The Forgotten Kingdoms That Gave Birth to Angkor

Long before Jayavarman II proclaimed Cambodia's independence on Mount Kulen in 802 and laid the first stone of the Khmer Empire, the Mekong Delta and surrounding plains had already given rise to powerful kingdoms, largely forgotten by the general public today. Funan, then Chenla, spent nearly seven centuries shaping the political, religious, and commercial foundations on which Angkor would later rise.

Funan, the first known kingdom

The kingdom of Funan emerged around the 1st century CE in the Mekong Delta, straddling present-day Cambodia and Vietnam. What we know of Funan rests almost entirely on the chronicles of China's Wu dynasty, whose envoys Kang Tai and Zhu Ying left detailed accounts in the 3rd century — no Funanese inscription in a local language has survived to this day.

Chinese texts recount Funan's founding legend: an Indian brahmin named Kaundinya is said to have married a local princess, Soma, uniting Indian and indigenous influences that would go on to shape Khmer civilization for centuries. Funan became a major trading crossroads on the maritime route linking India to China, with its main port at the archaeological site of Oc Eo, where Roman coins and objects of Persian and Indian origin have been found — evidence of its early integration into Eurasian trade networks.

It was also during this period that Hinduism and Buddhism took lasting root in the region, along with a Sanskrit-derived script that would later form the basis of Khmer writing.

Chenla, the shift inland

From the 6th century onward, power gradually shifted inland, to the area of present-day Cambodia around the Tonlé Sap and Wat Phou, in what is now Laos. Chinese chronicles refer to this new political entity as Chenla, described as a former vassal of Funan that eventually supplanted it.

Unlike Funan, Chenla left its own inscriptions in Sanskrit and Old Khmer, offering a direct window into its political and religious organization. The kingdom nonetheless underwent significant fragmentation in the 8th century, traditionally described by historians as a split between a northern "Land Chenla" and a more southern "Water Chenla," the latter exposed to Javanese incursions.

802: the birth of the Khmer empire

It was against this backdrop of fragmentation that Jayavarman II managed, around the turn of the 9th century, to reunify the Khmer principalities and free them from outside overlordship, most likely Javanese. The ceremony he held on Mount Kulen in 802, during which he proclaimed himself "devaraja" — universal sovereign by divine right — is conventionally regarded as marking the start of the Angkorian period.

A continuity stronger than once believed

The foundations laid by Funan and Chenla — Hinduism, irrigation systems, writing, trade networks, and the very notion of sacred kingship — did not vanish with the rise of Angkor; they formed its bedrock instead. The devaraja cult instituted by Jayavarman II was, in fact, no invention out of thin air: it drew directly on Shaivite traditions already present under Chenla, where several rulers had already had royal lingas erected as symbols of the fusion between earthly and divine power. Jayavarman II systematized and centralized this practice, making it the theological and political axis of his new state.

Modern historiography, in fact, tends to qualify the notion of a clean break between Chenla and the Angkorian empire. Archaeological research conducted since the 1990s, particularly around Sambor Prei Kuk (Chenla's capital in the 7th and 8th centuries), reveals a far stronger urban, architectural, and administrative continuity than once assumed. Sambor Prei Kuk's brick temples, with their octagonal towers and carved lintels, already foreshadow certain stylistic motifs that would later be amplified in classical Angkorian art. Likewise, the water-management systems that Angkor would perfect on a monumental scale — barays, canals, reservoirs — find their earliest prototypes in the hydraulic works of Chenla and, before it, of Funan, whose canals in the Mekong Delta rank among the oldest known irrigation works in Southeast Asia.

After 802, Jayavarman II moved his capital several times — Indrapura, Hariharalaya, then Mahendraparvata on the Kulen plateau — before his successors permanently established power in the Angkor region proper, around the Tonlé Sap. It was only with Yasovarman I, at the end of the 9th century, that the first true Angkorian city, Yasodharapura, was born. But the founding act, in Khmer memory as in historiography, remains the ceremony of 802: it symbolically sealed the end of centuries of overlordship and fragmentation inherited from Funan and Chenla, and opened the way to five centuries of Angkorian dominance over mainland Southeast Asia.

Why this history still matters today

For many Cambodians, national identity remains tightly bound to Angkor Wat, omnipresent even on the national flag. Funan and Chenla, lacking equally spectacular temples to show for themselves, remain largely absent from school textbooks and collective memory, even though they laid the very foundations of what would become Angkorian civilization. Recent excavations at Angkor Borei and Oc Eo, carried out notably by Cambodian and international teams, are gradually restoring these kingdoms to their rightful place: not merely a prelude to Angkor, but the bedrock on which the whole of Cambodian history was built. Rediscovering Funan and Chenla is also a way of giving depth to a national story too often reduced to its most photogenic monuments.
