Why is the arthe size halved

When my king died, the next king (oldest son) could only raise like half the army (levies) I could before. What happened?

I think the reason your levy decreased is due to your heir's vassal-leige relationship score being different than your original king's. It could also be that your levy base providing buildings are not in your heir's personal demense.

The levy system is actually kinda complex but once you have a feel for it I suspect it'll make sense.

I originally said (in comments) that I thought this was related to titles, and it's not quite right. There's a few things at play.

If you don't give your sons any land then you can end up with the "unlanded sons prestige penalty". You need to give your first son some lands (but not the 2nd or 3rd as it'll increase a chance of war on inheritance). This shouldn't affect your levy though, except as it may indirectly affect your relationship with your vassals.

I came across a pretty decent description of the levy system [here].1

If you lose any of the following, you'll see a bad drop:

  • Castles give 225 base Levy (150 HI, 60 LI, 15 LC)
  • Churches give 130 base Levy (45 HI, 45LI, 40A)
  • Cities give 115 base Levy (75LI, 40A)

Here's where you could be losing levy... especially note that if the castle isn't in your personal demesne you'll take a hit.

You raise 100% of the Levy in your own holdings. Since castles give the most and best types of troops you want to have castles in your demesne unless you don't want to use only mercenaries and vassal levy.

The following is what I was talking about with the V-L Relation

Relation with your vassal and Levy Laws determine how much of the vassal levy you can raise. Crown Authority sets the minimum levy you get and Levy Laws set the maximum:

Crown Authority → 0 min /10% min /20% min /30% min /40% min Feudal Levy Law → 60% max / 70% max / 80% max / 100% max (225) City Levy Law → 50% max / 65% max / 80% max / 95% max (115) Church Levy Law → 50% max / 60%max / 70% max / 80% max (130)

You always get the min levy set by crown authority but the actual amount up to the >maximum is determined by vassal-liege relation (VLR). Relation is transformed into >percentage value (P) according to the following formula:

P = ((25 + VLR) x 0.69)/100

Now when you apply P to the maximum levy set by law (MXL) you get the percentage of >troops (PT) you get from the holding:

PT = P x (MXL/100)

Multiply by the number of levy (NL) in the holding and you get the actual troops (AT) >you can raise:

AT = PT x NL

Hope this helps and good luck! Sorry about any confusion!
