In exchange for that, the vassal gives the lord resources, taxes, and loyalty. Now, the way I drew it here, it seems quite organized and clean, but the reality of it, it isn't that clean. Sometimes, a kingdom might directly, some parts of it might be subdivided into duchies, some of it might be divided into a county that is independent of any duchy. You might have another duchy right over here that is not subdivided into counties. You might have one count that is more powerful than another count, or one count that might even be more powerful than a duke someplace else, so it can actually be quite chaotic and hard to keep track of, and this isn't all of the players. I mentioned some of the titles of nobility like duke and count, and then below count, you might have a baron. In England, the equivalent of count was an earl who still presided over a county, and their wife was a countess.
