The Ten Year War was a series of college football games, played from 1969 to 1978, in the Michigan–Ohio State football rivalry that pitted coach Woody Hayes of the Ohio State Buckeyes against coach Bo Schembechler of the Michigan Wolverines. In most contests, the Big Ten conference championship and a trip to the Rose Bowl were at stake, and in some cases, a possible national championship.
