Why was England at war with Russia?

Answer 1

England would need to separate from the rest of Britain in order to make an independant decision about going to war, or not going to war with Russia, so the simple response to your question is that England was at war with Russia because Britain was at war with Russia. If your question is about Britain being at war with Russia, then you must be referring to the Crimean war. The reasons behind that war are many and varied including religeon, the breakdown of the Ottoman empire, "knock on" effects of Napoleon III's ambitions and the desire to prevent Russia gaining power in Europe. If your question is not about the Crimean war, then inthe strictest sense, it has never been at war with Russia, only political and covert operations.
