Marc Morris is an historian and broadcaster. He studied and taught history at the universities of London and Oxford, and his doctorate on the thirteenth-century earls of Norfolk was published in 2005. In 2003 he presented the highly-acclaimed television series Castle, and wrote its accompanying book. Following the success of his biography of King Edward I (A Great and Terrible King, 2008), he is now writing a new history of the Norman Conquest.

Beginning with their introduction in the eleventh century, and ending with their widespread abandonment in the seventeenth, Marc Morris explores many of the country's most famous castles, as well as some spectacular lesser-known examples. At times this is an epic tale, driven by characters like William the Conqueror, King John and Edward I, full of sieges and conquest on an awesome scale. But it is also by turns an intimate story of less eminent individuals, whose adventures, struggles and ambitions were reflected in the fortified residences they constructed. Be it ever so grand or ever so humble, a castle was first and foremost a home. To understand castles - who built them, who lived in them, and why - is to understand the forces that shaped medieval Britain.
