IYO What are the 3 Most Important fights in History?

In your opinion, what are the 3 Most Important boxing fights in History? When picking them consider their significance to the history of boxing, the general public/world history. List them and why. Mine may be subject to change depending on what others post but here is what I have at the moment: 1. Muhammad Ali -vs-Joe Frazier 1. This fight became so intertwined with current politics at the time that in many ways it became much more important than a mere sporting event. In addition, the fight actually lived up to the hype. 2. Joe Louis -vs- Max Schmeling 2. Once again this fight came to represent more than two pugs in a ring. It was the United States -vs- the Nazis. 3. Marvin Hagler -vs- Tommy Hearns. This fight didn't serve to have any non-boxing historical relevance but it ultimately became the battle that all great fights would be compared to. I'm sure the third could be replaced Corbett/Sullivan.. Ok, what does everyone else have?
