Still, for war to be grounded, you need Casus Belli, i.e. when you are a dependent country in a personal union or when your country is ruled by the Regency Council. You can declare a war nearly always, with small exceptions, e.g.

The first option in diplomacy is declaring a war or starting peace talks, if the war is already on. Otherwise, keeping your reserve diplomats is more important, and you should only break (and then immediately remake) royal marriages when you get to 6 diplomats.You can use diplomacy to wage wars without rolling out cannons War and peace Thus, if you can regain stability very fast - one point in the time it takes you to generate two diplomats - then it is better to break the royal marriage as soon as you get to 1 diplomat.

But you can still break a royal marriage with one. One twist is induced by the fact that breaking a royal marriage takes two diplomats, if you have them, not just one. But other than that, you can get relations all the way up to +200 if you have the time. Often you will need to pay money to bribe the other country through the "gap" in relations, from -5 to +25, where royal marriages don't work. Generally, high relations are not so important relative to technological goals that you should channel your monthly income into stability if you cannot raise stability a point per year or so without any monthly income, then you probably should not be using this tactic. For a particular target country, assuming you can make royal marriages, keep breaking them and then remaking them as fast as you get diplomats and/or recover stability.

your country has a good production of diplomatsĭoing it is fairly straightforward.your country has a relatively high level of direct investment into stability, i.e., your monarch has good administration, and/or you've got one or more fine arts academies.your country has a relatively low stability cost (i.e., is small).In general, making and breaking RMs is a good idea when the following conditions hold: "Cheap" here is in terms of treasury money the method is expensive in stability and diplomats, cheap in money. Making and breaking royal marriages is a method by which a player can very cheaply raise relations with another country or countries.
