The post-monastic liberties have long formed a footnote to the history of early modern London, but they have escaped serious historical consideration on their own merits.

The second chapter focuses on the City of London's relationship with the liberties in the century after the dissolution. A chronological survey of its approach to the liberties precedes a thematic discussion of the issues that affected that approach. The following chapters present in-depth study of four post-monastic liberties. They explore the development of administrative and social conditions within each liberty and consider the relationship of each to outside authorities. Because of variations in the survival of sources, different aspects of each liberty's history come to the fore.
