SpecialNewb wrote:The original word means fortified settlement so it works for both. Certainly towns were fortified in some manner and some forts grew into towns. I see what you are getting at when you say it (ed: Burg by itself) points specifically to a settlement, but to say that merchants and artisans were outcasts from castles is going a bit far.
In regards to the Undead Burg, I think it was a protected (fortified) settlement outside Anor Londo. It was for people that worked in Anor Londo or in some other way did the bidding of the gods. There are only so many of them and lots of work needs to be done (building Anor Londo for one!).
I really did not want to get too much in depth in my little History Class. lol
I highly recommend you to read about the people that lived in the Burgs: http://en.wikipedia.org/wiki/Bourgeoisie
They were indeed outcasts. Remember, it is the Middle Ages; God is supreme and the occidental society is separated between nobles and the common rabble.
A normal Castle is more like a farm, than the legendary thing movies and stories tell about. There was the Castle, where the Lord and the nobles lived. Soldiers and Knights all belong to the noble class. Their servants also lived in the Castle (maidens, blacksmiths, craftsmen and etc).
And there was the peasants; they took care of the farms and the woods inside the Castle walls. They lived to serve their Lord and maintain the system.
HOWEVER, over time a 3rd group was born: the bourgeoisie. They unlike the peasant and the Castle servants, wanted independence from the crown. They became traders, and slowly became as rich as kings, sometimes even more powerful. The Church and the Crown, prohibited "commerce" within the Castle walls; because Greed is bad. So the bourgeoisie created Burgs, outside the walls to trade freely.
Finally the part you were worried about: Of course they wouldn't just stay outside, unprotected. So Burgs usually had walls and keeps of their own. Mercenary armies were not unheard of, since the bourgeoisie was rich enough to pay for them.
When the Lords noticed Burgs produced quite a lot of money; they started to take taxes and officially support it; by protecting it and etc. However a Burg kept being somewhat of a independent city inside a kingdom.
A Kingdom could have more than one Burg, depending on its size. They were usually located at crossroads, ports or even, just outside the Castle walls.

Substitute bourgeoisie for Undeath, and ta-dah! We have the Undead Burg story, and why there isn't Silver Knights protecting the city.
Church says Undeath is bad. Undeads are kicked out of Anor Londo; make a city of their own (a Burg) in the crossroad between Oolacile and Lordran - my guess is that New Londo came first. The city is flooded; they create a second city: Undead Burg.
Kings feared the bourgeoisie's power. Gwyn feared the Undead.
In the end, bourgeoisie would step down their Kings and create Republics. The French Revolution being the first example. Which started with the people freeing enemies of the Crown from a prison.
The Dark regardless of your choice will prevail; and the Revolution (even Logan calls your actions that) starts with your prison break. A prison that holds enemies of the Crown - the Undead.
