The Congress set up a balance of power between the five Great Powers of Europe:
- Prussia (Germany)
No one country
could overwhelm the allied armies of the other four.
The French monarchy was restored by making Louis XVI's brother the new king (he took the title Louis XVIII--Louis XVI's
son was killed in the revolution).
Eventually, the five nations became
involved in a gigantic
arms race, which led to the outbreak of World War I.
