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 considered to be one of the most unconventional civilizations because of their civilization bonus, the ability to advance to the next age or build other buildings without requirements. This makes the Khmer very flexible when it comes to their build orders and opening up to unconventional and unpredictable strategies. At the same time, said civilization bonus can be seen as a double-edged sword; it can backfire on the player if used inappropriately. As such, the Khmer are designed for experienced players who can maximize the use of the civilization bonus.
As noted, the Khmer are a siege-focused civilization with emphasis on Scorpions and Battle Elephants, which is also reflected in their unique unit, the Ballista Elephant. Subsequent balance patches in the Definitive Edition, however, push the Khmer more into a "jack of all trades" civilization, with infantry as their only noticeable weakness in their tech tree (which is fitting for a civilization that does not need pre-requisites to advance to the next age or build any building).
The Khmer are classified as an elephant and siege civilization, and they really shine in their advertised departments. Their Battle Elephants are particularly dangerous as they get a notable speed boost which, along with Husbandry, effectively addresses their greatest weakness which is the low speed (although they are still not fast enough to escape Halberdiers). Additionally, they get +3 attack out of Tusk Swords which lifts their attack to levels only the Elite War Elephant sits in.
They get +1 range from their team bonus and another +1 from Siege Engineers for a total of 9 - enough to outrange Arbalesters, and they get a second bolt fired simultaneously (from Double Crossbow) which greatly increases their damage output. The Ballista Elephant also deserves a mention here as it broadens the versatility in their siege department, but it often struggles to be effective unless used in mass numbers. Their navy is average at best, as they lack the Heavy Demolition Ship and Shipwright, but their Monks leave much to be desired. Their defensive structures are average, and their economy is lacking as well without Two-Man Saw and Guilds, but their farmers can drop off food directly to the player's stockpile.
The Khmer have a campaign devoted to their civilization: Suryavarman I. They also appear in:
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).

The bottom left and right of the navigation bar in the user interface display an image of human face based from the statues found in Bayon Temple depicting the face of Avalokiteśvara.
This image is also used as the civilization icon of the Khmer in the Definitive Edition.
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 and unbalanced civilization in team games, especially on closed maps like Arena, because with the new farm bonus (which did not have a slower workrate, meaning Khmer farmers were too effective for booming and advance to next age much faster than other civilizations), in conjunction with advancing ages without buildings and no building requirement to access others, plus their formerly much faster Battle Elephants (In the Castle Age, Khmer Battle Elephants could outrun foot archers without Husbandry, giving a major advantage for their team), made them able to field overwhelming numbers of them, which could completely destroy enemy bases in a short time. The Khmer also have a wide tech tree with good options for archers, cavalry, siege, and navy. With the farm bonus, this made them the best civilization on various maps. This possibly explains the several nerfs to Battle Elephants (including reducing the Khmer Battle Elephant's speed bonus from 15% to 10%), the removal of Bombard Cannons to give them a weakness against Onagers and Halberdiers, the slower workrate of their farmers, and the increased cost of their Castle Age unique technology Tusk Swords.
During the beta, Khmer Villagers could use Houses as dropsites for resources, mostly due to a bug.
The Khmer are the only non-India civilization with access to more than one type of elephant unit.
Behind the scenes
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.
