I read a history of Poland and Hungary and wae considering a good book about Russia but wound up reading a history of the Romanovs which I enjoyed. Anyway, this is the first of a 5 part series. It's often said that Russia is not quite Europe and not quite Asia but I wonder if this question of identity would exist but for the Mongol invasions. For over a century Russia was pulled out of its European orbit. This as also during a formative period of European history. Enjoy.
