Pairs of schools, colleges and universities, especially when they are close to each other either geographically or in their areas of specialization, often establish a college rivalry with each other over the years. This rivalry can extend to both academics and athletics, the latter being typically more well-known to the general public. These schools place an added emphasis on emerging victorious in any event that includes their rival. This may include the creation of a special trophy or other commemoration of the event. While many of these rivalries have arisen spontaneously, some have been created by college officials in efforts to sell more tickets and support their programs. The largest and most bitter rivalry is the Michigan-Ohio State rivalry.
