* UsefulNotes/{{Chicago}} and UsefulNotes/NewYorkCity. UsefulNotes/{{Boston}} and New York as well.

* Creator/{{Marvel}} vs. Creator/DCComics!

* Creator/AbigailBreslin and Creator/ChloeMoretz

* Creator/JoanFontaine vs. Creator/OliviaDeHavilland. Rival Golden Age movie stars who fought over Oscars, [[TheGloriousWarOfSisterlyRivalry they are rival sisters to boot]]. Both of them remained spiteful up until Fontaine's death in 2013.

* Creator/ArnoldSchwarzenegger and Creator/SylvesterStallone, though it's more of a FriendlyRivalry since both are good friends and have co-starred each other in ''Film/TheExpendables'' films.

* Creator/BorisKarloff and Creator/BelaLugosi are alleged to have had a pretty bitter rivalry. It's supposed to have started when Bela turned down the role of the Frankenstein monster for being "undignified", only for Karloff to win national acclaim for taking the role. Karloff went on to repeatedly upstage Bela while the latter's career went increasingly downhill.

* Creator/NormanMailer and Creator/GoreVidal shared a life-long rivalry. One time the encounter between them turned physical and Mailer punched out Vidal on the floor. Vidal had the last laugh however, by saying: "Words fail Norman Mailer yet again."

* Creator/LillianHellman vs. Mary Mccarthy.

* Creator/WaltDisney and Creator/MaxAndDaveFleischer. The Fleischers were ''the'' studio in the 1920's and worked on many innovations like synchronized sound and three-dimensional backgrounds that Disney perfected and got credit for. Disney, located in Hollywood favored realism, while the Fleischers located in New York City preferred surrealism. Eventually the Fleischer films suffered because not only was Disney able to lure away key talent because as film historian Leonard Maltin said "Fleischers' interests were mechanical not artistic", but only because their distributor Paramount forced them to start imitating Disney. In the end the Fleischers lost their studio because of poor business decisions like moving their studio to Miami, Florida which in 1930's was a backwater town away from the talent hub of NYC which was financed entirely from a loan from Paramout. The failures of the Fletchers' feature-films meant they couldn't pay back the loan and Paramout ousted the brothers and took control of their studio. By contrast Disney made sure he was in control of his studios, not his distributors he had three: Pat Powers, United Artists, and RKO before he decided to do it himself. He also had the benefit of having his brother Roy to act has his business savvy partner to take care of financing from the Bank of America.

* Creator/MattGroening (''WesternAnimation/TheSimpsons''), Creator/TreyParker & Creator/MattStone (''WesternAnimation/SouthPark'') and Creator/SethMacFarlane (''WesternAnimation/FamilyGuy'') are all each others' rivals, though they do show some respect at times for each others' work. Between ''South Park'' and ''Family Guy'', however, the rivalry is very bitter.
* Creator/{{Herge}} (''Franchise/{{Tintin}}'') felt threatened by the succes of Creator/ReneGoscinny and Albert Uderzo's ''ComicBook/{{Asterix}}''. In terms of commercial and artistic succes they were certainly equals. Though Hergé did provide a shout-out to Asterix in his final album ''Tintin and the Picaros'' where a man dressed like the Gaulish warrior can be seen in the crowd. Goscinny and Uderzo returned the nod by having Thompson and Thomson have a cameo in ''Asterix in Belgium'', which ironically would also turn out to be the final Asterix album for Goscinny who died during the making of the album.

* Coca Cola and Pepsi
* Playboy and Hustler

* The Polish computer game magazines ''[[Magazine/TopSecretMagazine Top Secret]]'' and ''Secret Service''. The latter was made up of the old ''Top Secret'' personnel who all left in 1993 to [[StartMyOwn start their own mag]]. Both magazines occasionally put in very thinly veiled {{Take That}}s at each other.

* UsefulNotes/McDonalds vs. UsefulNotes/BurgerKing.

* UsefulNotes/{{Michigan}} and UsefulNotes/{{Ohio}}. Both states are still a little miffed over [[UsefulNotes/ToledoOhio Toledo]].

* The University of Oxford and The University of Cambridge, ever since the 13th-century, most famously manifests in the annual boat race between the two schools.

* Across the ocean, there's Yale and Harvard in America and Queen's and [=McGill=] in Canada. Also, And MIT and Caltech.

* Music/FrankZappa and Music/CaptainBeefheart. Childhood friends who both gained a reputation for making groundbreaking bizarre avantgarde music. It was Zappa himself who started off Beefheart's career by having him record his voice in his studio. Beefheart tried his own career, but by 1969 he felt disillusioned about the ExecutiveMeddling and lack of album sales. Zappa produced his next album ''Music/TroutMaskReplica'' and gave him total creative freedom, but the record hardly sold and Beefheart blamed Zappa for this. For years they remained bitter towards each other until Beefheart found himself broke and contractually unable to record anything. Zappa took him up for the ''Music/BongoFury'' (1975) tour, until they once again had a falling out. Only when Zappa fell terminally ill with cancer in the 1990s did the two friends reconcile.

* Most political parties are each others' rivals.
* During the Cold War the U.S.A and U.S.S.R. were each other rivals.

* Two Canadian Fathers of Conferederation, George Brown and John A. Macdonald, were rivals. Brown, the founder of the ''Globe and Mail'', was much fiercer in the rivalry; his quest for power was ultimately fruitless (in other words, he was [[KickedUpstairs appointed a member of the Senate]]), whereas Macdonald was knighted and served as Prime Minister for 19 years. Brown got a college named after him, though. (One of the reasons Brown didn't succeed, though, was that he wasn't given the chance: he was assassinated.)
* A number of leaders of the Liberal and Conservative parties of Canada fall into this trope, most famously John G. Diefenbaker (Conservative leader 1956-67, PM 1957-63) and Lester B. Pearson (Liberal leader 1958-68, PM 1963-68). The two men were extremely intelligent, accomplishished individuals who were able to be civil to one another.

* Pierre Trudeau (prime minister of Canada, and also father of the current PM Justin Trudeau) vs. René Lévesque (leader of Parti Québécois, a mainstream political party advocating for the separation of Quebec). The duo fought bitterly over ten years over the independence of Quebec. The rivalry culminated during the drafting of the Canadian constitution; Trudeau, fearing the trouble Lévesque might cause, had to trick Lévesque by waiting until he was asleep before starting the backroom deals that would ultimately produce the document. Lévesque and the province of Quebec never forgave the trick; they still have not signed the constitution.

* It's often joked, though with much substance, that the true bitterest enemies and rival Generals of World War Two, were General George Patton and Field Marshal Bernard Montgomery.

* UsefulNotes/CharlesDeGaulle and [[UsefulNotes/ThePresidentsOfFrance Francois Mitterand]] are the two men most responsible for defining postwar France. They were also ideological opposites, with De Gaulle on the center-right and Mitterand on the left. While De Gaulle defeated Mitterand in the 1965 national election, Mitterand outlived De Gaulle and went on to be France's longest-serving President.

In the end the Fleischers lost their studio because of poor business decisions like moving their studio to Miami, Flordia which in 1930's was a backwater town away from the talent hub of NYC which was financed entirely from a loan from Paramout. The failures of the Fletchers' feature-films meant they couldn't pay back the loan and Paramout ousted the brothers and took control of their studio.

* Italy and UsefulNotes/{{Yugoslavia}}, the latter replaced by UsefulNotes/{{Slovenia}} and UsefulNotes/{{Croatia}} after [[UsefulNotes/TheYugoslavWars the break-up]], due various events happened between 1918 and 1960 [[Administrivia/RuleOfCautiousEditingJudgment on which is better not to elaborate here]].

* The Polish computer game magazines Magazine/TopSecret and Secret Service. The latter was made up of the old Top Secret personnel who all went and left back in 1993 to [[StartMyOwn start their own mag]]. These were the old days of videogame journalism, when they still could pepper their issues with very thinly veiled {{Take That}}s at each other.

* Willy Vandersteen (''ComicBook/SuskeEnWiske'') and Marc Sleen (''ComicStrip/{{Nero}}''). Both were the best known and commercially best-selling comic strip artists in Flanders from the 1940s until the 1960s. After 1965 however Vandersteen soon eclipsed him because he had several succesful series in syndication, drawn by his studio which also sold well in other countries, especially the Netherlands. Sleen on the other hand had dropped all his other series in favor of ''Nero'' because he had to do all the work alone. His comics only sold well in Flanders, though they had some cult succes in Wallony and the Netherlands too, but his stories became less interesting for children, while he refused to ''sell out'' which made his series only sell well among adults from that point on.

* Creator/EiichiroOda (''Manga/OnePiece'') and Creator/MasashiKishimoto (''Manga/{{Naruto}}''). Though it's very much a FriendlyRivalry, and they respect each other's work.

* Pioneer paleontologists Othniel Charles Marsh and Edward Drinker Cope. In their case, it got ugly.

* Ike Perlmutter and Kevin Feige who happen to work for the same company Marvel. Perlmutter runs Marvel Entertainment overall, while Feige is in charge of Marvel Studios. Perlmutter was known for dismissing Feige's ideas for films like ''Film/{{Black Panther|2018}}'' and ''Film/{{Captain Marvel|2019}}'' in favor of his own -- specifically an ''Inhumans'' movie. It got to the point, where Feige got fed up with Perlmutter and eventually complained about it to Disney who restructured the company so Feige would report directly to them, bypassing Perlmutter completely. In response, Feige dropped plans for the ''Inhumans'' film, so Perlmutter responded by pushing for an ''Inhumans'' TV show since he still sway over the TV division. The result was that ''Series/{{Inhumans}}'' was massive flop with critics and viewers, while ''Black Panther'' and ''Captain Marvel'' became the one of the most successful Marvel movies, each making over $1BN worldwide.

* Music/FrankSinatra and with Music/BingCrosby used to trade insults over live radio broadcasts. When JFK snubbed Frank's campaign support and cancelled a visit to his house, choosing to make a public appearance with Bing instead, Frankie flew into a rage and severed any ties to Kennedy or the entire Democratic Party.

* UsefulNotes/OttoVonBismarck vs Ludwig Windhorst (leader of the German Centre Party). Windhorst was by far the ablest and most dangerous critic of Bismarck's policy. The iron chancellor said once:"Everyone must have someone to love and someone to hate. I have my wife to love and Windhorst to hate."
