Before the Atomic bombs were dropped the Americans were dropping explosive and incendiary fire bombs. They dropped them in such massive numbers that entire cities were destroyed resulting in the deaths of hundreds of thousands of innocent civilians. To the Japanese military it didn't make a difference to them at the moment if their cities were being destroyed by regular bombs or atomic bombs. The result was still the same, a completely destroyed city. It wasn't until they found out how effective the weapon was that they decided to surrender, even then many hard liners in the Japanese military wanted to continue the war.

After Napoleon's domination of Europe from around 1800 to 1814, the rulers of Europe wanted to insure that no one would ever be able to come so close to taking over all of Europe again. To this end, the diplomats from all of the Great Powers met at the Congress of Vienna to negotiate from 1814 to 1815. There they reorganized European boundaries in hopes of creating a stable Europe where coalitions of nations could always ally to defeat one nation that got out of hand.
