I want to know the answer to the following question:
What was took place in 1854-1856?
All the background I'm provided with is that "For a while it appeared that another war would be inevitable, but the two countries reached an agreement on their respective spheres of influence in the region in 1878 and on all outstanding matters in 1907 with the signing of the Anglo-Russian Entente.". Is that enough to answer the question?
Answer: no
