Where Can Diplomatic Play Be Used?

It is important to keep in mind that you can not even use Diplomatic Play against every country. Rather, it can only be used against certain countries that you have marked an interest in. Also, the overall ranking and prestige of your country decide the number of countries you can declare interest in.

The giant country you are, the wide will your interests gets. Thus, the number of countries that you can use Diplomatic Play against increases with your ranking and prestige.

Escalation and Maneuvers Phase

After getting done with the Diplomatic Play, the next step towards declaring war in Victoria 3 is the Escalation and Maneuvers phase. Then, right after the selection of the Diplomatic Play in Victoria 3, war requires you to undergo two more steps.

Escalation Phase

Escalation is the phase during which you decide the objectives you plan to achieve with war. The players can add more goals to the war from the available ones. The goals to choose or available depending on the target country and the Diplomatic Play you opted for.

Maneuvers Phase

After defining the objectives of the war, the next task you are put against is to acquire maximum support from other countries. This phase is the Diplomatic Maneuvers and looking for countries with similar interests in the region to join your forces.

It is the longest phase towards waging war against your target country in Victoria 3. In this phase, you use the Sway tab to sway countries to your support. Go to the Sway tab and click on the country and click on the green thumbs-up icon there.

If the country accepts your proposal, it’ll join you in your war with its forces. At the same time, some countries will join you without offering them anything in return based on their position in the conflict and region. But, the others can be pursued by offering Obligations to them. The obligation must be chosen smartly as the country may oblige you to join their wars, and that can wreck you if you are already struggling.

You can also Sway the countries who have joined the opponent’s forces and make them neutral. They can’t be made to join you in the war but it’s better to have lesser enemies.

Countdown Phase 

This phase starts after the Maneuvers phase has been passed. There’s a countdown and both of the countries are given a chance to Back Down and surrender without war. But it’s likely that AIs will fall on their knees if you have a huge advantage over the statics and the situation.

If one country has a clear advantage over the other, it should draw back and this can help them not face more destruction, blood loss, and Economic destruction. But if both countries don’t fall back, then start the war in Victoria 3. Then, you can achieve your goals with the use of force.

Tips To Lead Towards Victoria 3 Wars

The strategy must be opted to win a war and here’s how you can do that

Generals and Battalions

Generals and Battalions are the key to warfare in Victoria 3 and decide how you perform in the wars. More generals with expertise will help you move forward more steadily and strategically. But this must be kept in mind that generals and their promotion can greatly affect the political situation of the country. The more the generals are ranked higher, the more the soldiers are under their command.

Generals do have certain abilities and thus should be positioned in such a way as to take maximum advantage of their abilities and expertise. For instance, a general with the ability of an Expert Offensive Planner can be deployed in a region where you need to practice more offensive tactics.

Army Size

It’s no surprise that having a large number of troops is going to be very helpful in the war. So, if your army quality is just average, but you have a large number of troops to fight for you, you’ll excel. It can be done by constructing more and more barracks and inducting civilians into the army. Inducting civilians into the army forcefully might affect happiness but if the war is that important to compromise happiness, go for it.

Diplomatic Standing

Another fact that plays a significant role in winning a war is your diplomatic standing. Diplomatic standing hugely dictates the support of other countries. Thus, if your diplomatic standing aligns with some other country, it’ll surely join forces with you in the war. This will let you have more support in terms of soldiers also.

But having the support of AI allies might not be that beneficial all the time. Every country has its own issues going, and they can’t just ignore everything to support you in your war.

Handling Of Country Affairs

Having said that, you should not expect your allies to help you blindly in the war; this is also to be followed by you. So, players must not forget about the handling of their country during a war. This means you must run your country simultaneously with the war.
