Alex has a time machine. Alex wants to be revered as a god, change human history and make everyone worship him as the reincarnation of said god.

I decide to be a god of war and conquer a big part of ancient Europe, I'm alone in this quest, so I can't bring people from the present. I need to build an army in the past, and I can bring with me any kind of weapon, materials, vehicles or supplies back in time.

Where should I start building an army and how do I overcome the language barrier?

I need a Flying war machine or land vehicle that looks like a mythological beast and wield a powerful weapon that only I can use. Anyone who tries to use said items die or get injured.

After I finish my holy wars I need to make sure my followers will worship me in the altered future. How can I achieve my goals?

    $\begingroup$ Medieval Europe is very Christian. If you turn up wielding powers and weapons claiming to be a god then you're more likely to be declared a witch or demon and hunted by everyone with the ability to do so. $\endgroup$

  • $\begingroup$ @Separatrix: There were many pagan peoples medieval Europe. For example, some English Saxons remained pagan up to the second half of the 7th century, the Poles remained pagan up to the end of the 10th century, Scandiavians remained pagan up to the 12th century, and Lithuanians remained pagan up to the end of the 14th century, close to the end of the Middle Ages. In fact, the history of the early Middle Ages is in a large part the history of the Christianization of the Franks, Alamanni, Visi- and Ostrogoths and other Germanic peoples. $\endgroup$

    $\begingroup$ How is this about building a fictional world? This seems like a question asking "What would my character do in this situation?" Such questions are off topic. $\endgroup$

Author Bob Mayer in his Area 51 books had high-tech aliens masquerading as gods in ancient Human times, most notably in ancient Egypt and ancient China. They used the mythology of the day to their advantage. Forgive me for forgetting the name, but the aliens in China borrowed an early Chinese legend of a flying dragon, which they equipped with hover technology and energy weapons, which then flew around the country terrorizing the people.

In your own case, people cannot be assumed to be blind. If you're using machinery that can be seen (e.g., hand-held weapons, vehicles, or anything else that people could covet) that cannot be bound to existing mythologies then they will quickly begin to associate the "magic" with your posessions, not with you. If you can take advantage of existing mythologies, then this can be avoided... for a while.

The best technologies would be those that cannot be seen. This might be complicated, but let's use some satellites.

  • Omniscient: You know what's going on near and far. You know about advancing armies. You can reliably prophesy about your friends and enemies and even upcoming weather changes. (Many Biblical Old Testament prophecies could be explained this way.)

  • Omnipresent: The very same technology will allow you (or your "prophets") to "show up" at opportune (or, in the case of your enemies, inopportune) times. It would give you the ability to be anywhere and everywhere. Combine this wil (very) well camoflaged drones with loudspeakers and you would be very motivational.

  • Omnipotent: Add to that an satellite-based energy weapon outside of the visible spectrum, like an ultraviolet laser. (The Biblical story of Ananias and Sapphira in Acts 5 could be explained this way.)

Of course, you need to surround yourself with sycophants who are willing to take the proverbial bullet for you so that the occasional individual who has a "sense" about something being wrong can't sneak up behind you and slip a stiletto between your ribs. Carefully dispensed hallucinogenics combined with subliminal audio will help with that... because nothing can bind the faithful to you like a powerful vision.

The satellite launches can be masked as the faithful "ascending into heaven" (a good way of removing those sycophants who are getting just a little too comfortable with their power and authority). The launch site needs to be where no one can actually get to it to investigate (realistically, you can have only one Tunguska blast site). While a submarine would be convenient, an underground and underwater base might be simpler. And a nice retreat when you need a break from everybody's prayers.

You need a really good supply of antibiotics. Nothing endears the masses like a good healing, whether it be an individual or a crop. Just as valuable is a supply of herbicide, because nothing instills fear like destroying crops. Drones are once again your friend. Quiet, camoflaged drones. If you can sneak one in that's large enough, you could put out small fires or drop a stream of napalm for a quality column of fire (the story of Elijah and the Priests of Baal comes to mind).


  • Satellites, both observational and weaponized
  • Audio (loudspeakers and subliminal sound)
  • Drones (quiet and camoflaged)
  • Ultraviolet lasers
  • Hallucinogenics
  • Rocketry
  • Antibiotics
  • Napalm

And all the supporting technology needed to keep this ball of wax from melting including construction & manufacturing. That might be a bit of trouble keeping hiden, but what are dungeons really for, anyway?


There's a vast distance between the "common" monotheistic god, which usually is omniscient and omnipotent, and the old polytheistic gods, which were for sure far superior than human but they had a lot of limitations and only some specific powers.

With the current technology, one single person can't perform such a full scale "miracle" as the plagues of Egypt, therefore can't be perceived as an almighty god. On the other hand, one single person can for sure impersonate a polytheistic-level god and can definitely be seen as a demi-god without a lot of effort. I assume this person is (technically) a very skilled person, but alone he can't manage a nuclear power plant, use nuclear submarines, manage satellites, etc...

You stated that he can have any kind of material, weapon, etc... There are limitations in quantities? You'll need without any doubt A LOT of energy but if you can carry whatever you want it's not a big deal: thousand tons of fuel, solar panels arrays, etc.. Granted that you have energy, you only have to decide how to astonish the other people. The possibilities are endless!

  • You can easily cure a lot of illness, or you can easily kill hundreds people with toxic gas (and you can wear a gas mask, then you'll survive when everyone else is painfully dying, therefore you are a god without any doubt).

  • You can charm or at least influence other people with drugs.

  • You can surprise people by setting "a bush on fire, without actually burn it up" using trivial led lights, this thing could be a total miracle for someone.

  • You can't walk on water but it will be easy to remain underwater for an unreasonable amount of time for a human being (small disposable oxygen tanks).

  • You can create fire "out of nowhere", also simulating psychic powers by using a small remote.

  • If you want to scare the people in a besieged castle you can just use a bunch of fireworks or, if you want to clarify your power once for all, you can use a couple of javelin missiles (actually i have to check if they need some kind of GPS assistance, in any case the old bazooka can also demolish a medieval castle).

  • Hercules god-like force? Military exoskeleton.

  • Lightning strike power like Zeus? Hidden weapon in your forearm, you point your hand, a thunder like sound and a small fire from your god powers occur, and the person you're facing is dead.

  • Do you want the power of curse someone? Infrared lased mounted on your crown, even a low power module: if someone dares to look at your face he will be blinded forever and no one will have a clue about the real cause (safety glasses for this wavelength are transparent in our visible spectrum, then they can be easily added to your helmet and no one will suspect that a transparent glass is actually helping you).

  • You want to create taboo zones in which no one should go? Claymore mines painted with your symbol? After some casualties everyone will learn that your symbol deserves respect.

  • Given that you are a trained pilot, which is not common but still reasonable, you can have your own dragon. I suggest the Kamov Ka-50, a single pilot attack helicopter, with a nice shape and an ejector seat (just in case.. I doubt that anything could harm this vehicle). With such a "beast" at your command you can rule every battlefield, and i really doubt that anyone else could have any chance to use this against you.

I stop here but the list could continue for days. The main point is that EVERYTHING that's common for us will be astonishing for a medieval person, is not only a matter of "mechanical" power, even a stupid Polaroid can be seen as a miracle, especially for the person that will receive a portrait in almost not time.

With a gopro and a projector you can show to a crowd what happened to another army in a previous battle, and even if the enemy army has been obliterated in minutes, the most important concept is that you can evoke and show previous events. They will freak out only for this! Think about "L'Arrivée d'un train en gare de La Ciotat", which was the first projected film. In that occasion Der Spiegel wrote that the film "had a particularly lasting impact; yes, it caused fear, terror, even panic." I know that this description might be exaggerated, but remind that it was the state of the art of the current technology, not something that no one even theorized about. You don't need the Death Star's death day to scare someone that never saw a firework.

A stupid hidden walkie talkie can let you hear secret meetings, therefore it seems that you can read minds, or you can spread your voice/orders in your temples or to your generals.

This reminds me of the army question. It will be quite easy to build an army that can defeat every enemy and also that can't hurt you, the technology gap is so wide that they can have really unfair advantage against the enemy, but the "true" power is only on/in you.

  • Even using the usual medieval items, your army can have better armors, better weapons, better siege tools, better tactics. You only have to share some knowledge with your blacksmiths and generals.
  • Drugs and medicines: you will have an army of lucid berserkers, that can also be healed faster/better respect to the standard.
  • If you don't want to risk your safety giving powerful poison to other people, you can still provide them "holy grenades" filled with tear gas. I doubt that a infantry charge could be properly finalized if your army has access to tear gas grenades, or at least the charge will be seriously crippled.
  • With good radio equipment, in case of an exceptionally strong enemy, the god (you) can be prayed (called via radio) and with your flying beast (said helicopter) you can quickly reach the critical point, destroy the main enemy force, and then let your army to clean up the remaining forces.

With your god-like powers I presume you don't really need to build an army, everyone will try to be part of your army and I doubt that any opposing army can keep enough morale after a few tricks (if you are gracious) or after few missiles or gas bombs (if not).

Actually, I'll change my original statement: you definitely can be worshiped as an almighty god. You can win any war and kill every person. Basically no one can object your divine nature. They won't object because they truly think this, or you can simply remove any opponent and the history is as usual written by the winner.

To reply at L.Dutch:

IMHO you don't have to worry about that: good and bad, right or wrong are a moral concept. If you define the moral you can decide what's right and what's wrong. Remember: you are the winner of every battlefield, then you can just "write the history" as you wish. Why not? Moreover, some previously suggested actions could seem evil for us (us who?) and NOW but, for example, a thousand years ago actions like "torture already defeated enemies" or "burn people that use medical erbs" were ok, no big deal. Actually, thinking about the catholic inquisition, precisely the god's emissaries performed some of the cruelest actions and no one bat an eye. They had only money, army and propaganda and now look at the fortune they made along the centuries. You would have true god-like powers, you would be way more powerful than them.

And more: even if we remove your possiblity to "redefine moral rules applying your power", the suggested actions aren't so strange for a god, so you don't actually have to redefine a lot. The polytheistic-level gods usually behaves as an immature, selfish and cruel person with some superpowers. The first examples that come to my mind: - Prometheus, chained to a rock and doomed to be perennially devoured, because he wanted to help humans. - Hercules, he massacred his family because his stepmother was pissed and drove him frenzy. - The Gorgon Medusa, a former beautiful woman, mutated by Athena in a "monster with a horrifying visage that turned those who beheld her to stone". And why? Because she slept with (or has been raped by) Poseidon. As you can see, at least in Greece, no one really cared about our current morality to worship some beings as gods. And even now, with our morality, if these people actually did exist, it wouldn't be so strange to worship them as the gods they are.

It's a non sense to discuss this in the case you are trying to be the monotheistic-level, almighty, omnipotent unic god. I mean, here in Italy we are mostly Catholic and our god turned the water into blood, killed all the Egyptians first-borns, and once flooded the whole world, killing EVERYTHING except a bunch of people and few animals. It's difficult for me to imagine something something more devastating and, since the flood didn't turn god into evil (which is, as previously said, only a relative concept), i don't know what action can do that.

Depends in what period of Medieval Europe. From what I remember, Medieval Europe is largely considered the 1000 years from 400+ to 1400+. At the end of it, Europe was Christian and i doubt you could be considered a god. But at the start it might work, especially as Christianity was not present everywhere. If you would start from the Nordic countries, it would be best if you would present yourself as Thor I guess. Nordic people are good because they believed in multiple gods, they had a strong war philosophy so they could be your selected people to conquer Europe.

Currently there is no weapon I could suggest, but as teleportation is not invented yet, i think the starting point is also somewhere in the future, so we can imagine that some sort of high energy taser (high enough to kill instantly, maybe with a bit of distance between the user and the target) could exist and it could be made in the form of a hammer (to resemble the mythological description). Digital fingerprint identification would guarantee the use only by the owner. Also some sort of powerful flying drone would be your vehicle, but obviously you would have to bring power sources. If it would be electrical, you could have something like solar generators, or if it is even further in the future a small nuclear reactor. If both the hand weapon and the flying vehicle use only energy, this generators would suffice for everything (with current weapons the problem is that you need bullets and an entire industrial society and as you have to teach the people stuff so they can help with running this industry you would lose part of the "magic" effect).

This flying vehicle could also carry a weapon like a laser, or a different targeted condensed high energy weapon. As a lot of structures at the start of medieval Europe had a lot of wood, lighting them on fire from a distance would be seen as a godlike power.
