Loyalty is, basically, how much the villagers of your village like you as the current ruler.

Every village has loyalty, between 1 and 100%. If this number falls to 0, the owner of that village is changed to whoever sends an attack against the village that includes a Noblemen. Normally, unless you have been attacked with a noblemen lately, you will have 100 loyalty. Your loyalty is displayed underneath your units in the village overview, but is hidden when at 100%. Another thing that is useful to know is that loyalty raises 1% per hour, multiplied in faster worlds. For more information on how to lower loyalty, see Nobling or Noblemen.
