It's hard to pick just one or two, but a couple of instances of Pomeranian abuse stick out in my mind.
1 - A while ago, playing as the petty king of Pruthenia, I set my sights on the much larger petty king of Pomerania, who had gobbled up a couple of his neighbors. I had about 3/4 of the men he did, so I devised a plan: I would murder him and split his realm in half, between his two sons. As icing on the cake, they were 13 and 5, respectively. The murderplan went off without a hitch and I declared a subjugation war on the older son, easily crushing his armies with a few mercenaries that I paid for with gold raided from the Christian kings to the south. I sieged down his lands and, just as I was about to capture his capitol, it struck me: He was the heir to his (now 8 year old) brother's lands, and his brother was the heir to his lands.
I occupied his lands, concubine'd his wife, and captured him in a final battle against the pathetic remnants of his army. I put him in house arrest and six months later, his younger brother dropped dead (erring on the side of caution, because inheritance can cause screwiness when a target dies in the middle of a war.) The older brother inherits his now dead younger brother's lands, and I crush his newly raised armies before ending the war despite having him in my prison, just to be thorough. I end the war, gaining all of the lands I originally had my eyes on without ever having to fight the full might of Pomerania (which is kind of an absurd sentence, given the strength of Pomerania) he goes free, and I assassinate him within a year. His family's lands pass to me, as I've extinguished his family's line, and I distribute them among my loyal landless generals.
2 - In a much more recent game, I was the Fylkir of all Scandinavia and Russia, and set my sights on eastern Europe. I invaded Pomerania and immediately captured a random princess, who I of course immediately make my concubine. A handful of Christian kings come to his defense - just enough to get me sailing back to Scandinavia to lick my wounds - when I look at the princess - Wroth, ambitious, Brawny, a martial of 17, and she LOVES me. I ask her to convert, which she does happily, and I release her from concubinage and make her a shieldmaiden. This princess of Pomerania lead my armies to half a dozen victories against the combined armies of Pomerania, Pannonia, and Poland, personally fighting against her father and laying waste to her own family's land at my command, leading what I can only assume to be a horrifyingly demoralizing campaign against the Christian countries.
