Who Is Supposed to Live Inside the Earth?

On 10 April 1818, former U.S. Army officer John Cleves Symmes Jr. circulated one of the more ambitious geographical announcements of the nineteenth century.

He proposed that Earth was hollow, composed of several concentric spheres and open at both poles through enormous entrances. He went further than merely proposing a model. Symmes declared the interior habitable and offered to lead an expedition there if sufficient support could be obtained. His theory became the subject of public lectures, newspaper discussion and petitions seeking government backing for polar exploration.

Symmes was not describing a tiny cave system beneath Ohio. His Earth contained an immense inner surface with land and seas of its own, accessible through polar openings large enough for an expedition to enter.

The idea belonged to an age in which enormous portions of the polar regions remained geographically uncertain. Antarctica had not yet been mapped, the Arctic remained dangerous and incomplete on European charts, and direct observation of the poles lay decades in the future.

A hole at the top of the world still had somewhere to hide.

The Hollow Earth Quickly Acquired Inhabitants

Symmes wanted exploration, but literature was quicker.

The anonymously published 1820 novel Symzonia described a voyage into the interior through the southern polar opening and presented an advanced civilisation living there. Scholars have long connected the book with the contemporary excitement surrounding Symmes’s theory.

The pattern was established remarkably early.

First came a proposed physical structure: a hollow planet with polar openings.

Then came the obvious question: if there is an interior world, who lives there?

During the nineteenth century the answer increasingly became something more interesting than lost sailors or ordinary human settlements. The interior could preserve races older than surface civilisation, societies spared from catastrophes, alternative political systems or cultures possessing knowledge unavailable above ground.

The Hollow Earth was becoming less like an empty geological cavity and more like a second world hidden inside the first.

Then Bulwer-Lytton Put the Vril-ya Underground

In 1871, Edward Bulwer-Lytton published The Coming Race.

Its narrator descends through a mine and discovers a vast subterranean civilisation inhabited by a people called the Ana, among whom the technologically and intellectually advanced Vril-ya possess mastery over a force known as Vril. Bulwer-Lytton describes their ancestors as surface dwellers driven underground by ancient geological catastrophe, after which they developed cities, artificial illumination and a civilisation that eventually mastered the strange universal force.

Vril can illuminate, heal, influence living organisms, affect minds and destroy with extraordinary power. Bulwer-Lytton presents it using the language of electricity, magnetism, mesmerism and nineteenth-century speculation about forces that might someday be unified.

The novel also gives the subterranean civilisation a deep history. Its inhabitants describe ruins belonging to even older races within the Earth and preserve traditions of a world above that many of them regard almost as mythology.

This adds something important to the developing underground mythology.

The inhabitants are not primitive survivors.

They are ahead of us.

The hidden world beneath humanity has become a repository of superior knowledge.

Vril Escaped From the Novel

As we have already seen, Vril did not remain confined to Bulwer-Lytton’s fiction.

Occult readers adopted the term, and later esoteric traditions treated Vril as something closer to a hidden natural or spiritual force. By the twentieth century it had become entangled with theories involving secret societies, lost civilisations and eventually advanced German flying machines.

That transformation matters to the Hollow Earth story because Bulwer-Lytton provided several ingredients at once: an advanced subterranean people, an ancient catastrophe separating them from surface humanity, hidden technology and a power unknown to conventional civilisation.

Those ingredients would recur under different names.

Another underground kingdom was about to appear in France.

This time it was not presented as a novel.

Saint-Yves Described Agarttha

During the 1880s, French occultist and political thinker Alexandre Saint-Yves d’Alveydre developed the idea of a secret initiatory centre called Agarttha.

His Mission de l’Inde en Europe was written during this period but became widely available only after his death, when it was published in 1910. Saint-Yves said that he had received teachings concerning Agarttha from an Eastern instructor named Hardjij Scharipf and described its organisation, sacred knowledge and political-spiritual hierarchy.

Agarttha was not simply another underground city.

Saint-Yves conceived it as an enormous hidden centre preserving knowledge from previous ages and governed according to his ideal of synarchy, a hierarchical political and spiritual order. His description places its domain both beneath the surface and across a much wider hidden network, with subterranean repositories preserving traditions unavailable to ordinary civilisation.

The inhabitants were therefore not merely hiding.

They were guarding something.

With Agarttha, the underground kingdom became an archive, initiatory centre and invisible government at the same time.

What had begun with Symmes as geography was becoming metaphysics and politics.

Theosophy Added Hidden Masters and Lost Human Histories

The nineteenth-century occult revival contributed another set of ideas that would later overlap with Hollow Earth mythology.

Theosophical writers described hidden adepts or Mahatmas, secret centres of spiritual instruction and immense cycles of human and planetary evolution. Later Theosophical traditions also developed Shambhala as an earthly centre associated with a hierarchy of spiritual teachers, although Theosophical sources themselves show that later teachings about Shambhala should not automatically be attributed directly to Helena Blavatsky.

This distinction matters because modern Hollow Earth narratives tend to merge everything into one underground administration.

Hidden masters become inhabitants of Agartha.

Agartha becomes Shambhala.

Shambhala becomes a subterranean city.

Vril becomes its energy.

Polar openings become its entrances.

But those elements entered Western esoteric culture through different sources and did not originally describe one uniform place.

The merger came later.

Shambhala Was Already Something Else

Shambhala has a much older religious identity than modern Hollow Earth literature.

In Tibetan Buddhist Kalachakra traditions, Shambhala is a hidden sacred kingdom associated with enlightened rulers who preserve the Kalachakra teachings. Tibetan artistic traditions represent it as a land surrounded by mountains and organised symbolically like an eight-petalled lotus, with a central capital and palace.

The Kalachakra tradition also contains a future prophetic cycle in which rulers of Shambhala emerge during a period of conflict, followed by the establishment of a new age favourable to spiritual practice. The tradition operates simultaneously on geographical, historical and spiritual levels, and modern Buddhist explanations emphasise that Shambhala should not be reduced to an ordinary hidden city waiting to appear on satellite photography.

Most importantly for our story, the Buddhist tradition does not require Shambhala to be inside a hollow Earth.

That association belongs to another stage of transmission.

So how did a hidden Buddhist kingdom surrounded by mountains become neighbours with an underground empire called Agarttha?

Ferdinand Ossendowski Heard About Agharti in Mongolia

In 1922, Polish writer and traveller Ferdinand Ossendowski published Beasts, Men and Gods, an account of his extraordinary journey through Siberia and Mongolia during the chaos following the Russian Revolution.

Near the end of the book he records stories told to him in Mongolia about a subterranean kingdom he calls Agharti and its mysterious ruler, the King of the World.

The parallels with Saint-Yves’s earlier Agarttha attracted considerable attention. René Guénon subsequently examined both traditions in his 1927 Le Roi du Monde, explicitly discussing Saint-Yves and Ossendowski while interpreting Agarttha as a supreme spiritual centre rather than merely a hidden geographical state.

By the 1920s, therefore, the West had several overlapping underground or hidden-world traditions in circulation.

Symmes had given the planet polar doors.

Bulwer-Lytton had populated the depths with an advanced race.

Saint-Yves had placed a secret spiritual-political civilisation underground.

Ossendowski had brought stories of Agharti and the King of the World out of Mongolia.

Theosophy had popularised hidden masters and concealed centres of wisdom.

Tibetan Buddhism already possessed Shambhala.

At some point, the map became irresistible.

Agartha and Shambhala Began Moving Toward Each Other

Modern literature frequently uses Agartha and Shambhala almost interchangeably.

The historical traditions are more complicated.

Shambhala belongs to Indian and Tibetan religious literature and has a specific place in the Kalachakra tradition. Agarttha enters Western occult literature prominently through Saint-Yves. Later esoteric writers increasingly placed the two ideas beside one another and interpreted them as different names or aspects of a concealed spiritual centre.

Once that identification occurs, other elements can attach themselves very easily.

If the hidden kingdom is inaccessible, perhaps its entrances are secret.

If it is underground, perhaps the entrances lie in remote mountains.

If the Earth itself has polar openings, perhaps those are larger entrances.

If its inhabitants preserve ancient knowledge, perhaps they possess advanced technology.

And if strange craft are appearing in the sky, perhaps they are not arriving from space at all.

Perhaps they are coming up.

UFOs Changed the Direction of Travel

The twentieth-century UFO era added a new population to the underground.

Flying-saucer literature increasingly included stories of subterranean bases, hidden technologically advanced races and craft emerging from inaccessible parts of the Earth. Older Hollow Earth geography could now be combined with modern machines.

The poles became especially useful because they had already belonged to Symmes’s model.

Antarctica then supplied another layer through the 1938–39 German expedition, Operation Highjump and later stories of hidden German installations beneath the ice. By the 1970s and afterward, Hollow Earth narratives, Nazi-survival mythology and UFO traditions increasingly occupied the same polar landscape.

This does not mean Symmes was predicting Haunebu flying discs in 1818.

It means that his holes were still available when somebody eventually needed somewhere for them to fly through.

So Who Was Supposed to Be Down There?

Over two centuries, the answer keeps changing.

For Symmes, the interior was habitable territory waiting to be explored.

For nineteenth-century fiction, it became a place where alternative societies could develop beyond surface civilisation.

For Bulwer-Lytton, it contained an ancient technologically superior race controlling Vril.

For Saint-Yves, the depths concealed Agarttha, an initiatory civilisation preserving knowledge and governing itself according to a hidden order.

Later esoteric traditions filled hidden centres with adepts and masters.

Buddhist Shambhala contributed the much older image of an inaccessible sacred kingdom ruled by custodians of spiritual teaching, although its original religious geography is not simply the Hollow Earth map later writers created around it.

Ossendowski brought the King of the World and Agharti into another strand of the story.

Then UFO culture gave the underground civilisation aircraft.

The strange question is therefore not simply whether anyone lives inside the Earth.

It is why the same interior repeatedly became the place where human beings stored whatever they believed the surface world had lost: ancient races, forbidden history, spiritual authority, superior technology, immortal masters, alternative governments and knowledge that somehow survived catastrophe.

Perhaps that is why Hollow Earth mythology never stays empty for very long.

Once humanity imagines another world beneath this one, somebody inevitably moves in.
