Dai Viet is a mid-sized country in Southeast Asia. In 1444, they border Flag of Ming Ming, Flag of Champa Champa, and Flag of Lan Xang Lan Xang. 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]

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

Ever since the Chinese occupation the reverence of Confucius and the Confucian ideals run deep in our society. From the basic worship of Confucius in the folk religion of the commoners to the admiration and study of Neo-Confucian texts in our court.

Starting position[edit]

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. At the start of the game, the player will find themselves in a harder position than the other countries in the subcontinent. Dai Viet is actually the weakest of the Big Four of Southeast Asia (The other three being Flag of Lan Xang Lan Xang, Flag of Khmer Khmer and Flag of Ayutthaya Ayutthaya) because: it's Mahayana, so diplomacy is flawed for being heretic; has less development than all of them which leads to a starting smaller army.


Picking rivals at this point is pretty straight forward. Flag of Champa Champa, in the south, should always be the first objective. As it's the weakest and most isolated nation in the region. The other two most likely should be rivalling back enemies. Allying with a Burmese/Shan minor (Like Flag of Taungu Taungu, Flag of Mong Yang Mong Yang or Flag of Ava Ava) is a good idea as they can field a somewhat sizable army. Complete alliances with a regional power like Flag of Malacca Malacca (for naval superiority and to encircle Flag of Ayutthaya Ayutthaya) and Lan Xang/Khmer/Ayutthaya.

First steps[edit]

To save money, the fort in Thanh Hoa must be destroyed. 7 transport ships could be sold or destroyed until colonies become available. It is advisable to declare war on Champa as soon as the claim is finished since Khmer or Lan Xang will also attack Champa as soon as they can. Build until your force limit, declare war, and stack wipe Champa's weaker army. Try to blockade its capital with your fleet and wait. Once the war is over, take the provinces that isolate Champa from Khmer and Lan Xang. In the peace deal add humiliate rival and take as much money as possible. Khmer is the next potential target depending on the alliances that have formed. After defeat Champa, Ayutthaya almost attacks Khmer. When Ayutthaya having a war with Khmer, convert Hindu provinces and put out the Champa rebels. After the war with Khmer, if Ayutthaya won, attack the rest of Khmer and make Khmer become your vassal. If Khmer won (rate) attack them ( it would be harder so use mercenary ). When Khmer become your vassal, when Ayutthaya weaker ( when Khmer rebels revolt ), attack them with Reconquest (don't kill the rebels) If you won this war, Khmer would be a loyal vassal and it's time annex Khmer. The game is now easier. It could take 100 years to conquest the rest of Indochina and Malacca. I suggest using offensive ideas, defensive idea, and religious ideas. After a stronger, cancel tribute with Ming. It will make them angry. Allied with Korea and wait... Ming will attack and use your best general to defend. Ming will get huge attrition and let avoid from the battle (except they attack your fort). Use your army profession to get manpower and reduce your war exhaustion. When Ming weaker ( because of the revolt ) start counter-attack and NEVER accept their peace demand. Ming will be destroyed after this war when many new countries appeared. Make them become your tribute (or attack them if you want). Now you are the lord of Asian, use casus belli "take Mandate Heaven" but only take province from Ming. Ming very weak now ( they get more 50% shock damage because of low mandate) so it will be very easy

Idea groups[edit]

Dai Viet has an awesome combo of +1% attrition for enemies, +2% of tropical climate, +1% from siege. So picking up defensive ideas as one of the first three, will lead to a base of +5 monthly attrition. Exploration and Economic/Administrative should complete the first three.
