Royal Bastards of Medieval England [PDF ebook] 

First published in 1984, The Royal Bastards of Medieval England establishes a list of royal bastards in medieval England, and discusses their roles in the history of the period. The authors describe how gradually the church began to formulate more definite views on sexual and marital customs, with a consequent decline in the status of illegitimate children. By early sixteenth century, however, royal bastards were once again making their way into the peerage. The book charts the lives of these men and women against the background not only of contemporary political developments, but also of changing ideas about morality and family. This book will be of interest to students of history, religion and literature.
