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.
Wisła Kraków
The term "Holy War" refers to the intense rivalry between the two Kraków-based teams; Wisła and KS Cracovia. In 1906, the establishment of the two first Polish football clubs, Cracovia and Wisła, created a rivalry that now dates back more than 100 years. The term "Holy War" was first used to describe the rivalry of Kraków's Jewish teams, Makabbi and Jutrzenka. A Jutrzenka defender, Ludwik Gintel, who later joined the Cracovia side referred to the derby match against Wisła as the "Holy War". The phrase was incorporated into a song and has since been popular amongst both Wisła and Cracovia fans.
