Today we’ll talk about the tools you have regarding vassals, marches and lesser union partners.
Placate Local Rulers
This can be done on both vassals and marches, and lets you pay prestige (if you have positive prestige), to reduce the liberty desire of that subject by 10%.
Embargo Rivals
This is a toggle you can put on any subject. If it is on they will embargo all your rivals as quickly as their diplomats can travel. However, this increases their liberty desire by 5% while active.
Place Relative on Throne
This can only be done on vassals, and only when they have a regency. You can replace the regency with a ruler from your own dynasty.
Enforce Religion
This can only be done on vassals, unions and marches. This is possible if the subject is in your religious group, have less than 50% of Liberty Desire, and you have positive relations. Of course, this increases Liberty Desire by 50%, so its something you have to evaluate when it is desirable to do.
Scutage
This is a toggle that can be set to on or off on a vassal. When it is on, they will not be called into wars, unless declared war upon. However, they will provide 50% more of its income to you.
Subsidize Armies
This is a toggle in marches, where if on, you will send up to 10% of your manpower to them each month, to fill up their manpower pool.
Fortify March
This allows you to build or upgrade a fort in a march, where you as overlord fronts the build costs.
Enforce Culture
This is the option if you got some diplomatic power to burn. You can swap the primary culture of a lesser union partner to your culture for a power cost, but this is only doable if they are below 50% liberty desire and it will increase it by 50% as well.
Siphon Income
Unions usually do not provide money to their overlord, but history is full of rulers who took from one part of their realm to provide for another. This action lets you take 50% of a lesser union partners yearly income if you have positive relations. It will increase liberty desire by 10% but also reduce relations rather dramatically.
Support Loyalists
Unions don’t have any local ruler that needs to be placated, so instead you have a toggle where you spend 10% of their monthly income each month, while reducing liberty desire by 20% as long as its active.
