My last king of Poland was quite fun, his reign started during war for duchy of ostmark started by his father so he could create kingdom of pomerania.
War was actually almost finished but then king of bohemia declared war on me for some county. I said ok and i finished last war and went to battle.
But then claimant started civil war, my pagan subjects revolted and my only ally, king of hungary gets invaded by hre because some czech duke had claim on hungarian crown. It cost me a lot of time and save scumming ( once hungary was even invaded by byzantium), many times czech war was invalidated, hungary incorporated into hre, liberty faction revolted and second claimant faction revolted.
Finally i did it, i imprisoned first claimant and released him without claims, agreed to lower crown authority, won war against czechs with help from 2 freshly allied hungarian dukes, destroyed revolters and hre didnt invade hungary.
By that moment it was like 5 years of constant wars. After that i denounced second claimant and every time his faction declared war it somehow got invalidated. Finally claimant war happened and somehow i did it and won even though revolters army was twice as big as my. And then crusade started, i joined with half of my army and went to holy land.
During my crusade my ally king of Hungary died and his heir lost war against hre and got incorporated. Pagans revolted again and i got small peasant uprising.
In Holy land my king destroyed two armies of saracens and quickly conquered 4 counties (one full onager and perk engineered destruction will make siege last 24 days instead of 5 months) . Crusade ended and my aunt became queen of Jerusalem. My home army destroyed one revolter army and i allied with king of denmark so he would help me to clean this mess. When my second army with my ruler finally reached home, king of denmark started war with norwegians. I sent my first army to Norway and my king eradicated pagan rebels. King of denmark won and my 1st army returned just to join my vassal conquest of prussia ( fucker turned my borders into border gore).
We won and some peasants rebelled, they had small armies but one army was in Szczecin and other was in Cieszyn. And then king of ruthenia invaded.
I defeated him and created first holy order in whole game, then it was peace...
No
I needed to conquer duchy of nordmark, it was controlled by hre, hre was allied with kingdom of Sweden and kingdom of ruthenia. I had only one ally, croatia.
So i started that war.
I expected king of ruthenia to attack my eastern borders and my armies to be overhelmed by hre armies. Nothing happened, i sieged two counties and finally i saw enemy army. That army only had 2k soldiers compared to my 5k army so it got destroyed. I sieged rugen, one other county and then i finally saw ruthenian army.
That moron instead of attacking my unguarded borders tried to transport his armies to rugen through baltic sea. Of course i went there and welcomed him with my army. His ass was beated hard and i returned to conquering, i beated then many other hre armies and one swedish with good maneuvering and small help from croatian forces that finally arrived. For almost whole war i was only looking on that one duchy that i was conquering, and then when i had almost won i looked from bigger perspective...
It was like cancer, 1/5 of my kingdom and whole kingdom of bohemia was under kingdom of jerusalem (whose ruler was a muslim), hre was ravaged by border gore and many dukes and counties were suddenly independent. I was like wtf is happening? Probably some inheritance shenanigans + my aunt lost holy land to goat fuckers. I finished that war and started another one so i could clean that shit. After many months i did it and i had peace for few years, then in a series of 3 wars i usurped kingdom of bohemia.
Finally after 40 years of rule, King Mieszko II (actually III ) united west slavs, year later he died and his weak heir now fights with gigantic rebellion.
