Is this a homework question? Its phrased like a homework question.

This is a question very close to what I do in my field. I'll try to keep it short-ish.

The main question facing the concert was how much of Napoleonic change to role back on mainland Europe. To some extent, the cat was already out of the bag. They couldn't, for instance, reconstitute the Holy Roman Empire, or take France out of the picture as a major power. However, the system could work if the majority of the states were involved in resolving disputes in an organized way - but at instances in which one or more of the countries was unwilling, this was more difficult. This is why we see great consensus at the beginning - see the last coalition fighting and defeating Napoleon at Waterloo. However, while the political ordering at the top of countries could be maintained, forces in the populace generally favored liberalizing, and generally destabilizing forces.

This meant that the concert was faced with the paradox of restoration - in order to keep restoration going, they had to give in to some demands - but this of course meant they weren't really restoring things. While some political shifts kept up (think the Orleanist takeover in 1830) there was no way that by 1848 the political ordering could stay the same with a population that had changed so significantly throughout Europe since 1789.
