The extent of the medieval district of Craven, in the north of England is a matter of debate. The name Craven is either pre-Celtic Britain, Britonnic or Romano-British in origin. However, its usage continued following the ascendancy of the Anglo-Saxons and the Normans – as was demonstrated by its many appearances in the Domesday Book of 1086. Places described as being In Craven in the Domesday Book fell later within the modern county of North Yorkshire, as well as neighbouring areas of West Yorkshire, Lancashire and Cumbria. Usage of Craven in the Domesday Book is, therefore, circumstantial evidence of an extinct, British or Anglo-Saxon kingdom or subnational entity.

Shire is a traditional term for an administrative division of land in Great Britain and some other English-speaking countries such as Australia and the United States. It is generally synonymous with county. It was first used in Wessex from the beginning of Anglo-Saxon settlement, and spread to most of the rest of England in the tenth century. In some rural parts of Australia, a shire is a local government area; however, in Australia, it is not synonymous with a "county", which is a lands administrative division.
