Śakraditya

Śakraditya (Śakrāditya, शक्रदित्य) is the royal figure whom the Chinese pilgrim Xuanzang and later Buddhist sources name as the builder of the first monastery at Nālandā in Magadha, the monastic complex that grew into the great Buddhist center of learning. Xuanzang, writing in the 7th century, says Śakrāditya was "a former king of this country" who, "soon after the decease of the Buddha," built a monastery there¹⁰. Many modern scholars identify him with the Gupta emperor Kumāragupta I (c. 415–455 CE), whose imperial title Mahendraditya shares with Śakra a reference to the god Indra, but the identification is not beyond doubt, and the exact date and even the nature of his foundation remain open questions¹.

Key fact	Detail
Traditional role	Builder of the first monastery at Nālandā, according to Xuanzang (7th c.) and Prajñāvarman (8th c.)¹⁰
Usual identification	Kumāragupta I (c. 415–455 CE), whose title Mahendraditya matches Śakra as a name of Indra¹^•²
Recorded successors	Buddhagupta, Tathāgatagupta, Bālāditya, and Vajra, each adding monasteries³
Dating bounds	After Faxian's visit (before c. 411 CE); Kumāragupta I's inscriptions bound his reign at 415–16 and 448–49 CE; the oft-cited 427 CE is a modern estimate¹^•⁴
Epigraphic trace	A clay seal from the site with a legend naming Śakrāditya, read as evidence he built a vihāra there¹⁰
Archaeological complication	Excavations at Jagdishpur, Jaffaradih, and Caitya 3 have led B. R. Mani to suggest Buddhist occupation from the 3rd century BCE, before Śakrāditya¹⁰

Sources for the life and foundation

The tradition rests on texts written centuries after the events they describe. Xuanzang, who studied at Nālandā in the 7th century, gives the fullest account in his Datang Xiyu ji and names Śakrāditya as the first of a line of royal builders¹⁰. The Korean monk Prajñāvarman, visiting Nālandā about four decades after Xuanzang, repeated the same narrative that Śakraditya founded a monastery there¹⁰.

The gap between the sources and the events is the central problem of reliability. Xuanzang places Śakrāditya "not long after the time of the Buddha's parinirvāṇa," a dating scholars consider impossible: no such early archaeological evidence exists at Nālandā, and no ruler named Śakrāditya is known before the Guptas³. His biographer's figure of 700 years since the foundation, as the translator Samuel Beal reckoned it, would put the founder around the 1st century BCE⁵. Max Deeg, a specialist on Xuanzang's account, concludes on balance that Xuanzang is a relatively reliable witness to a Buddhist historiographical tradition linking Gupta kings, especially Bālāditya, with patronage of Nālandā, while his absolute chronology is not³.

The traditional account of the foundation

In Xuanzang's telling, Śakrāditya chose the Nālandā site by augury and built the first monastery there⁶. His son Buddhagupta (Fotuojuduo in Chinese, "Awakened-Protection") followed him on the throne and built another monastery further to the south³. Tathāgatagupta added one to the east, Bālāditya one to the northeast, and Bālāditya's son Vajra one to the west⁶. By Xuanzang's time the complex held ten thousand monks in six buildings erected by as many monarchs, and the monastery of Nālandā had lasted through more than seven centuries⁷.

The list of builders runs Śakrāditya–Bu(d)dhagupta–Tathāgatagupta–Bālāditya–Vajra, and two of these names are recognizable Gupta rulers: Budhagupta, and Bālāditya, the epithet or biruda of Narasiṃhagupta³. Bālāditya Narasiṃhagupta (c. 500 CE) is also credited in the tradition as the restorer of the institution after the Huna ravage by Mihirakula⁴. Buddhist sources disagree on Bālāditya's position in the line: Xuanzang makes him Budhagupta's grandson, the Mañjuśrīmūlakalpa makes him son of Kumāragupta and father of Budhagupta, and the Life of Vasubandhu makes him son of Vikramāditya (Candragupta II)³.

Who was Śakraditya? The identification debate

The Kumāragupta I case. Father H. Heras, a Jesuit historian, argued in 1928 that Śakraditya is a title of Kumāragupta I, since Śakra and Mahendra are both names of the god Indra and Kumāragupta's coins carry the title Mahendraditya; counting reigns from Bālāditya, he placed the foundation about 427 CE². Many scholars, citing Xuanzang, have followed this identification¹⁰. Gupta kings were known by variant names, which makes such a double naming plausible⁸. Archaeology supports Kumāragupta's connection to the site: Archer-type seals of Kumāragupta I found at the north end of the eastern verandah of monastery site no. 4 are among the earliest finds from Nālandā⁴, and Hirananda Sastri's 1942 ASI memoir published a clay sealing from the site naming Shakraditya alongside seals of later Gupta rulers such as Budhagupta⁵.

The case for caution. The identification is not beyond doubt, because Xuanzang places Budhagupta, a late-5th-century Gupta king, immediately after Shakraditya in his list¹. Michael Willis and Deeg argue that historians' obsession with identifying each of Xuanzang's kings with one Gupta ruler has led to questionable historical results and has created some mess in the reconstruction of the Gupta lineage; Deeg proposes treating Xuanzang's list as an "idealized" lineage of rulers rather than forcing it to match inscriptional lineages³. Deeg also notes that if Budhagupta and Tathāgatagupta are the same ruler, Bālāditya would rather be Kumāragupta II³. A further complication is that the succession after Kumāragupta I is itself uncertain: it is widely accepted that Skandagupta did not accede peacefully, and it is not certain the succession was immediate, since there is a gap between the known dates of the two reigns⁹.

By the numbers: dating the foundation

The traditional attribution is commonly placed in the 5th century, but archaeological interpretations and proposed dates remain contested.

Faxian's silence. The Chinese pilgrim Faxian, who toured India during 400–411 CE and passed through Magadha in the first decade of the 5th century, mentions at the village of Nala only a stupa and no monastery, suggesting the monastery was founded after his visit¹.
Inscriptional bounds. The Bilsad stone inscription (415–16 CE) and Mankuwar inscription (448–49 CE) give the earliest and latest assignable dates of Kumāragupta I's reign, so a foundation under him falls in a window of roughly 420–448 CE, with a rough date of 425 CE proposed; it cannot be pushed earlier than 415–16 CE⁴.
The 427 figure. The year 427 CE, repeated in many accounts of the founding, is a modern estimate, not a fixed date; keeping Xuanzang's list of kings but dropping his dates, the Gupta names and seals settle a 5th-century founding⁵.
Cunningham and Ghosh. Alexander Cunningham put the date of Nālandā Mahavihāra between CE 425 and 625, after Faxian's visit and before Xuanzang's arrival; Amalananda Ghosh placed the beginning of Monastery 1 in the early sixth century on palaeographic grounds¹⁰.
Earlier strata. B. R. Mani's excavations at Jagdishpur and Jaffaradih led him to suggest a beginning in the third century BCE, and the earliest stratification from Caitya no. 3 at Nālandā belongs to the 3rd century BCE, indicating that vihāras at Nālandā predate Śakrāditya¹⁰. This stands against Sastri's 1942 finding that no relic from the site could definitely be dated before the Imperial Guptas²; the two positions remain unreconciled.

On this evidence, the 2022 study in Ancient Asia argues that Śakrāditya built a new vihāra within an already existing complex rather than founding Nālandā outright¹⁰, a reading that preserves Xuanzang's tradition about the king while revising what "founder" meant.
