Threats of war are always imminent while trying to control most European nations in Europa Universalis V. There is a system of obtaining a Casus Belli, which justifies your means to start a war. But the process to obtain a Casus Belli is not straightforward; you need to go through several hurdles to get one. This guide details how to get the Casus Belli in Europa Universalis V.
Europa Universalis V – Casus Belli Explained
Casus Belli is a requirement to start a war with any nation, and creating a Casus Belli requires 20 Spy Networks. But first, you need to bring up your Parliament’s support to 50% or higher. That way, you get the option to fabricate a Casus Belli. To create a Casus Belli, right-click the nation you wish to attack, then select the Build Spy Network option. The longer your Spy Network stays within the nation, the higher the points you get under this influence. But this comes with the risk of losing your Diplomats. Per month, you will lose -0.10 Diplomats the longer you keep the Spy Network active.
Once you get 20 Spy Network points, you will automatically create a Casus Belli. These are clauses you could implement as a reason to start a war with the selected nation. To start a War, again right-click the nation, then select the Declare War option. On the new menu, select the Casus Belli in the bottom left corner to select the type of Casus Belli. This will directly influence the type of war and war goals that will be carried out. Once created, you have 4 years to implement it. Past that, the Casus Belli will expire, and you might have to redo the entire system.
Declaring War Without Casus Belli
It is possible to start a war without a Casus Belli, but it will come with consequences like national instability, loss of reputation, Antagonism, and even debt. This will tank your nation’s economy even further, which will hamper your progress in the long run. Plus, getting additional support from allies is dicey, and the chances of them not approving your actions are high.
If other nations get wind of your aggressive playstyle, there will be a risk of starting a coalition against you, which will not work in your favor. Hence why it is always recommended to use a Casus Belli when you get the chance, but if you are experienced and ready to take on the War, then it would be a great chance to test your skills without one.
Other Ways to Get Casus Belli
Events like the 100 Years’ War will automatically generate a Casus Belli to implement a war goal. Besides this, while working through your Parliament, check for conflicting policies or laws from other nations and use that as a base to create a Casus Belli. Also, as you keep playing the game, you might get auto-generated Casus Belli from missions, so keep an eye on those too.
