The Middle Ages may be considered as a somewhat indefinite period, and their chronology cannot be very exactly defined, but for the purposes of this book the portion of the mediæval period dealt with is that which commences with the Norman Conquest and ends with the Battle of Bosworth.
It is impossible to exaggerate the enormous influence of the Norman Conquest. The Saxon period was as thoroughly mediæval as the Norman period, but our full knowledge of history begins with the Conquest because so few historical documents exist before that event. Moreover, the mode of life in Saxon and Norman London was so different that it would only lead to confusion to unite the two in one picture.
In order, however, to show the position of the whole mediæval period in the full history an introductory chapter is given which contains a short notice of some of the events during the Saxon rule, and a chapter at the end is intended to show what remains of the mediæval times were left when Shakespeare lived and Johnson expressed his opinion of the pre-eminent position of London.
It is necessary for the reader to bear in mind that London means the city and its liberties up to the end of the eighteenth century. The enlarged idea of a London in the north and the south, the east and the west, is a creation of the nineteenth century.
