Along the valleys of the Mekong and Chao Phraya, a culture of architects, statesmen, warriors, and religious devotees flourished. Overthrow the king of Khmer, build strategic alliances, and settle the score with your historic rivals. Construct the largest religious monument in the world and amass an unstoppable army of devastating siege weapons. The Khmer unique unit is the Ballista Elephant, a mounted scorpion that can be upgraded to fire two bolts simultaneously.
The Khmer are based on the Khmer Empire, whose capital was Angkor (located in present Cambodia), one of the largest pre-industrial cities. At its peak, the city supported one million people. This is reflected by three of their bonuses: Villagers can garrison inside Houses, they do not need to build certain buildings to unlock other buildings or to advance to the next Ages, and food gathered from farming by villagers is instantly collected. Like their Persian and Indian neighbors to the west, the Khmer Empire was known to employ war elephants widely for both tactical and logistical purpose. To reflect this, their Battle Elephants move faster and can be upgraded to deal more damage with the Tusk Swords unique technology.
Like their Chinese neighbor to the north, the Khmer Empire was also known to employ ballista technology. Consequently, their team bonus increases the range of Scorpions. In addition, Khmer also possess a ballista-carrying unique unit named Ballista Elephant. Furthermore, the number of missiles fired by both Ballista Elephants and Scorpions can be increased with the Double Crossbow unique technology.
Khmer units speak their namesake, an Austroasiatic language (related to the language spoken by the Vietnamese) spoken as the official language of the modern Cambodia.
Along with the Malay, Khmer is one of the few major languages of mainland Southeast Asia that is non-tonal. It also shares similarities with Malay due to Indian and Sanskrit influence (e.g. Suosdey in Khmer and Swasti in Malay).

Khmer Houses can be compared to AtlanteanManors from Age of Mythology: The Titans; both can garrison Villagers. However, Manors support more population, soldiers can garrison inside and also cost some gold alongside wood.
They are the only civilization outside most Age of Empires III civilizations (Asian ones, however, need to construct Wonders) that can advance to the next Age without requirements. They also are the only civilization outside of the Age of Empires III civilizations and the Atlantean Citizens of Age of Mythology: The Titans that don't need dropsites for food produced by farms.
Until the Definitive Edition, Khmer Battle Elephants were the weakest against conversion as they did not have access to Faith.
The original Rise of the Rajas campaign scenario prologues and epilogues consistently mispronounce the name of the civilization. The Definitive Edition re-dub uses the proper pronunciation, better approximated by the spelling "K'mai."
The Khmer are the only civilization added in Rise of the Rajas that can train Hand Cannoneers. However, they are also the only Rajas civilization to miss out on the Bombard Cannon. They are also the only Rajas civilization that lack Supplies.
In the HD Edition, the Khmer were considered the worst civilization in 1v1 in the Arabia map, as they lacked significant economy bonuses, a confined tactic (only Battle Elephants and Scorpions are strong), lacking early-game economy and late-game trash units. However, after they received their new bonus for farmers, Khmer were considered an extremely powerful civilization in team games on closed maps like Arena, because they can gather enough resources to field overwhelming numbers of their powerful Battle Elephants, which can completely destroy entire enemy bases in a short time, being viewed as overpowered and unbalanced in team games.
During the beta, Khmer Villagers could use Houses as dropsites for resources.
Although the Khmer are one of the newest civilizations in Age of Empires II series, they have long been considered as the new potential addition by Ensemble Studio. During the development of The Conquerors, Khmer - along with Tibetans and Koreans - were considered as one of the new factions to represent the Far East region. Eventually, the developers picked Koreans because they were impressed with Turtle Ships and attracted by potential sales in South Korea.
Although the Khmer people had already settled in present-day Cambodia since the second millennium BC, larger polities would only emerge from the first century AD on. Along the Mekong river, the kingdom of Funan (68-550) and the kingdom of Chenla (550-802) profited greatly from trade and rice cultivation. However, it was their successor, the Khmer Empire (802-1431), that became the most powerful state during the Middle Ages in mainland Southeast Asia.
A century after the kingdom of Chenla had disintegrated, a local chief from Southeast Cambodia called Jayavarman II (770-834) reunited the different polities through military conquest and marriages. Following his successful expedition, Jayavarman crowned himself God King (Deva Raja) in 802. This ritual act, inspired by Indian Hinduism and local traditions, not only marked the birth of the Khmer empire, but also legitimized the Khmer kings as manifestations of the Hindu gods Shiva or Vishnu. Successive rulers used this power to intervene in many aspects of the Khmer society:
First, kings ordered largescale waterworks. Because monsoons greatly affected water levels, proper irrigation systems were essential for the widespread rice cultivation. At the same time, the government did not try to control production itself. Instead, local officials collected a levy from the traders in the marketplace, which was mainly run by women. Temples served as storage and were connected by an extensive network of roads, facilitating long-distance trade.
Second, Khmer rulers funded extensive building programs as they regularly moved their capital. This relocation was often accompanied by the construction of a new state temple that acted as the center of the city and a place for worshiping the king. Angkor, one of the largest pre-industrial urban areas, consisted of seven capital cities and housed over one thousand temples. In the early twelfth century, Suryavarman II (1113-1150) constructed the most famous state temple, Angkor Wat. Today, the temple is still considered the largest religious complex in the world, testifying to the engineering and architectural skills of the Khmer.
Finally, the king commanded the army. Between the ninth and fourteenth centuries, Khmer rulers continuously conducted military campaigns and conquered much of Southeast Asia. Their major enemies were the Siamese, the Vietnamese, and the Cham, who raided Angkor in 1177 and 1178. The Khmer had no standing army, but relied on appointed captains who were responsible for conscripting peasants in times of war. Aside from this large contingent of peasant infantry, the army deployed war elephants, sometimes mounted with ballistae.
The Khmer not only fought other civilizations. Because kings married multiple women, disputes between different lineages often resulted in civil wars. For example, after Suryavarman I (1002-1049) had claimed the throne, he fought eight years with other contenders. Political instability was inherent to the Khmer society. However, from the fourteenth century on, civil wars became more frequent as rulers were unable to deal with other, structural problems: rice cultivation declined due to a cooling of temperature, the conversion from Hinduism to Theravada Buddhism undermined the legitimacy of kings as divine ruler, and warfare with the Siamese resulted in a continuous loss of territory. Eventually, king Ponhea Yat (1405-1463) abandoned Angkor in 1431, marking the end of the great Khmer Empire.
