Marry one of your close relatives to one of theirs, and the alliance will be formed. In the middle ages, alliances were formed by marriage. Otherwise, your kidnap chance will be very low.ДonвЂ™t worry, though there is another way to force their loyalty. To kidnap people, your character needs to be skilled in intrigue. Then torture and execute a few and enjoy your stable realm. If they will revolt, use your jailed vassals levies to crush them. They will be forced to stay loyal to you. Kidnap your strongest vassals and have them under house arrest. This perk allows you to kidnap people (duh). After this, torture to your heartвЂ™s desire! ItвЂ™s called вЂњDivine Retribution,вЂќ and it prevents the piety loss from executing and torturing. Simple, get the second perk of the left side of torturer tree from intrigue lifestyle. Piety is hard to come by, and you need it for your holy wars. Doing bad stuff to prisoners of your own religion will lose you 100 piety. Torturing peasants are like medieval common sense anyway. Imprisoning or torturing unimportant people like lowborn wonвЂ™t do anything because no self-respecting noble gives an в™Ґв™Ґв™Ґв™Ґ about peasants. Imprisoning and torturing important people also gives you dread. Those play a lot closer to CK2, keep your vassals happy and all that simp. DonвЂ™t use the hard rule tactics with clan governments. So while you can keep them in line by dread, you will be very weak. Crown authority forces them a minimum amount of levies and vassals, but itвЂ™s too little.

Since youвЂ™re keeping them in a constant state of fear and tyranny, they wonвЂ™t give you anything, even if they canвЂ™t rebel against you directly. I attack a powerful country like HRE and farm fame by battles.Д¬lan vassals give levy and tax based on their opinion of you. If youвЂ™re playing tribal, make sure to do many battles, they give massive fame. As with feudal, you can do whatever you want as long as your fame is high.

Tribals give levy and tax based on your level of fame.

Ck2 great holy war
