Eurabia (a portmanteau of "Europe" and "Arabia") is the name given to a hypothetical future scenario in which, thanks to a supposed declining birth rate among white Europeans and capitulation from politicians trying to appeal to immigrant communities, Europe becomes ruled by Muslims, who reshape the continent to resemble the Middle East (specifically either Saudi Arabia or Afghanistan), or at least the Theme Park Version of it. While the word itself was first used as a name for the newsletter of a Euro-Arab friendship committee in the 1970s, the concept underlying its modern usage was coined by Bat Ye'or in her 2005 book Eurabia: The Euro-Arab Axis, which claimed that there was a conspiracy underway between France and the Arab world to allow Europe to become "Islamicized" as part of a plan to increase its power against the United States and Israel.
While Ye'or's theories have been derided by a lot of academics, it has not stopped her work from inspiring a number of works imagining the Islamic takeover of Europe. Bear in mind that a lot of the mindset on this trope involves an Arab equals Muslim view, which ignores non-Muslim Arabs or non-Arab Muslims.
Usually involves a Bad Future. May be part of an Author Tract or Filibuster Freefall. Compare and contrast other region-specific cases of Take Over the World (America Takes Over the World, Russia Takes Over the World, China Takes Over the World, Japan Takes Over the World, etc.) as well as Americasia on the other side of the Atlantic Ocean.
- In Flashback by Dan Simmons, Europe has been taken over by global caliphate.
- In Caliphate by Tom Kratman, Europe is part of a global caliphate, and only the United States is still beyond its reach.
- The Partisan, an explicitly white-supremacist novel, involves a white French woman slaughtering her way through a Paris that has been taken over by Islamists.
- Michel Houellebec's Soumission features a France electing a Muslim as president, who then proceeds to enact his radical agenda.
- L'An 330 de la Republique by Maurice Spronk (written in 1894) features a morally decadent West being taken over by a more dynamic Islamic world, in a Take That! favoring his neo-Nietzschian ideals.
- The Genie of Londonistan tells the story of a future where England has been taken over by Islamists and the protagonist is the victim of a terror attack whose consciousness has been transferred into the body of drive-by shooting victim.
- The Islamic Conquest of Europe 2020 tells the story of Europe's gradual fall into Islamism in the not-too-distant future.
- The Camp of the Saints, written in 1973, portrays France, and later the rest of Europe, being overtaken by immigrants from the third world, although in this example, the takeover originates from India, rather than the Middle East.
- The Marîd Audran series portrays a world where the West is in decline while the Arab World prospers, resulting in Islam becoming dominant.
- The Mirage is an Alternate History variant. The Middle East and North Africa are unified into the United Arab States, which went on to become a major player in world history, while Europe and America are divided among third-world Christian nations. On November 9, 2001, Christian fundamentalists hijacked planes and crashed them into important landmarks in Baghdad and Riyadh, which lead to the UAS invading the Christian States of America in 2003. Later it's revealed that the entire setting was created as a result of a wish made to a Djinn.
- In The Years of Rice and Salt, this future happens a thousand years early, as The Black Death kills off virtually the entire European population, allowing the Islamic world to settle the empty continent. The resultant power struggle over the next thousand years is between the Islamic world and the Chinese one.
- In Pamela Sargent's Venus trilogy of SF novels, primarily about the terraforming of Venus in a Colonized Solar System future, Earth is largely Muslim, although the regime isn't at all tyrannical.
- Way back in The '50s, The Chronicles of Narnia featured a constant state of tension between Narnia and Calormen. Narnia is a Magical Land patterned on Christian virtues and European folklore, while Calormen is a cruel and expansionist nation-state located in The Savage South and patterned on the Arabian Nights stories. The Last Battle, C. S. Lewis's final installment in the series, centres on a Calormene invasion of Narnia. In The '50s, there was less anxiety than there is today about Islam in Europe, so the Calormene threat draws more on the historical spectre of Moorish and Ottoman incursions into Europe centuries ago — which makes sense, considering the series's Medieval European Fantasy nature. Moreover, the polytheistic Calormene faith is closer to the Middle East's pre-Abrahamic pantheons than to Islam itself. On the other hand, Lewis does sneak in a few jabs at politically correct multiculturalism, like when Les Collaborateurs insist that the Calormene god Tash and the Narnian god Aslan are one and the same.
- In the dystopian novel The Notre Dame De Paris Mosque, Muslims take over the Western Europe, impose Shariah law over it, and shut Europeans who did not convert to Islam into ghettoes.
- In The Year 2050: America's Religious Civil War is about this scenario taking place in America, the title being a reference to the year there will supposedly be a Muslim/Arabic majority, leading to a Muslim President (though the book insists Obama already was one) and majority Congress and a Western/Christian La Résistance. The book still takes time to mention how Europe and the Middle East have formed their own Caliphates that will be subordinate to the American one.
- Without Warning has a prominent subplot about a US spy investigating a generational conspiracy to Islamicize France, with the full consent and support of the French government.
- In the "What If?'' counter-factual novel written by actual historians, one of the Alternate History scenarios describes the Battle of Tours being won by the Muslim invaders of Spain. After the defeat of the Frankish army, the Caliphate keeps bringing in more forces across the Mediterranean, ultimately conquering most of Western Europe and surrounding the Byzantine Empire on two sides, while reintroducing infrastructure and central governance absent in those areas since the Romans. When European explorers sail to the new world, they're carrying Korans, not Bibles, ultimately turning Islam into the single largest religion on Earth.
- Readily done in Crusader Kings II. Aside from player-made empires, the Umayyad Sultanate of Andalusia in 769 almost invariably takes over the remaining Christian regions of Spain and will usually expand well into France unless checked by an interested player (or Francia or the Holy Roman Empire in the rare circumstance that an AI Charlemagne manages to form them.)
- Command & Conquer: Generals: In the sequel, the totally-not Al-Qaeda GLA (which is awful lot more comparable to ISIS) manages to get control over Western Europe (thanks in part to U.S. isolationism after having their weaponry stolen and used to destroy their own forces). It's China that drives them out.
- A popular Game Mod callled Rise of the Reds postulates that the GLA invasion actually reversed the trend of the Islamisation of Europe; the European Muslims were so utterly disgusted by the GLA's chain of war crimes that they denounced anything having to do with them and subsequently tried harder than ever to integrate and accept Western values, in an attempt to escape any potential stigma they could suffer from it. This is especially true in Germany with its large Turkish minority, as it's cited as a direct example. As far as the story goes, it worked out and Islamic extremism and the GLA come out severely weakened, if sadly not fully defeated (by the assumed 2040s, the GLA has a strong foothold in mid-Africa, but not much support elsewhere).
- The Simpsons:
- Parodied in an episode where Bart befriends a Muslim family, and Homer, who'd been watching too many episodes of 24, has a nightmare about Springfield becoming Islamicized, with the Genie from Aladdin transforming American things into stereotypical Muslim things (and turning all music into copies of Cat Stevens albums).
- In another episode, "Days of Future Past", Milhouse is living in Michigan, which in the future is under shariah law, and is forced to wear a hijab.
