The Corieltauvi tribe had moved to Britain from continental Europe some time after 100 BC. They were a confederation of Belgic warriors who carved out a kingdom which stretched from the Humber to south of Leicestershire. These ancient Britons were not really a unified tribe, but a collection of like-minded peoples sharing the same outlook and way of life. The tribe generally did not rely on hill forts for their protection. It appears that the Corieltauvi were better farmers than warriors, for they lived in lowland settlements, usually beside streams, frequently surrounded, or even hidden, by areas of thick forest.
