A change is as good as a holiday when it comes to diplomacy, but Bruce and Barry will be back in the dungeons soon enough. 
Relations with the Portuguese are about +50. The Austrian navy has 3 warships, 7 galleys and 2 transports. Not really enough to take on the Portuguese, I think, but it might be worth a try.

Chapter 5, Part IV
In which Austria inherits Protestants
September 1526
Scene: The library that Bruce and Barry have been gradually converting into their office. They are poring over a number of documents.
Bruce: Its a stroke of good luck King Louis of Bohemia and Hungary carking it like that. Karl and Ferdinand are still sorting out between themselves who is gonna run what, but however you look at it, its a win.
Barry: I heard Ferdinand is going to become King of Bohemia and Hungary, but they are both going to end up part of Austria?
Bruce: Thats the gist of it, yeah. We'll be running the whole show from Vienna, and Ferdinand will be answerable to Karl.
Barry: Hmmm ... there will be economies of scale if we just have a single central government. *nods* That makes sense to me, but why would Ferdinand want to do it this way?
Bruce: Karl and Ferdinand are very big on the family unity thing. But I think the real reason is that Ferdinand doesn't want to go and live in Hungary.
Barry: *suddenly worried* We're not going to have to go instead are we?
Bruce: *shrugs* We'll have to visit sometimes, probably. But we'll stay based here in Vienna.
Barry: Phew!
Bruce: The only catch is that the rest of Europe seem a bit wary of us now.
Barry: I can understand that. Is it a problem?
Bruce: I can't see the Spanish giving us their maps now.
Barry: It didn't seem like they were too keen to do it anyway, so its not a big deal.
Bruce: We need some sort of maps to get to Australia, Barry.
Barry: Well, since everybody hates us now, maybe we can fight a war against someone and steal their maps?
Bruce: Have you seen the navy lately, Barry? They'd struggle to fight their way out of a wet paper bag, let alone steal maps off one of the major naval power of the century.
Barry: Oh ... Well it was just a thought.
The map Bruce and Barry have been studying. Austria suddenly looks much Bigger, Whiter and Blobbier.
At this moment, the emperor himself enters the room unannounced. He spots the new map on the table.
Karl: Ahhh, good! I see you two been looking over the details of our new territories. This is going to more or less double the size of the empire here, so Ferdinand and I will be needing your help.
Bruce: We've been going through the records we have available to us.
Karl: Anything important you have spotted?
Bruce: The combined armies of Bohemia, Hungary and Austria are too big for us to support, my lord. Do I have your permission to disband some of the troops?
Karl: Very well, but do not disband any armies in Austria. If the idle troops are to make any trouble, I would prefer that it happens in the wilds of Hungary.
Bruce: Actually, I was thinking of disbanding the troops in Bohemia.
Karl: I understand the people there are Protestants?
Bruce: In the provinces of Bohemia, Silesia and Sudeten, my lord, yes.
Karl: We must do our best to convert them back ... but in the meantime, I would rather they suffer than the good Catholics in the rest of the country. Disband the armies there.
Bruce: No problem.
Karl: Anything else?
Barry: The new provinces are used to a more decentralised form of government. By absorbing Hungary and Bohemia, our overall government centralisation has decreased considerably.
Karl: That is unfortunate. How are the Hungarian provinces governed then?
Barry: The local aristocracy are very much used to getting their own way. They have powers that the Austrian nobility have not had in centuries.
Karl: We will fix that, no doubt. But for now, we must leave things as they are. No point in provoking a civil war. Not yet, anyway.
Barry: Will you be travelling to your new lands now?
Karl: Hmmm ... Winter is coming on, but perhaps I could squeeze in a visit ...
Bruce: Visiting Hungary has not always been safe for the Habsburgs, my lord ...
Karl: You are referring to my predecessor, the Archduke Albert, perhaps? *Bruces nods, slightly* Times have changed since then. The Hungarians have become much more civilised ... But, I am sure that there are matters requiring my attention in Spain. I should reassure my subjects there that my attention will not be diverted by these new lands of mine. All in all, perhaps it would be better to send Ferdinand and Anne. The Hungarians will surely recognise
her as one of their own, even if they do not feel the same way about me or my brother.
Bruce: A wise choice, my lord.
Karl: You two should go with them, of course. Get the lit of the land and all that.
Barry: But ...
Karl: You can send your reports to me in Madrid. Enjoy your trip gentlemen.

October, 1528
Scene: The imperial thronerooom. Bruce and Barry are waiting for permission to enter. Meanwhile, the narrator is moving around the walls, tapping on them and then pressing his ear to the wall.
Narrator: Of course, wooden building, such as this one, that were common in the 16th century, were prone to a number of attacks. Termites were a particular concern, and prior to the invention of chemical pesticides, a number of folk remedies were used. Successfully in this case.
Attacks on the body politic were similarly feared, especially here in Austria. The Austrian Wars of Religion did not end with the subjugation of Saxony at the end of 1524, but a new phase began. The Habsburg inheritance of Bohemia, along with the addition of Anhalt to the realm, meant that there were now large numbers of Protestants within Austria's borders. Austrian troops, good Catholic troops, were sent to the most strongly Lutheran regions, and with them came missionaries, hired at great expense by the Austrian throne.
Despite these precautions, the Bohemian and Hungarian lands remained peaceful. Ferdinand's tour, accompanied by Bruce and Barry, proceeded uneventfully. In the autumn of 1528, Karl returned to Vienna, where he met with Bruce and Barry.
Barry: Its good to have you back in Austria, my lord.
Karl: I thought it best that I return for von Frundsberg's funeral. He was such a loyal servant of my father's, and of mine, in the last few years of course.
Bruce: I am sure his family appreciated it, my lord.
Barry: Before we go on, can I just mention, that I am not happy about the amount of money that is being spent sending missionaries all over the place?
Karl: Your objection is noted. And I have read your letters to the same effect. So many letters ... However, it is important that we stamp out Lutheranism as quickly as we can.
Barry: You'll never manage it.
Karl: Don't be so defeatist. If the missionaries don't work out we can always switch to simply rounding them all up and killing them.
Bruce: I really can't recommend that, my lord. If the Lutherans are going to be killed anyway, they will fight your troops tooth and nail. The whole of northern Germany will become blood bath.
Karl: *sighes* Yes, yes. I still think it would be the simplest solution, but I do see your point. If only Luther's teachings had not spread so widely ... We will keep funding the missionaries.
Bruce is relieved at that, but Barry continues to look unhappy.
Karl: Now, apart from the religious crisis, I asked you two here today to congratulate you on successfully arranging my cousin Albert's wedding.
Barry: Who?
Bruce: Albert. We found him a wife in the Teutonic Order.
Barry: Ohhh ... Well done us then, huh?
Karl: Quite. Since that went so well, I have decided to set you another diplomatic mission. I want you to vassalise Savoy.
Bruce: Err ... My lord, Savoy are no longer a part of our alliance.
Karl: Really? Oh, well, you'll just have to bring them back, won't you?
Bruce: They have formed a new alliance with Munster and Scotland. They have also annexed the Swiss.
Karl: Ahhh ... That is a little more challenging than I had intended it to be then. *Karl looks not at all worried by this discovery* But at least the Swiss are out of our hair for now. Oh well, best of luck!
