Question

and also what were prince metternich's three guiding principals at the congress of vienna?

Answer 1

Ref Napoleon

1. The creation of Holland and Westphalia
2. Strengthening of the British military machine
3. The creation of alliances across Europe

(Most of the above also have negative sides in their ultimate contribution to WW1)

As regards Metternich see the attached link

Answer 2

1. spread of nationalist ideas to the rest of europe
2. spread of constitutional government (Napoleonic Code) to Europe while occupied by the French
3. Discovery of Ancient egyptian secrets...the rosetta stone
4. creation of Confederation of the Rhine which united the German states under a common ruler and later led the way to a united Germany under Prussia
5. One might argue that Napoleon's conquering and uniting of all of Europe and the attempt at Russia may have been an influence to Hitler
6. The destruction of the HOly Roman Empire

Guiding principles of Congress of Vienna
1. Restore the old regime and the idea of legitimacy in monarchial rule throughout Europe
2. keep a balance of power throughout Europe which would make sure no single power could dominate Europe as France did
3. Keep the peace through a European peacekeeping organization, the Concert of Europe
4. Make sure France never again becomes a powerful military force by taking her territories and land and giving them to surrounding countries (northern italy given to Austria, Brussels added to the Netherlands, Rhineland given to the German States, French colonial lands divided among Britain, Austria, etc.)

hope this helps
have a nice day.
