Hwicce. Article #15. Vol 6, pg 183.
The Hwicce were the inhabitants of one of the sub-kingdoms in Anglo-Saxon England, from around 580 AD to 780 AD. I guess being just a sub-kingdom explains why Britannica only gives them about an inch. They were actually their own kingdom until 628 AD, when they got subsumed into Mercia and relegated to a sub-kingdom.
Mercia gets several inches in Britannica, by the way.
