Georgia Institute of Technology
Georgia Tech students hold a heated, long and ongoing rivalry with the University of Georgia, known as Clean, Old-Fashioned Hate. The first known hostilities between the two institutions trace back to 1891. The University of Georgia's literary magazine proclaimed UGA's colors to be "old gold, black, and crimson". Dr. Charles H. Herty, then President of the University of Georgia, felt that old gold was too similar to yellow and that it "symbolized cowardice". After the 1893 football game against Tech, Herty removed old gold as an official color. Tech would first use old gold for their uniforms, as a proverbial slap in the face to UGA, in their first unofficial football game against Auburn in 1891. Georgia Tech's school colors would henceforth be old gold and white.
Montana–Montana State football rivalry
The rivalry began in 1897, making it the 31st oldest in NCAA Division I and the 11th oldest west of the Mississippi River. It is also the fourth-oldest Football Championship Subdivision rivalry. Montana leads the series but that margin is 32–29, which is considerably smaller, since Montana State joined the NCAA in 1957. The game, especially of late, has major implications for the Big Sky Conference championship and its automatic bid to the Division I – FCS playoffs.
