Khasa Malla (Sinja) Kingdom of Western Nepal: A Karnali History Explainer

The Khasa Malla kingdom was a medieval state that dominated the Karnali-Bheri river basin of far-western Nepal and adjoining parts of western Tibet from about the 12th to the 14th century AD. It is named after the Khas people, and 'Malla' was a royal title its rulers adopted; Tibetan sources call the realm 'Ya-tse' (Yatse), reflecting the dynasty's Himalayan and trans-Himalayan connections. Because both dynasties used the surname 'Malla', this kingdom is frequently confused with the far better-known Malla kings of the Kathmandu Valley, but the two were entirely separate states, cultures and periods.

The kingdom's political heart was the Sinja Valley (Semja or Sija) in present-day Jumla District, with a second, warmer administrative and winter capital at Dullu in modern Dailekh District. From these twin centres the Khasa Mallas controlled trade routes linking the Gangetic plains with the Tibetan plateau, exchanging grain, wool, salt and Himalayan goods. Their archaeological footprint survives today across the Jumla, Surkhet and Dailekh districts.

At its height the kingdom projected power far beyond the Karnali hills. Inscriptions and traditions record Khasa Malla authority reaching the Guge and Purang districts of western Tibet, pilgrimage patronage in the Indian plains, and, under later kings, influence eastward toward the Gandaki region. This made it, for a time, the pre-eminent power of the western Himalaya before the rise of the Shah kingdom of Gorkha several centuries later.

The Sinja Valley lies along the Sinja (Hima/Tila) river in Jumla, high in the Karnali highlands. Excavations here and at nearby sites have exposed the remains of royal palaces, temples, and a planned settlement served by an elaborate water-supply system of earthen pipes, alongside monolithic stone columns, Buddhist chaityas, and cliff-face inscriptions. The temples of Kanaka Sundari and Tripura Sundari at Sinja remain living centres of local worship and are tied to the region's Khasa Malla religious traditions.

Because the earliest datable examples of Nepali written in the Devanagari script cluster around Sinja and Dullu, the valley is popularly celebrated as the birthplace of the Nepali language. To formally protect and recognise this heritage, Nepal's Department of Archaeology nominated the Sinja Valley to the UNESCO World Heritage Tentative List; it was added on 30 January 2008 under reference number 5263, in the cultural category.

The tentative-list nomination advances two UNESCO criteria: criterion (ii), for the valley's role in the significant exchange of human values across the Himalaya, and criterion (iii), for bearing exceptional testimony to the cultural traditions of the Khasa civilisation. Archaeological work to establish the site's authenticity has been carried out by the Department of Archaeology in partnership with researchers from the University of Cambridge.

According to the genealogy inscribed by King Prithvi Malla, the dynasty was founded by Emperor Nagaraja (also called Javeshwara), traditionally placed around the late 11th to early 12th century, roughly six generations before King Krachalla. The early kings bore the '-challa' name-ending and were largely Buddhist, patronising monasteries and leaving records across the Himalayan frontier.

The line then passed through a succession of powerful rulers. Krachalla (early 13th century) campaigned in the Kumaon-Garhwal region of present-day Uttarakhand. Ashoka Challa (Asokachalla), active in the mid-to-late 13th century, is known from donative inscriptions at Bodh Gaya in India, underlining the kingdom's Buddhist patronage and long-distance reach. Later kings including Jitari Malla, Ripu Malla and Aditya Malla continued to expand and consolidate; Ripu Malla famously left his mark by inscribing his name on the Ashoka pillars at Lumbini and Nigalihawa.

The most celebrated ruler was Prithvi Malla, active in the mid-14th century, under whom the kingdom is generally reckoned to have reached its greatest extent, spanning Guge and Purang in the west and Nepalese territory eastward. His reign marks the culmination of the Khasa Malla state and the shift from Buddhist to increasingly Hindu royal ritual that characterised its final phase.

The single most important record of the kingdom is the Dullu stone-pillar inscription of King Prithvi Malla, dated 1279 Shaka Samvat (equivalent to about 1357 AD) and located at Dullu in Dailekh. Rediscovered and published by the scholar-yogi Naraharinath, it sets out the royal genealogy (vamshavali) tracing the dynasty back to Nagaraja and is the foundation on which historians reconstruct the king-list of the Khasa Mallas.

Beyond the Dullu pillar, the Khasa Mallas left a comparatively rich epigraphic trail: stone and copperplate inscriptions recording land grants, temple endowments and royal decrees are found across Jumla, Dailekh and Surkhet, and Khasa Malla royal inscriptions survive as far afield as Bodh Gaya and the Lumbini-area Ashoka pillars. These documents are prized not only for their political content but for their language.

The dialect of these inscriptions is an early, 13th-14th-century form of modern Nepali, making them among the oldest written attestations of the language. For this reason the Khasa Malla era is treated by linguists as the formative period of Nepali, with the earliest 'proto-Nepali' forms clustering around Dullu, the imperial winter capital, and the Sinja Valley.

Nepali began as 'Khas kura', the speech of the Khas people of the Karnali region, and it is from the Khasa Malla heartland that its earliest written records survive. The kingdom's official languages were the Khas vernacular and Sanskrit, and the spread of Devanagari-script Khas writing under royal patronage in the 13th and 14th centuries seeded a literary tradition that later travelled east with Khas migration and, ultimately, with the unification of Nepal.

This is why Sinja and Dullu are so central to Nepali cultural identity: they anchor the language that today serves as Nepal's lingua franca to a specific medieval homeland in Karnali, rather than to Kathmandu. The popular slogan calling Sinja 'the cradle of the Nepali language' rests on this documented concentration of the oldest datable Nepali inscriptions.

It is worth stating the claim carefully. Sinja and Dullu preserve the earliest attested written Nepali, and the Khasa Malla period is the language's formative literary era; this is well supported by the surviving epigraphy. Precise origins of any language are gradual and debated, so 'origin of the Nepali language' is best understood as the origin of its earliest written record rather than a single dateable birth.

From the late 14th century the Khasa Malla state weakened and fragmented. As central authority dissolved, local Khas chieftains and elites carved out sovereign petty kingdoms across the rugged Karnali-Bheri basin. This cluster of roughly twenty-two principalities became known as the Baise Rajya ('twenty-two kingdoms'), the direct political successors of the Khasa Malla realm in western Nepal.

A parallel cluster of about twenty-four principalities, the Chaubise Rajya, emerged further east in the Gandaki basin. Among the Baise states, Jumla itself rose to prominence under the Kalyal (Kallal) dynasty; tradition holds that this line was established in the early 15th century when a ruler named Baliraja succeeded through marriage into the family of the last Ya-tse (Khasa Malla) king, providing a dynastic bridge from the old empire to the new order.

The Baise principalities retained varying degrees of independence for centuries. They were finally absorbed one by one into the modern Nepali state during the Gorkha-led unification campaigns of the later 18th and early 19th centuries, ending the long medieval political tradition that the Khasa Mallas had begun in the Karnali hills.

Sinja lies in a remote part of Jumla District in Karnali Province, reached overland from Jumla's district headquarters at Khalanga (near the Chandannath temple) via mountain road and trail. The area is high-altitude Himalayan terrain, and travel is seasonal and weather-dependent, so visitors should plan around road and flight conditions and local advice.

For heritage travellers and researchers, the draw is the combination of archaeological ruins, cliff inscriptions and living temple traditions in a landscape that is itself part of the story. Local festivals and jatras connect present-day communities in the Kanakasundari area and Jumla to the region's Khasa Malla past.

As a UNESCO tentative-list site, Sinja Valley continues to face conservation challenges typical of remote archaeological landscapes, including exposure, limited resources and access. Ongoing documentation by the Department of Archaeology and academic partners aims to strengthen the case for full World Heritage inscription and to safeguard the physical remains of the kingdom that gave Nepal much of its early written language.
