The rivalry dates to 1899 in the
Arizona Territory, when the University of Arizona in
Tucson played the Normal School of Arizona of
Tempe – which later evolved into Arizona State University – as part of the Arizona Territorial Football League Championship. (Arizona, as well as New Mexico, achieved statehood in 1912.) The championship was a four-way series that also included
Phoenix Union High School and
Phoenix Indian School. Arizona and the Normal School met on November 30, 1899, for a
Thanksgiving Day match at Carrillo Gardens in Tucson. Contemporary newspaper stories indicate that this was the first game for the university squad, while the Normal team was comparatively more experienced and better trained. The event drew 300 enthusiastic fans and was followed by a post-game Thanksgiving celebration for both teams hosted by the university. The "Normals", as they were called, won the game 11–2; as they had previously defeated the other schools, they were declared champions and received the Territorial Cup. The two teams played each other sporadically for the next decades, and have played almost every year beginning in 1925 (when Arizona State became a four-year college). The rivalry became particularly heated in the late 1950s amid the political contention over turning Arizona State College into an official university, a change opposed by the University of Arizona and many of its alumni. In 1958, the year the measure was to be put to a statewide vote, Arizona State defeated Arizona 47–0. The blowout win was a major point of pride for Arizona State, which became a university later that year. Another heated game came in 1968. The contest was expected to decide which team would go on to the
Sun Bowl, but before the game, Arizona coach
Darrell Mudra issued an ultimatum to the Sun Bowl committee that his team would not play in the bowl unless they were selected regardless of who won. The committee chose Arizona, who promptly lost to Arizona State 30–7 in what became known as the "Ultimatum Bowl"; Arizona proceeded to lose the 1968 Sun Bowl 34–10 to the Auburn Tigers. The events led to the creation of the
Fiesta Bowl as a default bowl for Arizona State should they receive no other bids. It went on to become part of the highly lucrative
Bowl Championship Series Each sport is worth either a half or full point in the year-long competition. While the series has yet to have an official sponsor like other rivalry series between two universities, both UA and ASU have tracked down and promoted the series each season. The school that records the most points during the school year wins a trophy that is named after the Territorial Cup football trophy. If both schools finished tied, the winner of the football game decides the tiebreaker and is declared the winner. As of the 2025 season, UA leads the series and is in possession of the trophy. ==Rivalry name==
