The obvious thing to do is make Austria, Savoy, or Tuscany your rival and wait for the Enemy Of My Enemy bonus to build up.

Can you use military access on a union partner?
I think you can get "defended allied territory" for fighting rebels (+10).
Fight a war with their rival and take a province (+15).
Get into a war together and when it's over you should get +10 for "fought to the end".

Seems like PU should give a bonus similar to vassal given that it prevents you from getting alliance & RM bonuses. Should get at least the equivalent of same dynasty + RM bonuses.
 
At a guess, you haven't explored the sea zone that its port opens onto.

Hungary is his PU-minor, so unfortunately that doesn't work.

Qoff: I covered this in some detail, in this post: How to further boost relations with PU-minor: via war.

Basically, you're going to have to go to war against Morocco, Poland, Savoy or Denmark - Hungary's Enemies.

If at all possible, you want it to be Savoy, because they are also Hungary's Rival.

That gives you an instant +10 "Declared War on Enemy" bonus, then there is another +20 available for Defender Our Territory and Liberated Our Province, totalling +30. Finally, if you annex one of Savoy's provinces, you can get another +10 for Conquered Rival Province. That one of course only applies if you DOW Savoy, who is the only nation who is both a Rival and an Enemy.

You need a total of +25 once you've maxed out Improve Relations, so you do need three out of four of those bonuses. So you have to do a bit of work to get in the right war, and have the right things happen in that war. See my post for more details.

In your case, the best strategy is to DOW Savoy, wait until they (or an ally) has some troops on Hungary's soil, then go kill them. Then win the war and annex one Savoy province. That will give you your +30. Note that the +10 Declared War on Enemy decays at -1 a year, from the start of the war; so don't let the war go on more than 5 years!

EDIT: Oh, ninja'd by jdrou!

No

Fight a war with their rival and take a province (+15).

That's great, I thought it was +10

Get into a war together and when it's over you should get +10 for "fought to the end".

Awesome, I forgot about that one too - it definitely applies to PU-minors? I'm sure it does.

So in that case, there's a total of +70 available from all this:
  • Declared War On Enemy, +10
  • Conquered Rival Province, +15
  • Defended Our Territory, +10
  • Liberated Our Province, +25
  • Fought To The End, +10
He only needs +25, so I wouldn't bother with Liberated Our Province which requires letting the enemy complete a siege against him.

And if he can't fight Savoy for some reason, he could DOW one of the other Enemies who isn't a Rival, foregoing Conquered Rival Province, but still getting +30 in total.

(I've also now edited my earlier post, that I linked to above, so it can be an accurate reference point for future; merging in the extra bonus jdrou mentioned, and fixing Conquered Rival to +15.)

EDIT 2: I just checked opinion_modifiers to double check the actual values. Liberated Our Province is actually +25! The others were all correct.

Regarding the above, I have now both updated my original post with the latest findings, and bumped the thread with a new summary that lists all the bonuses, their conditions, and their decay time.

It also summarises the totals you can get depending on whether you DOW an Enemy+Rival, Enemy, Rival, or none of those.

See here for details: Summary of subject nation relations modifiers obtainable via war.
 
I don't understand the PU CB it does not seem to appear.
I start a game as Austria, day 1 RM Bohemia, wait one month, Claim Throne.
Wait another month till i can declare war, no options to declare war with the PU goal. The only option is to "Revoke Electorate".
So i declared war anyways, got 85% warscore, still no option to force PU in the peace options.
Same thing with Hungary, although normally you get an event to Reform the PU with them so i just wait for that to happen right?

I also have the same problem in my England game, Claim Throne against Portugal (same dynasty). Nothing happens for a while and i loose the claim or i declare war but still no PU option to start or end war.
 
According to the Wiki every catholic country can DoW the target of a crusade. I currently play France in 1515, I'm 100% catholic, Papal controller with 5 out of 7 cardinals and launched a crusade against the Ottomans. Only I cannot use the CB... was it changed so I now need Deus Vult?

Both the Excommunication and Crusade CBs only apply when you are a neighbour of the target. So you must have at least one province that borders one province of the target. This does not need to be cored, and a colony counts.

As soon as you get such a border (or at month-end), the CB will automatically be granted and you'll be notified via a pop-up.

(In fact the majority of CBs have a neighbouring requirement.)
 
Ah, thank you. So the Wiki is incorrect there?
Holy War

Used by countries with "Deus Vult" from the Religous ideas group against neighboring heathens (Catholics may also use this CB against the crusade target, without "Deus Vult").
War goal is to win at least 80% of the battles.
Full Annexation, Conquest of Claims
75% Aggressive Expansion
125% Prestige
100% Cost
This is pretty dumn in regards to a Crusade where is was an extreme exception to the rule that a neighbour would participate and practically completely devaluates crusades... but then again, this ain't CK2 ^^

Unless you were specifically notified that you got a CB, via a pop-up, you don't have it: so don't go to DOW unless you got such a pop-up, and/or the CB is listed correctly on the DOW screen.

When you do or don't get a PU or the chance to force a PU is somewhat complex and obscure.

Please read this thread for quite a lot of discussion on the subject: Stupid doubt with PU.

Read the whole thread, but in particular this post and the ones following it.

In your England->Portugal case. You had same dynasty, that's good. Did they have no heir? You won't get any PU or CB if they have a weak heir, they must have no heir at all. So it's not enough for them just to appear on the Disputed Succession flag, and for Claim Throne to be clickable.

If they had no heir, and were of your dynasty, then I would have expected you to be in an automatic PU situation without Claim Throne, and for Claim Throne to give you the CB. One possibility - check if Portugal has any PU subjects of its own. If they do, that will definitely block it, and you need to wait until they integrate that PU-minor (and hope that that happens before they get an heir.)

Most importantly, what did their Monarchy tooltip say would happen when their Monarch died? Did it say that they would go into PU with a different nation? Or that "A Noble from House <your house> will succeed", or something else?

If it was a PU with a different nation, then you might need to get more prestige than that other nation. Although we've had reports that if that other nation is a Lucky Nation, like Austria, then there might be nothing you can do and Austria will just get the PU; though I can't remember what happens when you Claim Throne in that situation, possibly that overrides their auto PU.

Anyway, first of all read that thread I linked, then come back with details on what their monarchy tooltip says. Unless they had an heir, in which case all bets are off anyway.

Used by countries with "Deus Vult" from the Religous ideas group against neighboring heathens (Catholics may also use this CB against the crusade target, without "Deus Vult").

It's not greatly worded, but it does have the info in there - it says "against neighbouring heathens". It would have been clearer if it had said explicitly that that neighbouring limitation also applied to Catholics with the Crusade CB. The Crusade CB is also 'neighbouring heathens [against whom a Crusade has been declared]' so I guess they didn't see the need to re-state it. Much of the Wiki is written by non-native English speakers.

This is pretty dumn in regards to a Crusade where is was an extreme exception to the rule that a neighbour would participate and practically completely devaluates crusades... but then again, this ain't CK2 ^^

I thought the same when I first encountered it, but on reflection I feel it's necessary as otherwise it would be overpowered.

Note also that, in the case of Crusades, there's more to it than just the CB. Any Catholic nation who is at war with the Crusade target, for any reason, will get the Crusade bonuses.

So it's still worth it to declare a Crusade even if you don't have a border and can't get a border. Just find some other way to DOW them - like lending them money for them to renege on, or just taking the stab-hit of a no-CB DOW - and then enjoy the lovely bonuses for the duration of the war.

Ideally, wait until you're about to go to war against a really tough opponent, then declare a Crusade against any crappy heathen nation that you border or can DOW. Declare war on your Crusade target, then declare war on the main opponent, and enjoy the bonuses for both wars; the Morale and Manpower bonuses are especially helpful.
 
I half agree. All of Europe dogpiling on the Ottomans or Morocco risking nothin but the troops they send does seem excessive. But to represent historical crusades, maybe there should be different limits. Like reduced or no manpower refreshing of overseas troops or the requirement that you need Deus Vult for DoWing non-neighbouring Crusade targets?

I've fixed it to avoid future confusion :)

  • Used by countries with "Deus Vult" from the Religous ideas group against neighboring heathens.
  • Catholics may also use this CB against a neighboring Crusade target, without "Deus Vult".
    • When a Crusade is declared by the Papal Controller, the CB will be automatically given to all Catholics who have any border with the target.
    • The CB is added immediately for Catholics who already have a border; Catholics that gain such a border later, while the Crusade is still in force, will receive the CB at end-of-month.
 
Bumping my question (sorry, but my time is running out).

What counts as "coastal" province? Is an island considered a coastal province? The province in the picture below is within my colonial range and it looks like it's on the coast of Africa but I can't colonize it.

Someone already answered above - it's because you have not explored the Terra Incognito (TI) immediately below Whydah. You have not explored the sea province that contains the port for Whydah, therefore it's not a port/coastal province for you!

Reveal that TI if you can and it will work.
 
@Radrussian: The problem is, that the sea that the province's coast is located in is not discovered yet. Therefore you have no "route"

@TheBloke: Do you know where such things can be suggested?
 
So I just ran into a problem. or a game mechanic I'm not familiar with. I was playing as Portugal and had several wars with Castile. In previous wars I can declare war with a fabricated claim or colonial cassus beli and still demand unrelated provinces. But in the last two wars only the provinces I have a claims shows up on the list during peace talks. Any idea what might be the cause of this?

Okay, so even if the coastline appears discovered, I still need to send Explorer?
