I had to do it, at that point my wife Matilda got jailed as usual for years and was unable to provide more than one living (DAUGHTER) child and eventually died in jail. I divorced her and got betrothed to this girl who also failed to produce more than 1 male child and couple of girls before Miles was imprisoned for having claims and died in jail. Now I'm rocking the scene with the only male of my dynasty. Miles' eldest daughter inherited Matilda's things and married matrilineally to a Premyslid prince but was jailed prematurely and has produced a mere 2 daughters before her inevitable death. For some reason my family has a tendency to be jailed which is irritating as hell.42 and betrothed to a child? Tisk tisk tisk. You perv. (sarcasm, its just a game)
On a sidenote Boleslaw united Poland & HRE under his leadership, and Jimena Castille has fallen to a portuguese ducal dynasty. HRE is seriously blobbing in this playthrough, and ridiculously a monstersized Bulgaria now rules all of old byz after the title died.

This is a record breaking number of kings in that space of time, imo.

Vimaranes! The rising dynasty of Iberia.
