1460-1470: Punishing Agression
Fresh from establishing rightful Hapsburg control over Hungary, the HRE flexes its new muscles and forces Munster and Hesse to return unlawful territory, and they do:
It is nice to have your orders followed

. And to prove I am serious about this empire business, I take action when Trier insolently refuses to return Nassau:
(DOW on Trier and friends, inset shows Diplomatic ideas taken with innovativeness bonus)
On Trier's side were several german minros. On ours was Poland and Lithuania. So no contest. The war does trigger a small coalition led by Florence, but I ignore the puny Italians knowing I had a big alliance block to protect me.
Strategy for the war was to peace out the enemy one by one , and finish with Trier. I start with Munster, who is quickly occupied and forced to release Cleves as an independent prince, and cede Groningen to us:
(peace with Munster , insets show coalition started by Florence, England and Ottomans consolidating their backyards)
I chose to annex Groningen ( instead of releasing Frisia) to give me a power base in the North, so that I can intervene against future Center of Reformations in the area. I then proceed to peace out Palatinate , Frankfurt and Baden for money and prestige. Finally , it is Trier's turn:
(peace with Trier, discovery of silver in Tirol, changes in Iberia leading to Castile rivaling Austria, England consolidating Ireland)
In the peace , I return Berg to Cleves and release Nassau. Cleves really loves us now, having first released them in peace, and now returned a core to them.
During the war, I had the happy event of the Schwaz silver mines , giving a big boost to my gold income. But I also get the bad news of a Castilian rivalry . What happened is Portugal beat up Morocco, who dropped as a valid rival for Castile and they picked us instead

. So much for the old Austrian-Spanish alliance against France.
The release of Cleves and Nassau helps shore up imperial authority a bit . BUt this soon negated by Hesse annexing Mainz. But since Mainz was an elector, I quickly promote a grateful Cleves to their place:
(electoral college of the HRE. Succession is safe for now)
FOllowing these imperial interventions, I rest for a few years and accumulate money to Embrace the Renaissance and tech up to MIL 5. BUt my peace is rudely interrupted by a DOW from Florence, citing coalition WAR!:
(FLorence declares punitive war on Austria).
This took me by surprise, as I had several strong allies ( Poland, Milan and Brandenburg) and the coalition did not have a single Great Power. But I guess the annexation of Groningen did not go well with the other HRE princes. In hindsight, I should have checked the coalition icon when I made peace with Munster.
The next screenshot shows the two sides and the balance of forces ( about even):
I had the overall stronger side . But I was at risk of losing my smaller allies - Milan and Brandenburg - in separate peace treaties , while the enemy did not have worry about this . My first step was to neutralize Bosnia by annhilating their army in battle and then fully occupying them:
(general Schruder stackwipes the Bosnian , inset shows their capital falling 9 months later)
I then wheel my army north to defend Brandenburg who was getting overrun by enemy stacks. Plzen turns out to be my God-general's favorite battlefield:
(example of two stackwipes at Plzen - there were others)
THese skirmishes are then followed by a big battle at Straubing, a battle that starts medium and then attracts every stack in the vicinity :
My God general comes out victorious , as always ( I don't think he has lost a single battle yet!) .
The victory at Straubing gets me to within -28 of a white peace. But things go south again, as I divert my general to sieging Bavarian forts, and the enemy manages to mount a counter-offensive and defeats my allies . It is at this point that Burgundy decides to attack Liege:
(enemy counter-offensive underway when I get a CTA from Liege)
Man that CTA hurts. I kept the alert on screen for 2 months, watching how the war with Florence was going before I painfully declined, and lost -10 Imperial Authority . I really, really , wanted to answer and help Liege to gain IA. But there was no hope of reaching Liege at this moment, and I feared that a single Burgundian stack could tip the war in Florence's favor.
Fearing another external event like this ( an Ottoman attack on Hungary, for example), I hurry up the war with Florence and decide to take the war to their homeland. Once I captured Landshut in Bavaria, I use general Schruder to wipe out some stacks in Plzen area again, then head south to relieve Milan:
ONce the siege of Milan is lifted, it is onwards to Florence which is sieged by the God-general himself ( he has +3 siege pip) . Florence falls after 229 days:
(fall of Firenze , inset shows Burgundy annexing Liege)
But despite the loss of their capital, the Florentines would not agree to peace. It takes the capture of Ferrara, the carpet occupation of Papal States and Tuscany, the siege of Rome and another victory at Plzen to convince them of the error of their ways:
Finally, Florence takes a white peace.
I did debate at this point whether to continue the war and gain territory. In particular , I was eyeing either Ferrara ( estuary for trade in Venice node), or Papal state provinces ( to prevent Shadow Kingdom event). But I did not want to risk the coalition returning soon ( I had dipped under 50AE with everyone by now). And worried that an unlucky event ( eg. death of my beloved general, or Poland quitting the war ) would make my life miserable. So I played it safe and took the peace. Was it a mistake? Feel free to give your opinion.
This was the toll of this pointless war:
In the meantime, France had gobbled up Provence. Only Burgundy and a couple of English provinces stood between the blue blob and its natural borders. Apparently this leads Burgundy to seek an alliance with us:
(Burgundy asks for alliance from Austria)
I stared at this screen for some time. I had lost the ability to ally Castile as they have rivaled me. So Burgundy would be a natural ally to contain France. BUT, and this is a big but, Burgundy was the largest drain on imperial authority at this moment. If this was a standard run, I would have declined, and hoped for a French - Burgundian war and the inheritance. But this is not a usual run, and I decide to go for the alliance to counter France. This is my diplomatic map, with the 7 Great Powers labeled:
By allying Burgundy, the chance of the Burgundian inheritance firing drops tremendously . Burgundy is unlikely to get declared on as long as I am their ally. ANd if France does indeed declare, my reading of the "Succession Crisis" event says that France and HRE cannot be at war . So this alliance may very well mean Burgundy is here to stay.
By the way, another country that may very well persist into the future are the Mamluks. I am planning on pouncing on Ottomans the moment they declare on Egypt. I wonder what Mamluks would do if they are allowed to survive.
And as you can see in the screenshot, there are really 7 great powers in Europe. Three Eastern powers ( Poland, Ottomans, Muscovy) , three Western powers ( Castile, France, England) and one Central power keeping the balance ( Austria) .
Maybe I should adjust my criterion to NOT use the institution tech modifier ( makes the run easier), but use 7 great powers instead of 6 ( makes the run harder).
By this adjusted criterion , the current ratio between first place and 7th place is : 496/333= 1.489 which is barely, just barely, balanced.
