The greatest virtue of this book is its succinctness. That's also one of its drawbacks, however. It covers 1200 or so years of Russian history in only 250 pages. If you're reading this book in the first place, you're probably already familiar with the broad outlines of Russian history, and this book won't do much to deepen that knowledge.
Perhaps the single greatest insight I gleaned from this book is the author's dismissal of the idea that the Mongol invasions of the turn of the second millennium have much to do with Russia's historical backwardness and violent history. The author contrasts Russia's path with that of the Spanish, whose country was occupied by the Moors for 700 years, until expelled in 1492. Russia, by contrast, was only under the Mongols for 250 years. Moreover, the Moors actively occupied Spain, whereas the Mongols stayed on Russia's periphery and merely collected tribute from their Russian vassals, leaving them to run their own affairs otherwise. Yet Spain today is a prosperous democracy whereas Russia is a ramshackle autocracy currently engaged in a bloody war of aggression against its Ukrainian neighbor. I think the Mongols can be left off the hook for Russia's modern-day failings.
If that's not the explanation, what is the reason Russia has never made the transition to even a semblance of being a prosperous democracy? There are a lot of possible explanations, but these are not really explored in this book other than in the form of some almost offhand comments.
Personally, my choices for some of the reasons for Russia's failure to become a modern Western state would include: making the mistake of creating a multi-ethnic empire; growing so large in geographical area as to be almost ungovernable; creating a conservative, insular state religion (the Russian Orthodox Church) that complicated the business of running a multi-ethnic empire; failing to get rid of serfdom until very late in its history, centuries after it had disappeared in Western Europe; and being unlucky enough to fall under the sway of a handful of Marxist revolutionaries who, against all odds, managed to overthrow the state in 1917 and hold onto it through the Civil War that followed. The Bolshevik revolutionaries then proceeded to govern much worse than the regime they replaced.
