The Monsoon Alliance
The 9th and 10th centuries were for Southeast Asian polities a time of demographic and urban expansion. The concentration of state power allowed for the construction of enormous and enduring temple complexes. Nowhere was this phenomenon more evident than at the heart of Khmer civilization, great Indranokura and her rival and ally, Yasodharapurait, often called Angkor Thom or simply Angkor.
While it may be somewhat obvious to say that climate shaped the development of Khmer civilization, the monsoon system which gave its people life and food presented unique challenges. Much of the immense rainfall which blankets the region comes during a very specific wet season, and harnessing this season was the perennial challenge of those who wished to prosper on the banks of the Mekong. Due to their predictable patterns, the monsoon allowed sustainable agriculture and aquaculture to flourish – and the state perfected it. Mass engineering projects, particularly the construction of canals known as baray, allowed the guilds of Angkor and Indranokura to prosper to unprecedented degrees. Large-scale urbanization to remarkable levels became a hallmark of Khmer civilization.
The hydrological system reached its peak in the late tenth century, providing clean water to the sprawling interlinked system of cities which comprised Indranokura. Run by an indigenous version of the Ayat council system, Indranokuran governance was a byzantine and chaotic system at the best of times. Unlike in India, the guilds here had relatively limited authority – many merchants, craftsmen, and other groups were private individuals, and social mobility although limited was unprecedented for the time. However, the Ayat seats were effectively hereditary, and the monarch was more than a ceremonial figure or a glorified prime minister but a vital religious and political leader. Besides the Ayat, the main seat of power was the temple complex. Local cults syncretized their deities, adopting Hindu names and the overarching religious philosophies as necessary and in turn were granted secular power by local elites eager to use religion to validate their reign.
Part of the reason for the stuttering failure of mercantile guilds to gain control was the collapse of Qi China, which had profound effects on the economy of the entire region. While trade would recover within a century or so, its collapse during a time of political consolidation ensured the domination of religious figures and landholders rather than merchants. Yasodharapurait and Indranokura first signed an alliance in 874. Despite a war three years later, the alliance would be restored, and in union with the city of Vyadhapura, the “Triple Alliance” or Khmer Empire was formed. The Indranokuran Maharaja was notionally placed at the head of the entire system, a symbolic and yet vital link which bound the three cities together through regular visits between all three cities.
While the system might have had some flaws, the demographic advantages of the Khmer in general and the economic and political advantages of the Alliance in particular were overwhelming. Victory after victory was commemorated on temples and monuments to the glory of a series of world conquering Great Kings. Only the Champa dynasty of Vijayapura, shielded as they were by terrain and the Dvaravati city states, strong enough to fight back and form their own coalitions, resisted the centralizing power of Indranokura, and it was Indranokura that emerged as paramount member of the Alliance. By 933, when the terms of the treaty were renegotiated in favor of the Indranokuran Ayats, it was clear where true power lay. Henceforth, most temple dedications were in honor of the Maharaja, rather than local government.
Royal power before the 933 treaty was in many senses secular. The monarch had emerged from a local prominent family, and that family had gradually codified their powers within the framework of a Hindu state. However, after that date, the monarch increasingly became referred to as the devaraja, and sought to connect themselves with various Hindu deities as an incarnation of the divine to grant themselves additional legitimacy and prestige. Despite the centralizing tendencies, the Khmer were a loose and somewhat hegemonic empire. Geography and the uneasy nature of their union meant that symbolic dominion was often more important than actual dominion, and these local governors and councils who watched their names be erased from history in favor of the glorious conquests of a distant despot could rest easy knowing that their actual tangible power was far more difficult to wrest away.
The Khmer Empire did however pose a direct threat to the Srivijaya. By 900, Srivijaya was exhausted, having fought the Silendra dynasty and their partisans to a bloody standstill across Java. Interruptions in Chinese trade and the increasing independence of Srivijayas notional protectorates and partners had rocked the mighty city-state to the core. Local rulers sought their own power-bases, as the Silendra had, and the example set by the Silendra was that it was possible to rebel and at least for a while get away with it. Any punitive victory won by the Srivijayan Empire was rendered hollow by the Silendra dynasty’s escape further east. Word reached the Maharaja’s court that the Silendra exiles now lived in splendid luxury far away, and were no worse for their exile.
The Khmer Empire was one of the more obvious threats. More powerful than any other notional partner of the Srivijaya, the Khmer threat prompted the Srivijaya to begin working with the Dvaravati Raja Narapatisimhavarman providing money and great stockpiles of arms to counterbalance the Khmer and keep them preoccupied. With these generous gifts, Narapatisimhavarman encouraged certain Tai tribes to migrate into the Khorat Basin, distracting the Khmer and leading to several campaigns between 945-955. However, the Tai by and large saw better opportunities to their northeast, and in 957, those who remained, known as the Isan, signed a treaty acknowledging the primacy of Indranokura.
In 960, the Maharaja made a pact with the northern Mon city of Haripunjaya and their king, Chakafadiraj, further isolating the Dvaravati and cutting off their northern overland trade. Slowly, cities began to turn away from the Dvaravati and seek Khmer protection, protection which came with generally lenient terms and was closer to alliance than outright subjugation. However, the core of the Dvaravati kingdom, centered on Nakhon Pathon, refused to submit. Bolstered by a large Srivijayan army (said to number a hundred thousand men and ten thousand elephants) and lead by Sangramadhanan, the son of the famous general Dharmasetu and husband of the Imperial princess Devitanajaya. Sangramadhanan had earned his position thanks to his father’s impressive campaigns against the Silendrans, and though he had inherited his father’s tactical genius he lacked sufficient tact to endear himself to Narapatisimhavarman and indeed had a lofty and overbearing manner which alienated the Dvaravati nobility.
The Khmer invasion, when it came, was well-poised to take advantage of this division in the ranks. While what happened is unclear, it seems that the Srivijayan army was broken independently in a massive battle. Trophies from the victory adorned the walls of Indranokura for the next decade, and Sangramadhanan himself was captured and later executed. The Khmer army defeated Dvaravati roughly a month later and the Khmer enjoyed near total hegemony over Southeast Asia. The rag-tag remainder of the Srivijayan army was evacuated by sea and shortly after this period the city of Chaiya on the Malay peninsula underwent a massive fortification project.
News of this defeat caused a spate of rebellions. The Raja of Kadaram on the peninsula aligned himself with Indranokura, subverting the Srivijayan control of the region. One of the dynasts who had replaced the Silendra, Devasimha Dharmaja launched a successful rebellion on Java. Srivijayan power structures had always been lose and now they were utterly broken. The center of political power in the region would shift rapidly. Cities on the straits would acquire direct influence and Java, far more densely populated than Sumatra, would rise to hegemonic status.
A sign of growing Srivijayan weakness can be seen in the 1018 expedition by an Utkaladeshan navy which brought the once mighty city-state to ruin. Despite holding on as at least a notional hegemon, after that date, political power shifted irrevocably north and east. The city of Temasek on the Malay peninsula negotiated a favorable trade treaty with the Utkaladeshan fleet and henceforth would assume Srivijaya’s position and influence in the region in alliance with the city of Kadaram.
The 11th century was the zenith of the Khmer. Despite increasing strain on the hydraulic systems which enabled their supremacy, Khmer culture and hegemony was unquestionably dominant across a vast region. With the decline of Srivijaya and its fracturing into rival city-states, the Khmer, despite being a primarily land-based power could afford to play kingmakers of sorts, funneling funds to their favored allies and conspiring to bring down those who opposed them.
