Relations between England Russia over the past 500 years represent a unique phenomenon in world history. During this period, allied or at least friendly relations between the two great powers accounted for no more than 50 years. The rest of the time is fighting or the Cold War. The phenomenon of the great confrontation is that all other states of Europe - France, Germany, Sweden, etc. - waged wars among themselves over border conflicts or over the ownership of disputed territories. England Russia have never had a common border and territorial disputes. What is the essence of this great confrontation and why was it interrupted by temporary military alliances? This and many other things are described in the book of Alexander Shirokorad "Russia and England: 50 years - allies, 450 years - enemies."
