The Kingdom of Ayutthaya was the major power in Southeast Asia in the 14th and 15th centuries. Based in the capital of Ayutthaya on the Chao Phraya River (Central Thailand area), this decentralized Tai kingdom managed to exercise hegemony over the region for many years. Trade rivalry with Flag of Malacca Malacca and constant wars with neighboring Burman countries and the declining Flag of Khmer Khmer Empire typified its history.

Ayutthaya starts as a tributary of Flag of Ming Ming which is the Emperor of China in 1444. They have two vassals, Flag of Sukhothai Sukhothai in the north and Flag of Ligor Ligor in the south.

As Leviathan.png Leviathan Expansion has updated Southeast Asia, Ayutthaya became an excellent option to play as a semi-beginner. This country is not in Europe and is not a major, but can expand without many difficulties as it is stronger than all of its neighbours.

Missions[edit | edit source]

Main article: Siamese missions

Ayutthayan missions are focused around conquering Indochina and Burma regions, alongside rising as a trade powerhouse. Besides, Ayutthaya should vanquish internal challenges to form Flag of Siam Siam and turn their namesake capital the envy of the world. Finally, if Ayutthaya is powerful and bold enough, this country may claim the ultimate prize: the Mandate of Heaven!

Events[edit | edit source]

Ayutthayan events are mainly focused on national reforms, integration of Flag of Sukhothai Sukhothai and struggling for the formation of Flag of Siam Siam.

Strategy[edit | edit source]

Strategy The below is one of many player suggested strategies for Ayutthaya. Bear in mind, due to the dynamic nature of the game, it may unfold differently for other players.

Early game[edit | edit source]

Ayutthaya starts off in a very good situation. The country is a tributary nation of Flag of Ming Ming, which means it will have to give yearly tributes in exchange for China's protection from outside invaders. Consequently, Ayutthaya will likely never have to worry about surprise invasions from India or the Europeans. However, tributaries may war among themselves without provoking the wrath of China, so the kingdoms of Burma and Indochina are free to engage in wars of conquest without external interference. Ayutthaya must take advantage of this to secure regional dominance and grow in power.

Even without taking its vassals into account, Ayutthaya is the strongest kingdom in Southeast Asia, which makes it the prime contender for uniting Indochina. Another significant starting advantage is the fact that Ayutthaya has cores on its subjects, so it can seize territory immediately and, after ten years, can annex the vassals for no cost. On the downside, Ayutthaya has a weak starting ruler and its main trade node, Siam, is fairly poor. Setting up a solid trading network will require lots of conquest and investment in naval supremacy.

Ayutthaya's natural enemy is Flag of Khmer Khmer. Historically, Khmer was the major power of the region before Ayutthaya overtook it a few years before the start of the EUIV era. Ayutthaya has one of Khmer's cores, which will almost always lead to an immediate rivalry, but Khmer is the weaker of the two and should not be a huge problem. It holds the other trade power province of the Siam node, so conquering Khmer in two swift early wars will significantly boost Ayutthaya's income. Other strong powers are Flag of Lan Xang Lan Xang to the North-East and Flag of Dai Viet Dai Viet even further to the North-East. The other neighbours are smaller states, Flag of Pegu Pegu to the West and Flag of Lan Na Lan Na to the North. Besides that, Ayutthaya is surrounded by its vassals Flag of Sukhothai Sukhothai and Flag of Ligor Ligor. The only states relatively even in strength are Flag of Malacca Malacca and Flag of Bengal Bengal but Ayutthaya has time to expand and become stronger than them before any confrontation begins.

Ayutthaya can defeat any individual neighbour alone, but if several of them ally, it is probably safer to ally some other states nearby. Dai Viet or Lan Xang will provide the most help, especially to crush the other, but having one or two of any of the states in Indochina as an ally will almost guarantee easy victories against any neighbour no matter how many allies they have.

Manpower will be a critical issue in the earlier stages of the game. The tropical terrain of Southeast Asia will significantly reduce provincial supply limits, and Ayutthaya does not have enough manpower to replace catastrophic losses easily. The player should take care not to lose too many troops to attrition. Ayutthaya's national ideas reduce the high maintenance costs of mercenaries, so hiring them can help save on manpower.

Once the other kingdoms in Indochina have been annexed or vassalized, the early game is over and the time for Ayutthaya's expansion into the greater world will have arrived.

The White Elephant: After becoming the unquestioned main power by defeating Khmer and other nearby powers, the player is probably close to getting the achievement The White Elephant. Bear in mind that the achievement's text is inaccurate; both Indochina and Burma must be controlled for it to fire. Chittagong, one of the required provinces in Burma, is owned by Flag of Bengal Bengal at the start of the game. Bengal is very likely to become a significant power as time goes on, so a player seeking the achievement should try to take the province before Bengal grows too strong. Remember also that Ming may step in and take one or two provinces in Indochina or Burma. If that happens, the player will have no choice but to eventually confront Ming.

Potential other goals[edit | edit source]

Indonesia[edit | edit source]

A natural expansion path for Ayutthaya that almost or totally united Indochina and Burma would be to try to set up a trade network more efficient than what you have. An extremely good node to control is thus Malacca, far superior to Siam and also the only node towards which Siam flows, so you don't waste your early game money. That requires you to conquer many nations, many of them stronger than what you were used to, like Flag of Malacca Malacca or Flag of Brunei Brunei. You should be in a position where you are still stronger than them, but getting a good navy will be needed to control the area, full of islands. Allying a state like Flag of Pasai Pasai or Flag of Majapahit Majapahit can also help getting an early edge if the player choses to expand in that direction. From there, you can decide to smooth up your borders and play a colonial/trade oriented game around the Spice Islands with idea groups like Exploration, Expansion and Trade. Either Religious or Humanist is probably needed to deal with the numerous Sunni land you will conquer.

India[edit | edit source]

Another road is to go towards India. There are many strong nations there but also a lot of riches. A more aggressive player could decide to conquer all of India or the eastern part of it, which proves to be more of a challenge but is still relatively easy, considering Ayutthaya has easier expansion paths than the other strong Indian powers. The player should still be careful if they are blocked by an alliance of two or three strong Indian powers and get alliances of their own or wait for good opportunities. Good idea groups are everything useful for conquest, like Administrative and Influence, and several military groups, especially Offensive. Buddhist nations are eligible to form Bharat, so by cultureshifting to Bengalese (for instance), you can form the state relatively early and get free claims on all of India.

China[edit | edit source]

The last objective and the hardest one can be pursued immediately or after the others, depending on the challenge you want to face. Ayutthaya follows an eastern religion, which means they can claim the Mandate of Heaven from Flag of Ming Ming with the proper DLC. Even without it, Ming is the obvious power of the area, and defeating them can be a nice endgoal for a campaign. This requires either massive expansion towards Indonesia or India to get a strong powerbase, or a careful plan and many allies, as Ming is extremely strong. Ayutthaya is still one of the non-horde countries with the most potential to overthrow Ming and create an alternate history in which the Imperial power shifted to the South. For this, stacking military ideas and strong policies is needed. Defensive is an obvious choice to win battles thanks to the morale boost, as is Quantity to overcome their massive numbers.
