Dai Viet is a mid-sized country in Southeast Asia. In 1444, they border Flag of Ming Ming, Flag of Champa Champa, Flag of Muan Phuang Muan Phuang (who they are guaranteeing at start) and Flag of Lan Xang Lan Xang (who also guarantees Muan Phuang). If they can maintain their independence from Ming they have the potential to expand greatly in the region and colonize the rich islands around them.

Vietnamese minor states[edit | edit source]

The kingdoms of Flag of Annam Annam and Flag of Tonkin Tonkin break off from Dai Viet in later historical starts, starting from 1527.

Strategy[edit | edit source]

Starting Position[edit | edit source]

Dai Viet revolves around two major strategies: The first, annexing neighbours while improving its military quality; and the other, colonizing and expanding into the Pacific islands while slowly doing it in the mainland. Despite starting with less development than any of the other Big Four (Itself, Flag of Lan Xang Lan Xang, Flag of Khmer Khmer and Flag of Ayutthaya Ayutthaya), Dai Viet's unique geographical position on the edge of Indochina lets it pinch Lan Xang and Khmer between itself and the strongest power, Ayutthaya, allowing the player to succeed in taking out those two nations and dealing with Ayutthaya next.

Additionally, Dai Viet starts with the Nobility Estate having the "Control of the Army" Privilege. This gives +1 yearly army tradition, but prevents you from progressing your missions. It is difficult to remove because it gives 30% influence and 0% loyalty. There is a strategy to remove this very quickly (within three days of start), but is not recommended for new players due to the very low percentage of crown land it leaves you at. Summon the diet and restart if you get a nobility agenda that cannot be completed before the month tick. The best one is the agenda for gaining allies. Then give either the Merchant Guilds or the Monasteries their "Primacy of" privilege for an additional mana point each month. This changes the ratio of land that each estate holds. Then sell land. You will have gained 25% loyalty (50%->75%) from summoning the diet, selling land, and completing an agenda. However, the nobility's influence will have also risen from gaining land you sold them and summoning the diet. However, because you changed the ratio before selling, it's only by about 4% after the 5% from the diet; a total of 9% (65%->74%). This gives you just enough loyalty to revoke the "Control of the Army" Privilege within three days of game start if you get the right agenda.

Diplomacy[edit | edit source]

Picking rivals at this point is pretty straight forward. Flag of Champa Champa, in the south, should always be the first objective, as it is the weakest and most isolated nation in the region. The other two most likely should be rivalling back enemies (usually Flag of Khmer Khmer and Flag of Lan Xang Lan Xang). Show interested in some provinces in Lan Xang and Ally with Flag of Ayutthaya Ayutthaya and Flag of Lan Na Lan Na so you can join their war early game against Lan Xang and take some lands since Dai Viet is crippled with regency early game in 1.31. Although it is not necessary since Dai Viet is strong enough on its own to dissuade AI attackers on traditional difficulties. Flag of Malacca Malacca is one of the best potential allies as they can be used to block in and flank Flag of Ayutthaya Ayutthaya, the strongest nation in the region who you will have to eventually face.

Early Game[edit | edit source]

Dai Viet begins with two forts, but it is recommended to destroy the fort in Thanh Hoa to save money. The fort on the capital should not be destroyed because having a Level 3 fort can be somewhat useful against AI.

In 1.31 update, Dai Viet cannot attack in the first 10 years of the game due to regency: Nguyen Thi Anh (4/4/3). Players can wait till the regency end but the not recommended because Le Bang Co (1/1/2) has a mediocre stat. Meanwhile, Flag of Dai Viet Dai Viet has event "A Moment of Splendor" that makes Nguyen Thi Anh with her improved stat become the queen of the country. To activate this event, the stability of Flag of Dai Viet Dai Viet have to be +1 and the year should be before 1459.

Immediately begin fabricating claims on Flag of Champa Champa, as they are the easiest route of expansion for Dai Viet. You can declare war on Champa as soon as the claim is finished or when the regency end. You can also allied with one of the Tay Nguyen tribes if Flag of Champa Champa declare war on them and the regency is still going. During the war with Champa, you can use your starting navy to blockade the Level 3 fort on their capital to quicken the siege. It is also recommended to hire the cheap Free Company mercenaries, as they cost less than normal troops and do not use your manpower. Focus on stackwiping Champa's army first, as you then want to siege all of their provinces to prevent Flag of Khmer Khmer from taking land for themselves. Use your starting transport ships to move troops past Champa's fort. Once Champa is annexed, it is recommended to simply culture convert Cham culture once it is possible, as the culture is too small to justify taking up an entire culture slot that could be better used on large cultures in Burma and Maritime Southeast Asia. If player has Leviathan DLC, this is a must to finish the mission and get free claims in Khmer. Dai Viet's starting idea is very useful for this, as well as exploiting tax development from Cham provinces. Remember that adjacency is important for making culture conversion cheap.

The next target is most likely Flag of Khmer Khmer, who is usually attacked by Flag of Ayutthaya Ayutthaya, and Flag of Lan Xang Lan Xang, who often suffers the same fate.

Early on, Dai Viet will likely obtain the event Confucian Heritage which will give the player the option to convert to Confucianism Confucian or stay Mahayana.png Mahayana. Before 1.31 Leviathan, Confucianism Confucian is one of the worst religions in the game in a normal playthrough. This is because Confucianism Confucian and Harmonization bonuses are mediocre at best and Confucians are unable to convert the religion of provinces properly without tanking a large amount of Harmony, causing unrest in the early game, the part of the game where rebels are most dangerous. And you cannot convert the culture of provinces with a harmonized religion, essentially locking you out of doing so and ironically creating more unrest. But this is not the case in 1.31, Flag of Dai Viet Dai Viet can still convert culture Cham after harmonized Hindu religion. And with additions of Confucianism Confucian monuments in Hue and China, Confucian choice in 1.31 Leviathan is better for conquer Ming mission route.

Culture and Religious Routes[edit | edit source]

In 1.31, Vietnamese is grouped with Chinese culture in the begining. This is a good starting point for conquering Flag of Ming Ming later on in the game.

Religiously, Mahayana.png Mahayana is one of the weakest religions in the game. Idea cost.png -5.0% Idea Cost is a very mediocre modifier, so it is really like this religion only has Discipline.png +5.0% Discipline and Diplomatic reputation.png +2.00 Diplomatic Reputation. Therefore, swapping religions is a great idea that will strengthen your Vietnam.

Dai Viet can immediately swap to Vajrayana.png Vajrayana at the beginning of the game for the cost of Yearly prestige.png -100 Prestige and Stability.png 1 Stability. This will give Vajrayana's base bonus of Morale of armies.png +5.0% Morale of Armies, which is great, unlike Mahayana.png Mahayana's base Idea cost.png Idea Cost. Theravada.png Theravada can also be swapped into, but its base modifier, Advisor cost.png -10.0% Advisor Cost, is not that good compared to Vajrayana's Morale of armies.png Morale of Armies, especially since every nation can already gain cheap advisors with the estate privileges. In addition, swapping to Theravada.png Theravada will remove one of Mahayana.png Mahayana's perks which is preserved with Vajrayana.png Vajrayana: its religious isolation, allowing you to utilize the Deus Vult Casus Belli from Religious Ideas as well as the Clergy privilege Expansionist Zealotry, which gives another Morale of armies.png +5.0% Morale of Armies.

Another great religion to swap to is Hinduism Hindu, although this will lock you out of using the Mandate CBs on Flag of Ming Ming. Hinduism Hindu is quite a bit stronger than Vajrayana since it has many good modifiers and versatility, especially with States General or Republic government. However, Sunni Islam Sunni, accessible in Borneo or the Malaya peninsula, is much stronger and by far, the best religion to access disregarding the Mandate CB.

As mentioned, Dai Viet gets an event early on that gives the option of converting to Confucianism Confucian with Mahayana.png Mahayana already harmonized. This could make the conquest of China is easier. However, it is more worth it to simply convert China to another religion long term, outside of big blobbing games, of which Confucian is not even the best religion. Sunni is easily accessible and allows you to tolerate all heathens instantly while providing far stronger bonuses.

Achievements[edit | edit source]
