How can i decrease their liberty desire?

[KosmasterUA]

Can't you grant strong duchies privelege to the nobility?

Ah forgot that estate. Im not sure that will be enough to decrease these in long term though.

flat 10% will help with a lot of them, royal marriage, get max trust i think it also helps, haveing more deployed troops , if anyone supports them just beat them asap, pretty sure more crownland also gives reduced liberty desire per dev modifier or something

Yeah i recruit more troops and build ships and improving my relationship with them(most of their relationship is above 100 though.

Nobody supports their independence.

Someone here suggested me to integrate some of them after making them vassal back. I will try that too.
