The First Battle of Eran was a key engagement of the First Hunnic War that took place in 498 CE at Airikana (Eran), India. It was fought between the Gupta Empire and the invading army of Alchon Huns. The battle involved the Emperor Budhagupta, his viceroys, and Toramana, an acclaimed Hunnic king. The confrontation had significant consequences for the political and territorial situation in the region. The conflict concluded with a victory for the Alchon Huns that influenced subsequent events in the region.
Prelude.
The invasion of the Hepthalites followed a geographical trajectory similar to that of the Indo-Greeks during the post-Maurya period and was later mirrored by the Turks. Like the Indo-Greeks and the Turks, the Hunas initially consolidated their power in the Punjab region. After their defeat by Skandagupta, they shifted their focus back to Persia. In 456 CE, Yazdegerd II continued his struggle against them. Following his death in 457 CE, the Sassanian Empire came under the rule of Peroz I, who was defeated by the Hephthalite king Akun (or Akhshunwar) and forced to pay tribute.
In 484 CE, Peroz I launched an offensive against the Hephthalites but was defeated and killed. According to Chavannes, based on Chinese historical accounts, by around 500 CE, the Huna Empire included Tokharistan, Kabulistan, and Zabulistan, with Gandhara and Chitral being the only regions of "India proper" under their control. The Chinese traveler Song Yun, who visited Gandhara in 520 CE, provided further details on the state of the region during that time:
Song Yun's account suggests that the power of Jaūvla extended to Gandhara approximately two generations before his visit in 520 CE. The identity of the Huna king who led the conquest of Gandhara remains uncertain. However, it is plausible that King Ramanila, known only from his coins, preceded Toramana and played a key role in the Huna conquest of the region. Nevertheless, it cannot be ruled out that Ramanila belonged to a different dynasty than that of Toramana.[[File:Toramana portrait and initials Tora.jpg|190px|center|thumb|
[[Toramana]], a prominent ruler of the [[Alchon Huns|Alchon dynasty]], successfully established political and cultural dominance in the [[Punjab]], which fostered his imperial ambitions. During this time, the [[Sasanian Empire]] was in turmoil following a coup against [[Kawad I]] in 496 CE. Although [[Kawad I]] regained power in 498 CE, his authority remained heavily reliant on the [[Hephthalites]], the [[Huns|Hunnic]] rulers north of the [[Hindu Kush]].

Capitalizing on this opportunity, Toramana launched an invasion of northern and western India from the Punjab, possibly from a stronghold on the banks of the [[Chenab River|Candrabhaga River]]. Within a year, he assumed the title of [[Maharajadhiraja]], or Emperor, as evidenced by the inscription on the [[Eran boar inscription of Toramana|Boar of Eran]], which describes him as 'the glorious Toramana, of great fame and great lustre.'
Background.
Toramana's prospect.
[[File:Toramana gold coin circa 490-515.jpg|thumb|255px| The [[Alchon Huns|Alkhans]] gradually expanded their influence in the northwest of the [[Indian subcontinent]] during the latter half of the 5th century. This culminated with [[Toramana]]'s rise to power as the leader of the Alkhan quadrumvirate, declaring himself "King of Kings" ([[Rajadhiraja]]) as evidenced by the. [[Khurai|Khura]] Stone Inscription. By the close of the century, the Alkhan had significantly integrated into Indian society and culture. According to [[Hans T. Bakker|Bakker]], this integration may have fueled Toramana's ambitions for territorial expansion, guided not by the supposed ferocity often attributed to the [[Huns]], of which there is scant evidence, but by principles from the Indian Book of State, which emphasized the ideal ruler's duty to pursue conquest.
Toramana's campaign.
[[Toramana]] emerged as a formidable and charismatic leader with exceptional military skills. His dominance over rival [[Huns|Hunnic]] factions, forcing them into subordinate roles, and his strategic establishment of Parvatikā on the [[Chenab River|Chenab]] (Candrabhaga) River in [[Punjab]] as his operational base underscore his tactical acumen. His rapid military campaigns resulted in the conquest of large areas of northern and western India within a few years, culminating in the construction of the [[Goparaja]] funereal monument in AD 510.
Battle.

This conflict, which [[Hans T. Bakker|Bakker]] refers to as the First Hunnic War, began with a campaign led by [[Toramana]] around AD 498. The [[Alchon|Alkhan]] king invaded the [[Doab#The_Doab|Ganga–Yamuna Doab]], capturing [[Mathura]], crossing the [[Yamuna]] near [[Kalpi]] (Kalapriyanatha), and advancing south into the [[Betwa]] valley to attack the western territories of the [[Gupta Empire]]. The [[Eran]] Pillar inscription of [[Budhagupta]] from Gupta Year 165 (AD 484) mentions Suraśmicandra, the Gupta viceroy of these territories, who claimed to govern the region between the [[Ganga]] and [[Narmada]] rivers. Suraśmicandra confronted [[Toramana]] alongside [[Budhagupta]] in the battle.
[[File:Eran Budhagupta inscription.jpg|250px|thumb|
The [[Budhagupta]] inscription is dated to 484–485 CE. It is a [[Vaishnava]] inscription. It describes that the Gupta kingdom stretched from Kalindi River to Narmada River, that the inscription marks the raising of a column in honour of [[Janardana]], another name of [[Vishnu]].
[[File:Eran Budhagupta pillar built circa 476–495 CE.jpg|thumb|upright=1|left|
The two powers eventually clashed in the fertile plains around [[Eran]], also known as Airikana, or the "Refreshing Fields," where the [[Betwa]] and [[Bina River (India)|Bina]] rivers meander. On the southern banks of the Bina, [[Budhagupta]] had overseen of a religious complex dedicated to [[Vishnu]], the [[Gupta Empire]]’s tutelary deity. In this area, two local feudatories, Maharaja [[Mātṛviṣṇu]] and his younger brother [[Dhanyaviṣṇu]], had constructed a twin temple, which was guarded by a 13-meter-high pillar, the 'Column of [[Janardana]]' (Vishnu/Krishna). 
The two inscriptions discovered at [[Eran]] provide valuable insight into the period. The first inscription, dated to 484 CE, records a pious construction by Maharaja [[Mātṛviṣṇu]] and his younger brother [[Dhanyaviṣṇu]] during the reign of [[Budhagupta]]. The second inscription, however, documents [[Dhanyaviṣṇu]]'s construction of a temple after his brother’s death, in the first year of Rajadhiraja Maharaja [[Toramana]] Sahi Jauvla's rule. This suggests that [[Dhanyaviṣṇu]], a prominent official, abandoned the Gupta emperor during this critical time to offer his allegiance to the [[Alchon Huns|Hunas]]. This shift in loyalty likely occurred sometime after 484 CE, but within a generation.
The Kuvayamālā, a jain work composed in 778 CE, mentions Harigupta, linked to the [[Gupta dynasty]], as the mentor of [[Toramana]]. It also notes another of his students, Devagupta, who is referred to as a royal sage ([[Rajarshi]]). Furthermore, copper coins found in the [[Ramnagar, Varanasi|Ramnagar]] area, which was part of the ancient [[Panchala]] region, suggest the presence of a ruler named Maharaja Harigupta, who is believed to have been active around 500 CE. Harigupta, likely a scion of the Gupta imperial family, is believed to have established himself in northern Panchala. The reasons for his potential alliance with the Huna invaders are not fully explained by the available historical sources.
Legacy.

The first battle of Eran, fought under the banner of the [[Garuda|Imperial Eagle]], marked a substantial defeat. During the early phase of his campaign, [[Toramana]] adopted the title [[Maharajadhiraja]], as recorded in the [[Eran boar inscription of Toramana|Eran Stone Boar Inscription]] superseding his earlier title [[Rajadhiraja]], mentioned in the [[Khurai|Khura]] Stone Inscription. This elevated title had traditionally been associated with the [[Gupta Empire|Gupta]] emperors, symbolizing Toramana’s assertion of imperial authority. 
After these events, the local ruler [[Dhanyaviṣṇu]] was compelled to decide between submitting to [[Toramana]]’s rule or facing death. He chose submission. Although the power of the former empire had waned, a sense of resilience persisted. This resilience was reflected in the completion of a 3.5-meter-high [[Varaha]] statue, a representation of the boar incarnation of [[Vishnu]], which [[Dhanyaviṣṇu]] was allowed to finish.

The monument reflects [[Dhanyaviṣṇu]]'s devotion to [[Vishnu]], who, according to the [[Mahabharata]], rescued the earth during times of cosmic distress by lifting it on his tusks. [[Toramana]], noted for his favorable stance toward [[Vaishnavism]], may have viewed the statue’s symbolism as aligning with the moment’s significance circumstances.
Aftermath.
Toramana's endeavors.
[[Toramana]]'s actions suggest that his goal was not merely to dismantle the [[Gupta Empire]] but to bring it under his dominion. After consolidating control over the western territories, the [[Alchon]] king advanced toward the empire's core. Archaeological evidence provides crucial insights into this campaign. Excavations at the ancient city of [[Kaushambi district|Kaushambi]] reveal widespread destruction in its final phase of occupation, indicating a significant attack. Among the findings was a seal impression from the Ghositarama monastery bearing the letters "To Ra Ma Na," likely linking the devastation to Toramana. The evidence also suggests that Kaushambi never fully recovered from this event.
Access to Arabian sea.

[[Toramana]]'s numismatic and epigraphic records demonstrate his appreciation for [[Indian culture]], which is also reflected in his military campaigns in [[Rajasthan]] and [[Gujarat]]. Seeking to control the western trade route from [[Mathura]] to the [[Arabian]] Sea, Toramana launched an expedition in his second or third year, passing through Madhyamika (Nagari) and Dasapura ([[Mandasor]]) toward Bharukaccha (modern [[Bharuch]]) on the [[Gulf of Cambay]]. Along this route was Vadrapali, a significant trade center mentioned in three copper plates, likely corresponding to the modern town of [[Sanjeli]] in North Gujarat, where the plates were discovered.

[[Sanjeli]]'s unique geographical features, surrounded by low, rocky mountains that formed natural fortifications, made it an ideal strategic site for caravans traveling to the coast. Demonstrating his organizational abilities, [[Toramana]] appointed Bhuta as governor of the Sivabhagapura district, located about 1,000 kilometers south of his Panjab homeland. The first [[Sanjeli inscriptions|Sanjeli copper plate]] records that—

[[Toramana]]'s route through [[Rajasthan]] and [[Gujarat]] appears to have followed the ancient caravan track from [[Mathura]] to the [[Gulf of Cambay]], bypassing the eastern [[Betwa]] valley route taken in his earlier invasion.This is supported by the location where the [[Sanjeli inscriptions|Sanjeli copper plates]] were found, which may have been a town in the Sivabhagapura district, and the list of merchants involved in the tax agreement, hailing from places connected by these trade routes. Within three years of the Battle of Eran, Toramana had secured control over major trade routes in western India, effectively linking the [[Central Asian]] trade network, controlled by his [[Hephthalite]] allies, with India’s commercial infrastructure and its key seaports on the [[Arabian Sea]]. His power was derived not from plunder, as often suggested, but from his control over this expansive transnational trade network.
