It began in 1889, one of the oldest in Fighting Irish football annals. It has been suggested that the nickname, "Fighting Irish," originated during that first meeting when Northwestern fans chanted, "Kill those Irish! Kill those fighting Irish!" at halftime. Northwestern and Notre Dame had a yearly contest from 1929 to 1948, with the winner taking home a shillelagh, much like the winner of the Notre Dame–USC contest now receives. The Northwestern-Notre Dame shillelagh was largely forgotten by the early 1960s. Northwestern ended the series after 1948, as did several other schools who were getting tired of being beaten year in and year out by Notre Dame, and the two schools would not meet again until 1959. By then, Ara Parseghian was coaching the Wildcats, who notched four consecutive victories over Notre Dame between 1959 and 1962. After Ara came to Notre Dame, he posted a 9–0 docket against his old team. In fact, the Fighting Irish did not lose to Northwestern again until September 1995, which was the beginning of a Rose Bowl season for the Wildcats and the two teams' last meeting for nearly 20 years. The series was renewed in 2014 when the Wildcats traveled to South Bend for the first time since 1995, defeating the Irish 43–40 in overtime. The Irish repaid the visit in 2018 when they traveled to Evanston and defeated Wildcats 31–21. Notre Dame leads the series 38–9–2.
