the Malavas may have been Maitraka vassals or independent rulers before they accepted Pulakeshin's suzerainty. The Gurjaras were most probably the
Gurjaras of Lata (or Bharuch), and the Gurjara ruler who accepted Pulakeshin's suzerainty was probably Dadda II.
Victory over Harsha The most notable military achievement of Pulakeshin was his victory over the powerful emperor
Harsha-vardhana, who ruled over much of northern India. The inscriptions of Pulakeshin's successors prominently mention this victory even when they ignore his other military achievements.
Date The date of the war between Harsha and Pulakeshin has been debated by modern scholars. The Kandalgaon copper-plate inscription, dated to Pulakeshin's fifth regnal year (), mentions the conflict, but this inscription is regarded as spurious by modern scholars. Some scholars, such as
K. V. Ramesh and
K. A. Nilakanta Sastri, date the battle to or before, based on the 612–613 CE Hyderabad inscription of Pulakeshin. This inscription boasts that Pulakeshin defeated a king who had fought a hundred battles (presumably Harsha). The later Chalukya inscriptions, dating from the reign of
Vikramaditya I onwards, mention Pulakeshin's victory over Harsha using similar expressions. This early date for the war is also supported by the writings of Xuanzang, who states that Harsha fought wars for six years, and then ruled in peace for thirty years. Scholars Shreenand L. Bapat and Pradeep S. Sohoni date the battle to the winter of 618–619 CE. These scholars note that the Bijapur-Mumbai grant inscription, dated 4 April 619 CE, mentions Pulakeshin's victory over Harsha, which proves that the conflict definitely took place sometime before this date. The earlier Satara inscription of Pulakeshin's brother
Vishnu-vardhana, issued during his eighth regnal year () does not mention the conflict. Based on this, Bapat and Sohoni theorize that the conflict took place between November 618 CE and February 619 CE. Some earlier scholars, such as D. Devahuti dated the conflict to 630s CE, but this is no longer considered correct after the publication of the Bijapur-Mumbai inscription in 2017.
Cause of the war The cause of the war between Harsha and Pulakeshin is not certain. Historian
K. A. Nilakanta Sastri suggests that Harsha's growing influence may have driven the Latas, the Malavas, and the Gurjaras to accept Pulakeshin's suzerainty. Historian Durga Prasad Dikshit adds that these three kingdoms are known to have been enemies of Harsha's father
Prabhakara-vardhana, as attested by Harsha's court poet
Bana: this enmity probably continued during the reign of Harsha. The Malava king played a role in the murder of Harsha's predecessor
Rajya-vardhana, and also killed Harsha's brother-in-law, the
Maukhari ruler Graha-varman. The
Gurjara ruler Dadda II aided the
Maitraka dynasty against Harsha. When Harsha decided to take action against these three kingdoms, their rulers probably sought the protection of Pulakeshin. Pulakeshin may have granted asylum to Harsha's adversaries. According to scholars Shreenand L. Bapat and Pradeep S. Sohoni, the "Malavas" mentioned in the Chalukya record were the
Later Guptas who controlled the
Malwa region. The expansion of the
Maitraka influence in the Malwa region must have attracted Harsha's attention. The Maitraka ruler Shiladitya I may have sympathized with Pulakeshin's cause during the latter's northern campaign against the Latas, the Malavas, and the Gurjaras. This situation ultimately resulted in a conflict between Harsha and Pulakeshin. Another possibility is that Harsha decided to take advantage of the turmoil resulting from the conflict between Mangalesha and Pulakeshin, and invaded the Chalukya kingdom. During his march against Pulakeshin, Harsha advanced up to the
Narmada River before being forced to retreat.
Result The Aihole inscription of Pulakeshin boasts the
harsha (mirth) of Harsha melted away by fear, as his elephants fell in the battle. The only other inscription from his reign that mentions this battle is the Bijapur-Mumbai inscription. Harsha's court poet Bana does not mention this conflict in his biography
Harsha-charita, presumably to avoid portraying his patron in a negative light. However, Pulakeshin's success against Harsha is confirmed by other independent sources. The Chinese traveler
Xuanzang, who calls Pulakeshin's kingdom Mo-ho-la-cha (the Chinese transcription of "Maharashtra"), provides evidence of Pulakeshin's success against Harsha. Xuanzang states that Shiladitya (that is, Harsha) had conquered the nations from east to west, and had marched with his army to remote parts of India: only the people of Mo-ho-la-cha had refused to accept his suzerainty. Xuanzang further states that Harsha gathered troops from different parts of his kingdom, summoned his best commanders, and led the army to punish the people of Mo-ho-la-cha, but could not subjugate them. The
Rashtrakutas, who ultimately overthrew the Chalukyas several years after Pulakeshin's death, also boast that they defeated the dynasty that claimed victory over Harshavardhana, thus indirectly confirming Pulakeshin's achievement. The Aihole inscription poetically states that Pulakeshin's elephants had to avoid the neighbourhood of the
Vindhya mountains beside the Narmada River, because they "by their bulk, rivalled the mountains". Historian K. A. Nilakanta Sastri interprets to mean that Pulakeshin "did not send his elephant forces into the difficult Vindhya terrain", and guarded the passes with infantry. According to Shreenand L. Bapat and Pradeep S. Sohoni, the inscription suggests that Pulakeshin's army subsequently tried to cross the
Vindhyas, in a bid to invade Harsha's kingdom, but was unsuccessful, which may explain why only two inscriptions from Pulakeshin's reign mention his conflict with Harsha.
Dakshina Kosala and Kalinga The Aihole inscription states that the rulers of Koshala and Kalinga accepted Pulakeshin's suzerainty without offering any resistance. Koshala here can be identified as
Dakshina Kosala (present-day
Chhattisgarh and western
Odisha), which was probably under the
Panduvamshi rule. The Aihole inscription does not mention the name of the subjugated ruler, but historian
D. C. Sircar theorizes that he may have been the Panduvamshi king Mahashivagupta Balarjuna. The name of the ruler of
Kalinga, which includes parts of present-day
Odisha and northern
Andhra Pradesh, is not certain either. Historian Durga Prasad Dikshit suggests that he was probably a member of the
Eastern Ganga dynasty. Historian K. A. Nilakanta Sastri suggests that he may have been a Vishnukundina feudatory.
Vishnukundina dynasty According to the Aihole inscription and the Maruturu inscription, Pulakeshin invaded and captured
Pishtapura (modern Pithapuram in Andhra Pradesh). The Maruturu inscription suggests that this event took place around or before 617–618 CE. The Aihole inscription states that subsequently, a fierce battle was fought near Kunala lake (identified with modern
Kolleru Lake), whose water turned red with the blood of those killed in the war. These inscriptions do not name Pulakeshin's rival in these conflicts, but modern scholars identify him as a king of the
Vishnukundina dynasty, which ruled in Andhra Pradesh. Pulakeshin probably subjugated Vishnukundina vassals during his eastern campaign in Kalinga, which may have brought him in conflict with the Vishnukundina dynasty. Pulakeshin conquered the Vishnukundina kingdom, located in the lower
Godavari-
Krishna valley, and appointed his younger brother 'Kubja'
Vishnu-vardhana as the governor of the newly conquered territory. The Chalukya conquest in this region is corroborated by Vishnu-vardhana's 631 CE Kopparam copper-plate inscription, which records a land grant in the Karma-rashtra region of present-day Andhra Pradesh. The Vishnukundina ruler defeated by Pulakeshin was probably Indravarman: he appears to have ultimately accepted Pulakeshin's suzerainty, and was allowed to rule as a Chalukya vassal. Pulakeshin assigned some of the newly conquered territories to his own feudatories. For example, the Maruturu inscription states that the Aluka ruler Gunasagara, a Chalukya vassal, came from Mangalapura (identified with modern Mangalagiri in Guntur district) to Kallura after undergoing several hardships. == Xuanzang's visit ==
