Can someone explain why some college football rivalries are so intense?

Hey y'all, as an international student, I'm trying to understand the culture behind American college football. I've seen some games that are so heated it's like life and death. What causes these intense rivalries? What are some of the most lopsided rivalries in college football and the stories behind them?

The intensity of college football rivalries in the United States often stems from a combination of factors such as regional pride, historical disputes, and the competitive spirit of the sport itself. They are an integral part of the college experience in many American universities and often have profound cultural and social implications that extend well beyond the gridiron.

Probably one of the most intense rivalries is between the University of Michigan and Ohio State University. This rivalry, often called "The Game," dates back to the late 1800s and the intensity derives largely from the historical and geographical proximity of the two institutions. In the past, their games have decided Big Ten conference titles and even national championships.

The Alabama vs Auburn rivalry, often referred to as the "Iron Bowl," is another that is particularly heated. This rivalry represents a deep divide within the state of Alabama, with allegiances often split down family lines. The competition between these two schools is so fierce that it affects the social fabric of the state all year round, not just during football season.

Lastly, the landmark rivalry between the United States Military Academy (Army) and the United States Naval Academy (Navy) transcends the typical college football rivalry. The games reflect a friendly but intense competition within branches of the United States military, with the matchup serving as a symbol of the interservice rivalry that exists between the Army and the Navy. This rivalry has a strong tradition and is characterized by deep mutual respect.

In many cases, the rivalries are not necessarily lopsided and the balance of power can swing back and forth over the years. However, one example of a somewhat lopsided rivalry might be the one between the University of Oklahoma and Oklahoma State University, often referred to as the "Bedlam Series," where Oklahoma has a significant edge in overall wins.

The cultural significance and tradition behind these rivalries make them more than just football games - they’re events that bring communities together in competition and camaraderie, and that's what makes them so intense and enduring.
