This book is written by Russia's late expert in the country's history, which is one of the reasons why this book is important to every medieval history student. It's quite easy to read- cause the author divides the book into many small chapters, which cover only one subject at a time. This is a huge asset, since many history book tend to rush from one subject to another- leaving the reader confused and irritated. So for those who don't like the thought of a dry treatise- don't worry it's very accesible!!!! The author's knowledge is evident, it's written with security and straight-forwardness without unneccesary complications. There's no specific point of view, from which the book is written, so it gives a good, thorough review of this remarkable era in Russian history. Good for non-experts in medieval history- but also nice for historylovers!!
