When the world collapses, the most extreme post societies spring up from the ashes, each with its own quirks and survival strategies. Below you’ll meet ten of the most memorable examples.
Extreme Post‑Apocalyptic Societies Explored
1 The Brotherhood Of Steel Fallout
Formed just before the Great War, the Brotherhood of Steel was founded on the conviction that humanity cannot be trusted with advanced technology. Its founder, Roger Maxson, witnessed the horrors of biological weapons being tested on prisoners of war and decided a disciplined order was needed to keep dangerous tech out of the wrong hands.
Over two centuries and across the whole continent of North America, the Brotherhood has morphed into a quasi‑knightly order. At its best, it protects vulnerable settlers from mutant threats that would otherwise overwhelm them. At its worst, it behaves like a gang of laser‑armed bullies, raiding anyone who refuses to hand over their computers or power armor.
The organization models itself after a medieval chivalric order, complete with knights, scribes, and paladins—though swords are noticeably scarce. Some chapters open their doors to outsiders, but most prefer to fire on sight and keep their members hidden deep underground. Their playbook includes launching tactical nukes, disappearing into bunkers, or simply waiting until everyone else dies.
Despite its lofty goal of preventing another apocalypse, the Brotherhood has a nasty habit of committing genocide against peaceful mutants and villagers who won’t surrender their tech. On the bright side, its armor and power armor outfits are undeniably cool.
2 The Many Mothers Mad Max: Fury Road
Long ago the Vuvalini—known as the Many Mothers—thrived in the Green Place, a lush oasis in the middle of the radioactive Australian Outback. Their society was female‑driven, with motherhood at the core of their mission to keep the world green.
When the Green Place turned barren, their numbers dwindled and they were forced onto the desert road, becoming the raiders we see in the film. One Mother even confesses she has killed everyone she met in the wasteland, a stark reminder that even peaceful societies can devolve into violence when survival is on the line.
Their story shows how a once‑prosperous community can be pushed into the same brutal cycle as the rest of the wasteland when the environment collapses.
3 The Tree People The 100
After a nuclear cataclysm, the Tree People took refuge in the forests that once covered Virginia. Harassed by the technologically superior Mountain Men, they reverted to muscle‑powered weapons—swords, bows, and homemade spears.
Their legal code is brutally strict: thieves are banished, traitors are executed by fire or a thousand cuts. This harsh system binds the community together, turning every member into a hardened warrior. Even children are apprenticed to veterans, earning ritual scars for each kill.
In a world where every bite of food can be contested, the Tree People embody the idea that survival often means becoming what you must be.
4 The Citadel Mad Max: Fury Road
The Citadel, ruled by the tyrant Immortan Joe, is a massive aquifer‑turned‑city perched atop a desert oasis. Admission isn’t a matter of invitation; you must satisfy a need—whether you’re a War Boy, a Black Thumb, a Blood Bag donor, a Milk Mother, or one of the Five Wives.
Every resource is harvested to the last drop: War Boys fight in road wars, Black Thumbs keep the vehicles running, Blood Bags supply healthy blood, Milk Mothers produce calcium‑rich milk, and the Five Wives serve as breeding stock. Nothing is wasted in this harsh landscape.Unfortunately, women occupy the lowest rung, reduced to slaves or imprisoned wives, illustrating how scarcity can amplify gender oppression.
5 The Sorrows Fallout: New Vegas
The Sorrows began as a band of children who stumbled into Zion National Valley decades after the Great War. An old hermit living in nearby caves tended to them—leaving books, food, medicine, and notes signed by “the Father.”
Generations later the Sorrows live peacefully, following the Father’s supposed wishes: kindness and non‑violence. They treat the caves as sacred, believing that the Father—a god‑like spirit—will punish anyone who enters.
In reality, those caves are safe houses rigged with booby traps, which is why many who venture inside never return. The Father has long since died, but the myth persists, showing how superstition can take root in a post‑apocalyptic world.
6 The Ark The 100
When the world burned itself to ash, a handful of survivors stayed safe aboard space stations. Their mission: return to Earth and restart humanity by forming the Ark.
Life on the Ark is brutal. Oxygen, food, water, and medicine must be meticulously conserved, and any crime committed by anyone over eighteen is a capital offense. Even stealing medicine for a sick child results in the death penalty.
The community’s harshness mirrors the unforgiving conditions of space—every resource is precious, and the rule of law is absolute.
7 Corvallis The Postman
Corvallis resembles a twisted version of Oz. Instead of a wizard, the town relies on a supercomputer named Cyclops to manipulate nearby settlements in the scenic Willamette Valley.When the Doomwar’s EMPs fried the circuitry, Cyclops died, but the townsfolk kept believing it was alive, using its “wisdom” to settle disputes. Our plucky hero uncovers the truth but stays silent, sparking a trading pact that unites the valley under a single Oregonian government ready to push back invading forces.
8 Fort Repose Alas, Babylon
Fort Repose started as a typical Florida beach town—sunbathers, kids playing, the whole shebang—until a nuclear clash with Russia turned a lazy afternoon into a nightmare. Society crumbled, and chaos reigned.
A veteran named Randy rallied the army reserves, establishing order by publicly hanging criminals to deter theft and murder. The community quickly adapted: they stored radioactive jewelry, shared housing, food, and water, and even organized a march to a nearby salt beach to cure a sudden salt deficiency.
While not as eccentric as other groups, Fort Repose demonstrates how quickly people can invent new institutions to meet emergent needs.
9 Crakers Oryx And Crake
After a biological disaster ravaged an already‑crippled world, a gentle, vegetarian community emerged on the coast. The narrator calls its members “Crakers,” but they’re anything but ordinary humans.
Genetically engineered by the same man—Crake—who caused the apocalypse, the Crakers can subsist entirely on grass and possess, oddly enough, luminous penises. Their sole guide is Snowman, a cynical prophet who survived the old world and was close friends with Crake.
Snowman convinces the Crakers that a god named Crake created them, bestowing rudimentary laws that quickly morph into superstition. Their dependence on Snowman is so intense that when he disappears for a few days, they burn his effigy and beg Crake for his return.
10 New California Republic Fallout
Spanning three games in the Fallout series (1, 2, and New Vegas), the New California Republic (NCR) clings to the pre‑apocalypse ideals of rule of law, democracy, safety, and freedom. It began as a tiny federation of towns banding together against mutants and raiders, enforcing a vision of civilization on a barren desert.
Less than a century after its 2189 founding, the NCR controls much of the former American Southwest, stretching toward Oregon and Baja California. As its population swelled, it sent expeditions westward in search of clean water and arable land, only to become entangled in a bloody war over New Vegas and the nearby Hoover Dam.
That very scramble for resources mirrors the very cause of the nuclear apocalypse that birthed the world. The NCR’s existence hinges on the principles of the United States—principles that, if anything, helped spark the original atomic conflict.
