Exactly where and how Notre Dame's athletic nickname, "Fighting Irish," originated never has been perfectly explained.

One story suggests the moniker was born in 1899 with Notre Dame leading Northwestern 5-0 at halftime of a game in Evanston, Ill. The Wildcat fans supposedly began to chant, "Kill the Fighting Irish, kill the Fighting Irish," as the second half opened.

Another tale has the nickname originating at halftime of the Notre Dame-Michigan game in 1909. With his team trailing, one Notre Dame player yelled to his teammates - who happened to have names like Dolan, Kelly, Glynn, Duffy and Ryan - "What's the matter with you guys? You're all Irish and you're not fighting worth a lick."

Notre Dame came back to win the game and press, after overhearing the remark, reported the game as a victory for the "Fighting Irish". The most generally accepted explanation is that the press coined the nickname as a characterization of Notre Dame athletic teams, their never-say-die fighting spirit and the Irish qualities of grit, determination and tenacity".
