The Cromwellian Proectorate is often a difficult topic for many A Level students. However, this book clearly examines this period in a structured, logical and, importantly, accessible style. Coward is a leading historian of this era and he has the gift of explaining this period in a way that students understand.
This book, I feel, is Coward's best as he actually makes this period come alive with fascinating comments and interesting asides. For students studying this period for A Level, I would have no hesitation in recommending this book as an essential read for your course.
