WHAT’S IN A NAME?
“The Fighting Irish nickname was first coined for the Irish immigrant soldiers who fought for the Union during the Civil War in what became called the Irish Brigade, including three regiments from New York. Their valor was later memorialized in the poetry of Joyce Kilmer. That’s also the Irish way: Ireland’s poetry is often better than its fighting, turning defeat into eternal glory. The University has a valid claim to the nickname because the brigade’s beloved chaplain was Rev. William Corby, C.S.C., who later became the third president of Notre Dame.”
