I want to know the answer to the following question:
What 2 powers named in the 5 orignal great powers of the congress of vienna have maintained that status?
All the background I'm provided with is that "The balance of power between the Great Powers became a major influence in European politics, prompting Otto von Bismarck to say "All politics reduces itself to this formula: try to be one of three, as long as the world is governed by the unstable equilibrium of five great powers."". Is that enough to answer the question?
Answer: no
