No not even. World War 1 or two would have to be it. Both shaped the world emmensly(sp?), much more than either of those two did. the Coldwar would be high up there, the Atomic bomb,Birmingham bus boycott, Sputnik all would be high.infact I'll actually list them in order of importance. 1. World war I.Not really the war, but the effects of the end of the war. the treaty of Versailles allowed facist to get in control in Germany, Italy and Spain.2. World war III was hardpressed not to make this tied for first, but world war I lead directly to world war II. WWII also saw the rise of the US and USSR to power.3.Cold war.We're having this conversation on the internet because of the technologies devised to kill each other in the cold war.4. Sputnik and Explorer.Often over looks are the sattalites which were sent into space starting in the 1950s. without them we never would have had all this cool electronics stuff we have now.5.Crash of 29 and the Depression.The Great Depression is an after effect of WWI, some countries experienced it immediatly following the war, others had to wait a decade. the depression saw American society change in such a way like never before. the government took a more active role in our lives, and the second great westward migration happened.6. The flu of 1919.50-100 million dead, you bet your ass thats important. it also lead to some of the first health care insitutions that we see today.7.Birmingham Bus BoycotteMoney talks, and this showed that even the poorest of groups have enough money to hurt the richest. This was also the start of the Civil Rights movement.8.The Great San Francisco EarthquakeShoke reality right into the American concensness(sp?). it also helped change our finacial institutions and began the build revolution from Wood to steel.9.African Rebellions.Colonialism ends10.United NationsNothing has screwed the world up more than this lie of an organization. eventually they will end the soverngty of every nation on Earth.
