How to join a kingdom in WFaS

[unmerged(271561)]

Ok, in my game. I intend to join the Cossacks. They are at war with the Khans, who occupied the capital. I personaly beseiged it and won. So now I'm my own nation. I was wondering if I get high enough renown, can I become a vassal?

Note: Even after all that, i only have 27 renown lol

You need around 150 renown to become a vassal.
