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.

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; and the Mon Khmer Culture is all scattered around the peninsula.


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, fort in Thanh Hoa may be destroyed. Also 7 transport ships could be sold or destroyed until colonies become available. It is advisable to declare war on Champa as soon as claim is finished, since Khmer or Lan Xang will also attack Champa as soon as they can. Build until your force limit, recruit a general from the nobility, declare war and stackwipe 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 next potential target depending the alliances that have formed.

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.
