Did you maybe mean burg?
“AD 907 – Chester refortified by Aethelflaed Lady of the Mercians to create a defensive burh.”
“The difference being that if you were a burh defender you only had to serve in your local area a sort of Home Guard, if you like, while if you were in the king's army you were expected to fight away from your local area if need be.”
“Mason's tantalising mention of "subsequent refortification" predating the medieval wall is also undated, so although it seems plausible to attach it to the burh of 907, it could be considerably earlier.”
“The king's army service might be closer to modern reservists, though I would expect there was a lot of overlap, and no doubt people who had served in the king's army would also serve in their burh defence, either instead perhaps when they got a bit older? or as well as army service.”
“The size of each burh was determined by the population it served, with 1 hide (a hide was the amount of land required to support one family, roughly speaking, although as you would expect (!) there are disagreements about its definition) = 1 man = 4 yards of wall.”
“The burh system required one man per hide to defend the burh when needed, and one man per five hides had to serve with the king's army for part of the year.”
“When danger threatened, the people living outside were supposed to move into the burh for their own protection and to contribute to its defence.”
“The population served included the people living in the burh and those living in its immediate area within about 20 miles or so.”
“Whether burh defence would come under 'troops available for muster' I'm not quite sure.”
“Should the writer use 'frith' instead of 'peace', or 'burh' instead of 'fort', or 'cyrtel' instead of 'dress', or 'hegge' instead of 'fence'?”
These user-created lists contain the word ‘burh’.
Shamelessly ripped off from this site and others (to be named hereinafter). (Fair warning: for my own edification, I may add definitions/comments from the site, but you might want to just go there ...
Words for things both tangible and anthropic. I'm in the process of spinning off hardware into ute, and people into oofy.
Verbal curios, because of their meaning, their shape, or their history.
Looking for tweets for burh.
