アリゾナ・リパブリック
下積み時代
アリゾナ・リパブリックは1890年5月19日に、ザ・アリゾナ・リパブリカン（The Arizona Republican）.という名前で作られた。当時、アリゾナ・リパブリカンは人種差別主義の観点が知られていた。
それより以前も、人種差別じみた観点は知られており、特に、ネイティブアメリカンやアフリカ系アメリカ人、メキシコ系アメリカ人に対するそれは強かった。数年後、アリゾナ・リパブリカンは名前と人種観を変えた。
Dwight B. Heard, a Phoenix land and cattle baron, ran the newspaper from 1912 until his death in 1929. The paper was then run by two of its top executives, Charles Stauffer and W. Wesley Knorpp, until it was bought by midwestern newspaper magnate Eugene C. Pulliam in 1946. Stauffer and Knorpp had changed the newspaper's name to The Arizona Republic in 1930, and also had bought the rival Phoenix Evening Gazette and Phoenix Weekly Gazette, later known, respectively, as The Phoenix Gazette and the Arizona Business Gazette.
パリアム時代
GazettesとRepublicを買収したパリアムは、,1975年に86歳で亡くなるまで両方の新聞社を運営した。 A strong period of growth came under Pulliam, who imprinted the newspaper with his conservative brand of politics and his drive for civic leadership. Pulliam was considered one of the influential business leaders who created the modern Phoenix area as it is known today.
Pulliam's holding company, Central Newspapers, Inc., as led by Pulliam's widow and son, assumed operation of the Republic/Gazette family of papers upon the elder Pulliam's death. The Phoenix Gazette was closed in 1997 and its staff merged with that of the Republic. The Arizona Business Gazette is still published to this day.
1998年, a weekly section geared towards college students, "The Rep", went into circulation. Specialized content is also available in the local sections produced for many of the different cities and suburbs that make up the Phoenix metropolitan area.
ガネットの買収
Central Newspapers was purchased by Gannett in 2000, bringing it into common ownership with USA Today, the ツーソン・シチズン (the afternoon newspaper in Tucson which Gannett purchased in 1977) and the local Phoenix NBCの加盟局KPNX. The Republic often supplements its coverage of Southern Arizona with stories from the Citizen. The Republic and KPNX combine their forces to produce their common local news website, www.azcentral.com. It is the most-visited site in the state of Arizona and is among the most-trafficked newspaper websites in the U.S.
スタッフ
Notable figures include Pulitzer-prize winning cartoonist Steve Benson and columnists E.J. Montini and Laurie Roberts. One of Arizona's best-known sports writers, Norm Frauenheim, retired in 2008.
ドン・ボレスの殺人
An investigative reporter for the newspaper, Don Bolles, was the victim of a car bombing on June 2, 1976, dying eleven days afterward. He had been lured to a meeting in Phoenix in the course of work on a story and the bomb detonated as he started his car to leave. Retaliation against his pursuit of organized crime in Arizona is thought to be a motive in the murder. The case has not been solved.
