"Those who cannot remember the past are condemned to repeat it."
— George Santayana
Often a show will have a situation that is repetition of something that happened previously within the show history. Almost always used as either a Running Gag or tragically.
There are some films where they deal with the world repeating over and over, e.g. Groundhog Day, the similar film 12:01, and the Eternal Recurrence phenomenon. But this trope happens when history repeats itself without a "Groundhog Day" Loop.
A common example will be for a show about kids to have the children experience something, and then have the adults in the show respond by reminiscing about when the exact same thing happened to them at that age. Sometimes there is a flashback. If the adults are the main characters and the same thing occurs, this becomes Generation Xerox.
Or it can happen in an adult show where the characters have had flashbacks to show some of the older characters' backstories, and then you have an episode that focuses on the younger characters who experienced the same thing.
Can also be used just with a character repeating the exact same experience as another character did previously (sometimes in an earlier episode). The new victim might have boasted about how much better he would have handled it, expect an Aesop on how we should be less critical of "The Man in The Arena". Or he might just handle it perfectly, making the first victim hate him even more.
Can be used to justify (or subvert) Genre Savvy characters.
When it applies only to a Stock Phrase it's probably an Ironic Echo. See also Here We Go Again.
Love Hina has parallel scenes at the beginning of the series and the beginning of the epilogue.
In the past, Chrono of Chrono Crusade (the manga version) was in love with a woman called Mary Magdalene, who was possessed by Pandaemonium, the demon's Hive Queen. This kicked off the events which led to her death. When Rosette is placed in a frighteningly similar situation, Aion feels the need to point out that history is repeating itself.
The Gundam series, according to ∀ Gundam, is all one timeline with this going on. Mankind keeps making space colonies, having a civil war with them, getting a bit too violent and inventing gundams that are too powerful, and destroying said colonies, forgetting about it, then sending out new colonies, only to have a civil war with them. Then gundams get too powerful... and each time, they progress a little further, with the destruction and casting back of mankind going further each time. By the time of ∀ Gundam, they're at an early-1900s level of technology. And history repeats again anyway, using Lost Technology.
This is also specifically the point of the ideological debate in Mobile Suit Gundam Wing's movie, Endless Waltz. The villainess argues that war is an inevitable part of human nature (the titular "endless waltz" of war, peace, and revolution), while the female lead says that lasting peace can happen if people are willing to put forth the effort to end the Vicious Cycle. Needless to say, at least in the ∀ Gundam version of events, she does't succeed in spreading that idea.
Mobile Suit Gundam Unicorn applies this to the Universal Century in general. Despite all the lofty aspirations made by humanity, from uniting Earth under the Federation to the space colonies and even the Newtype ideal, the same mistakes they've supposedly overcome keep getting repeated...albeit on a much larger scale as shown by the One Year War and subsequent conflicts. Audrey wonders at one point whether an answer to that age-old question even exists.
In Code Geass, Lelouch lost his mother to an assassin, which shattered his cozy, comfortable worldview and inspired him to change the world with Well Intentioned Extremism in order to give his beloved sister a better life. His father the Emperor, who is the biggest obstacle on his quest, went through pretty much the exact same thing in his lifetime and is himself trying to change the world — along with his wife, who's Not Quite Dead. You can imagine Lelouch's shock when he learns all this...
Maison Ikkoku has an example where Kyoko romantically pursued her teacher, and when Godai gets a teaching job at her old school not only is he also romantically pursed by a student, but the several of the methods used are very similar. (Tagging the teacher with a heart on the back when he's not looking).
In Magic Knight Rayearth, High Priest Zagato fell in love with Emeraude, the Pillar of Cephiro. Zagato's younger (and identical) brother Lantis would also fall in love with the girl who would become the Pillar, Hikaru. The irony is not lost on either.
The Moon and Earth Kingdoms from Sailor Moon where originally destroyed by Princess Serenity and Prince Endymion's forbidden love. When they are resurrected (as Usagi and Mamoru respectively), they fall in love again and history is doomed to repeat unless they take actions about it. This is taken further in the live action adaptation.
Geo-Force tries this gambit against Deathstroke in Final Crisis: Last Will and Testament by luring him to the location where Deathstroke's son had his throat slit. Deathstroke claims that Brion isn't the first one to try this, but Brion is the first to slit his own throat for full effect.
In 2099: Manifest Destiny, we find out Captain America's fate: he once again ended up in a block of ice as the end of the Heroic Age as he'd done at the end of World War II and is revived in the 2099 time period. Amusingly, during the "One Nation Under Doom" event, a clone of Steve Rogers created to be a puppet had this as a cover story.
In The Trial Of The Flash, Reverse-Flash invokes this by planning to kill Fiona in the same way he killed Iris.
In Mega Man Reawakened, both Protoman and Roll run away because they don't want Dr. Light to fix them at first, though Roll later relents.
Robert points this out to Quentin Emerald, who's a terrorist like his father.
Back to the Future, anyone? Just one example - the skateboard chase in 1955 in Part I, the Hover Board chase in 2015 in Part II, and the horseback chase in 1885 in Part III. All involving Marty McFly being chased by a Tannen.
Notably, though, they all work out entirely differently. The first time, Marty easily beats them because he's the only one with a skateboard. The second time, they've all got hoverboards, in fact, they've got better hoverboards, and he narrowly escapes them. The third time, they're all on horseback, and he's on foot, and they catch him easily.
Lampshaded by old Biff in 2015: "There's something very familiar about all this."
This is actually one particularly bleak interpretation of the events seen in John Carpenter's The Thing (1982). The theory here is that the alien spaceship that brought the Thing was deliberately crashed in Antarctica in order to keep it from getting out. Fast forward 100,000 years later and a group of Norwegians find it, examine it, and then it gets out and kills all but two who end up dying in the process of trying to keep it from getting further. Then the remainder of an American expedition destroyed by the Thing destroys their camp in an effort to keep the Thing from being found by a rescue team- whether they succeed is left for the viewer to decide, but an alternate ending shown in some TV broadcasts implied that it escaped
German philosopher Oswald Spengler claimed in his non-fiction book The Decline of the West that this happens in every major culture: A culture emerges among until then barbarian people, fuses them together to nations. The great myths, art styles and religions develop. At the beginning, strong kings rule, but their power soon is weakened by their noble vassals. A great movement reforms the religion. Meanwhile, in the cities a somewhat-privileged middle class has risen, replacing feudalism economy slowly but steadily by capitalism. By cooperating with them, the crown can weaken nobility and the church, forming an absolutist state. Science and capitalism develop further, and an enlightened philosophy spreads, weakening the hold of religion. Then, the middle class will decide to get rid of the old system, usually in the form of a revolution - which starts civilization. This marks the fall of the culture - wars will get worse and worse (Napoleonic Wars -> American Civil War -> World War One -> World War II), art will become more and more offensive, and capitalism runs rampant (not without provoking counter movements). At the end, one state will conquer/control all other states, and one man will rise to the top of this state - voila, The Empire.
In A Canticle for Leibowitz, the readers know the world had had a great nuclear sometime in the past (our present). Then there's The Simplification, which is another world-wide war, and a third war (nuclear again) in the third part. The book ends with what's left of humanity moving on to a new planet, to probably keep the cycle of stupidity going.
Indeed, cherished by the Mallorean. Due to a mistake in the fabric of the universe, events recur with minor changes throughout history. By the end of the series, the heroes are actively noticing the recursion and using it to their advantage. The ultimate goal of the series is to fix this, so that time can finally move ahead.
In The Wave, a High School history teacher is trying to show his class just how easily the Nazis came to power, only to be met with disbelief by students who think that "it can't happen here." So he shows them otherwise by starting a fascist movement in the class.
Played with in ''Tomorrow Town"; the story is set in a camp of futurists who are deeply contemptuous of past and those who they see as trapped within it, but find themselves repeating certain historical patterns about how society develops and people interact within them without even realizing it. Furthermore, their efforts to predict the future are inept at best and doomed to failure. Just as the past will repeat itself, the future can't be forced no matter how hard you try.
Live Action TV
In Third Watch, Ty's father is murdered years before the series starts. His partner Sully finds out the truth behind the murder (that the murderer was paid by a corrupt cop, CT Finney) but says nothing in order to protect Ty's family's police pension. Fast forward to 2004, where CT Finney is exposed and commits suicide. Ty ends up helping Finney's son to make it look like an accident - so that Mrs Finney can still get her police pension.
In the series finale of HBO's The Wire, several characters end up in situations that harken back to the pilot episode (in tandem with Call Backs). Most notably, Detective Leander Sydnor goes to Judge Phelan and asks with his help investigating a major case (which Detective Jimmy McNulty did, in a conversation with the exact same character, five seasons prior). The "Where Are They Now?" Epilogue insinuates that Baltimore is a cyclical place, and that characters will always end up in certain roles (e.g. Michael becomes the new Omar, Dukie becomes the new Bubbles, etc).
On a more positive note, the formerly irresponsible Carver is implied to be on his way to becoming the new Daniels.
LOST starting in the season 5 finale. Its implied that people have been coming to the island only to be wiped out over and over again as part of Jacob and the Man in Black's grand morality test. Taken to an extreme in "Across the Sea" where it's revealed that Jacob isn't even the original protector of the island and that there had probably been many previous protectors before he was born.
Obligatory Buffy example: a rather dark example comes from Consequences, where Faith had accidentally killed a human, tries to dispose of the body, then becomes a rapist (damn near enough in Xander's case, then using Buffy's body to seduce Riley.) In Dead Things Buffy has essentially raped Spike, then she thinks she killed a human and Spike tries to dispose of the evidence. The way she's acting bothers her so much she looks into whether she Came Back Wrong, then she finds out she didn't.
History Never Repeats by Split Enz sounds like it will be an aversion. It's actually the singer trying to convince himself of the aversion.
The Tales of Phantasia and Tales of Symphonia time line has this going on. Periodically, mankind invents magitechnology, culminating in a Mana Cannon, the use of which kills large numbers of people and depletes so much mana as to threaten the life of the Mana Tree. Things progress too far, the Mana Cannon causes too much destruction, and civilization is cast back into the Dark Ages for a while. Then somebody starts exploring ruins, and finding out about this thing called "magitechnology"...
The Ninja Warriors Again: The game's ending explicitly says that because history repeats, the new government you were fighting for will eventually become as bad as the one you overthrew.
History Repeats: Massively in Gunstar Superheroes, which is a sequel which covers the events of the original game happening again in the distant future.
Seen in Warcraft 3 and World of Warcraft with Grom and Garrosh Hellscream. Grom was the first orc to drink Mannoroth's blood, cursing nearly his entire race with an endless bloodlust and enslaving them to the Burning Legion, all for the sake of more strength. Faced with defeat at the hands of Cenarius, Grom drank from a fountain that he believed would grant him strength, only to learn it was in fact filled with Mannoroth's blood, completely enslaving him and his clan to the demon. Years later Garrosh tried to use the Sha and then the heart of Y'shaarj to empower himself and his True Horde.
In The Legend of Zelda: A Link Between Worlds, Lorule started to gradually crumble away after they destroyed their Triforce. Ravio kicks Hilda into a Heel Realization after telling her that taking Hyrule's Triforce away from them would simply cause them to go through the same decay that is now affecting Lorule.
Somehow, SEGA has this happen to it repeatedly as far as public reception and sales numbers go. At least three points in its history, SEGA found itself in a position of dominance. Then, as time goes by, the people at SEGA grow complacent and their quality slips, but it still gets good sales due to brand recognition. People realizing the company's products are becoming shoddy and broken eventually catch up to the company, ruining its reputation, and SEGA is forced to go through major corporate restructuring, only to return back to dominance some time later. The two cycles most familiar to gamers are the period between the 16-bit era and the Dreamcast, where SEGA had to become a 3rd-party developer; and the period between it becoming 3rd-party and the present. There was also a cycle long before this, between 1971 and 1978, when SEGA suffered this via its pinball division: Because the quality was on par with American and European machines at the time and cost less to buy and to play because they were made domestically, SEGA was the force in Japanese pinball. As time went on though, the machines broke down and no one knew how to repair them with SEGA providing no real support. By 1976, SEGA's pinball sales plummeted and it had to leave the market two years later with thousands of broken, unplayable pinball machines in its wake.
In Thunder Force V's bad ending, the Guardian begs Cenes to self-destruct her ship, the Vambrace, which is a Sealed Evil in a Can like its predecessor, the Vasteel, warning her that the Vambrace has the potential to cause the same degree of global catastrophe as Vasteel did and that "the tragedy of Vasteel" will repeat. It is implied that this trope happens, as the Vambrace is too crippled to self-destruct.
Used so often in Homestuck that the concept is almost weaponized by the various textual and visual callbacks. Many of these instances, such as stairs, are subject to memery both in-story and out.
Cartoon Network 's Toonami block. When it first premiered, it had limited animation for its CGI hosts, limited budgets to aquire new shows, and suffered tremendously in the ratings departments. It also started to see this pattern again, but due to the parent network's decision to fill the block with constant reruns and only new episodes of the infamous pre-ShippudenNaruto filler arcs. When it came back, Toonami had the same amount of viewership it did in the beginning, very few new ad bumpers, only twonew shows, and most of its block consistingofold[adult swim] anime on a constant repeat.
Cartoon Planet was cancelled after 22 episodes in its original run. For Cartoon Network's 20th anniversary, a modern version of Cartoon Planet was brought back, only to once again be removed from the schedule after 22 episodes. However, it came back just in time for the actual month of the anniversary, and has remained on the schedule ever since.
In the South Park episode "Fingerbang," Stan gets a nasty reaction from his father Randy when he and his friends decide to start a boy band, and Randy opposes it vehemently throughout the whole episode. It turns out Randy was afraid that this trope would happen—he has previously been in a boy band, and while they enjoyed success at first, his life, and those of his bandmates', spiraled into total despair when the fad for them had passed. Luckily, Stan and the others bailed out before anything bad could happen.
Adventure Time: The end of "Lemonhope" implies that the Land of Ooo will eventually destroy itself just like humanity did.
Wakfu: When Adamai is horrified by Qilby's plan to drain the World of Twelve of its wakfu to power up the Zinit for another trip to the cosmos, Qilby is not surprised. He claims that Adamai and Yugo have not changed since their previous incarnations. As much as he wishes things would be different this time, his long immortal existence has taught him that history repeats endlessly.
Hitler just never learned from Napoleon's mistakes when he tried to conquer Russia. The Nazis ended up meeting the same outcome of this attempted invasion as did Napoleon's army.
