Back to the Piast
- is Mazovia.
The player is not playing as a released vassal.
The player’s country:
- is Poland.
Teutonic Order starts off with a truce with Poland, so waiting out the truce will allow Poland to make very beefy allies. Start to improve relations with Hungary and Bohemia, then ask both to support your independence. Build 5 infantry regiments, when they are ready send your army to Krakow. Lithuania will very likely ally Poland within the first month of the game. Start your independence war before Poland gets the personal union with Lithuania. If not the war will be extremely difficult even with your allies. Peace out Lithuania and other allies. Now siege Poland until maximum warscore (should be easily done after Lithuania is out). It is possible to remain subject to Poland and only take provinces or release Galicia-Volhynia to weaken Poland in the next war.
Another hint: With your high war exhaustion and negative stability you can let the peasants or magnate rebels siege your capital and break your country, because they will reset stability and war exhaustion to 0. This saves you some monarch power and can possibly be used as a defense against Poland attackers.
The next wars can be fought with the support of the Bohemia and Hungary again, Teutonic Order (if they did not switch rivals from Poland, which happens often), or maybe with Lithuania (if they are no longer allies with Poland), or if you are still subject to Poland: Moldavia. If their liberty desire is over 50%, they should accept an alliance with you.(Only possible if you remain subject after the first war). Another advantage is that Poland often has no strong allies while they still have 3 subjects.
