Derbyshire
In general, the Midland counties lack geographical definition, but Derbyshire provides a partial exception. The High Peak serves to divide it from its northern neighbour, Cheshire; and, in the medieval period, the forest of Charnwood in Leicestershire was a barrier of sorts to the south. Further, some three-quarters of its borders are delineated by rivers, principally the Erewash and Dove, which define boundaries with Nottinghamshire and Staffordshire respectively. Politically, however, the fifteenth-century county had a more divided aspect.
