How Exactly Do Levies Work?

You can raise levies from any of your vassals, including your vassal's vassals. The number of levies you get depends on several things such as kingdom laws, holding prosperity (buildings) and vassal's opinion of you. Im sure there are other factors I just cant think of them right now.

Of course as long as they arent revolting. A Duke that revolts in your kingdom takes his vassals (counts/barons etc.) with him.

Ok back to work...

Edit: Your vassal's vassals are subject to their direct liege's laws, so if your a king and your Duke has feudal levies set to low, you only get what that law setting provides.

It took me a while to find, but a good tooltip to look at is if you hover over the right bar under the picture for a particular barony. It will tell you how big the levy is for that barony, and how many of the troops you will get based on various factors. A vassal's relation toward you is a huge factor in how many of the troops he will let you use.

To specify, I think you need to be in the military tab and hover over your vassals to see how many troops they are giving you and why.

Bad relations make it trickle down to nothinghood. "Gee golly my liege, I sure am sad to have so few soldiers in my employ: I could only spare 18 of them. Have fun fighting the Emperor!"

A baron under one of your vassals isn't effected by your laws, but his liege' laws.

As for levies, then it is the amount of troops you can raise.
This is a text taken from the CK2 manual:
"church levies – This toggle determines the amount of troops that church
vassals are formally obligated to provide."

This is very critical, many people are douches with everyone taking titles here and there, and then when a real crisis sets in you´re on your own. Having a nasty time as Duke of Lombardy because of that, thanks God that I´m married with the fatty duchess of Tuscany

Also, don´t forget to build castles as holdings and upgrading them. They give a lovely bonus for raising troops.
