Jayavarman VII of the Khmer brings water and sends martyrs in Civilization VI

Civilization VI's third expansion, Gathering Storm recently released and has added a handful of new civilizations and leaders. I am hoping to write a strategy for each of them, but I also want to continue to write guides for the civilizations that were already in the game. I put up a poll on my Patreon page for my patrons to vote on which civ(s) they would like to see. The three top vote-getters (from all the three people who voted) were Khmer, Aztec, and Norway. It's been a while since I've done a strategy for a religion-oriented civ, so I thought I'd do a strategy for Jayavarman VII of the Khmer. The Khmer were present as a playable civilization in Civilization IV's Beyond the Sword expansion, but they were not present in Civilization V. They appeared as a DLC civ prior to Rise & Fall's release, but this strategy should work for players of the new Gathering Storm expansion as well.

The city of Angkor, the capital of the Angkor Empire (also called the Khmer Empire), is believed to be the largest pre-industrial urban center in the world, stretching for roughly 400 square miles and housing roughly 0.1% of the entire global population at its zenith. This empire controlled most of mainland southeast Asia from the ninth century CE to the 15th century CE, reaching its zenith between the 11th and 13th centuries. Many impressive ruins still stand in the site of Angkor, and many have been restored by local archaeological organizations and UNESCO, including the impressive Angkor Wat, the largest single religious monument in the world. Satellite imagery has also revealed an intricate network of irrigation channels which were likely used to manage the regions unpredictable monsoons, as well as to support the population.

Around 1150 CE, the kingdom of Angkor was invaded by the neighboring Cham empires, who succeeded at toppling the capital. General Mahaparamasaugata (believed to already be over the age of 60) lead a successful campaign to push the Cham out of the Khmer capital, and he ascended to the throne in order to continue the war and conquer much of the Champa territory. He relocated the capital to Angkor Thom, where large monuments were constructed in his honor, including the temple of Bayon. He went on to re-unify the empire, building a network of roads connecting every major town, complete with rest-houses every 9 miles and hospitals for travelers. He reigned successfully until his death at the impressively-ripe old age 97 or 98, and is regarded as the last great king of Cambodia. He was posthumously re-named Jayavarman VII, after a line of Cambodia's greatest kings.

DISCLAIMER:
Civilization VI is still a "living game". Strategies for the game (and for specific leaders and civs) may change as Firaxis applies balance patches, introduces new features, or expands the game through further DLC or expansion packs, or as the Civ community discovers new strategies or exploits. As such, the following strategy guide may change from time to time. I will try to keep it up-to-date, and will make notations whenever changes are made. I'll also post links in the official 2K forums and CivFanatics, where I'll also report any changes made. If possible and practical, I will try to retain the original content of the strategy for posterity.

I welcome any feedback or suggestions that readers wish to offer. Feel free to post on the linked forums, or by posting a comment at the bottom of the page.

This guide is up to date as of the release of the Gathering Storm expansion (ver. 1.0.0.314) (Antarctic Late Summer Patch, April 2019)

Khmer is a strong religious civ who gets extra food from Holy Sites, and extra faith from Aqueducts, as well as other bonuses to food and amenity. It can build and support large populations in its cities, and gets relics from its missionaries and apostles much more frequently, which can contribute to a culture victory.
