One of the absolute best things about pro wrestling, and especially WWE, is the memorable feuds that they have given us through the years. There is nothing quite like seeing two people battle for supremacy, evenly matched as they fight and claw their way to the top. Sometimes the feud has to do with a title belt, and other times, it's simply a "blood feud" between people who hate each other and want to eradicate one another from the company. Feuds are the cornerstone of WWE's rise to where they are today. You can have all the legendary names and wrestlers you want, but if they don't have someone to feud with, and someone to play off of, it's going to be for naught. Today, we'll be looking at ten of the biggest, best, and most influential feuds in company history. Feuds that created legends. Feuds that helped to build the company and take them to another level. Feuds that changed the way other companies promote their product. Most of them feature competitors that waged war for years, battling on numerous occasions, and sometimes crossing the face/heel line somewhere in between. These are ten of the feuds that you can point to when you want to talk about what made WWE what it is today.
