Mexico was a sovereign state and the southern neighbor of the United States of America. New California Republic settlers and Rangers are active in the former Mexican state of Baja.



Mexico suffered at the hands of both natural disasters and man-made ones. In 2042, a major earthquake hit Mexico City and due to its usefulness in reclamation and disaster cleanup, the Mister Handy general construction robot became the leader in sales in Mexico.[Non-game 1] By 2051, the United States had placed various economic sanctions on Mexico, citing political instability and pollution, but the actual reason was to protect business interests and the oil supplies with in Mexico. These sanctions would severely destabilize Mexico and the United States Armed Forces would enter Mexico to ensure the operation of oil refineries, all at Mexico's expense.[Non-game 2] Yet despite this disaster and destabilization, Mexico remained a vital partner of the United States, once again due to business interests and the oil supply it provided. Businesses that operated in Mexico before the war included Petró-Chico, an oil company effectively owned by the American Poseidon Energy, and the publisher of a newspaper entitled El Periódico de las Aburridas.[2]

The Great War and aftermath

It suffered widespread devastation during the Great War, on October 23, 2077. As the Great War occurred, Mexico was bombarded by nuclear weapons. The capital city was turned into radioactive ruins, although perhaps spared from the even greater destruction seen elsewhere, such as in Washington, D.C. or Bakersfield. The collapse of society resulted in total chaos, and Mexico City was quickly taken over by looters, who formed the beginning of the raider tribes.[3] To escape the violence, citizens fled, some traveling across the now non-existent American border to locations such as Zion Canyon.[4][5]

Mexico's environment, like that of the United States, was dramatically altered in the aftermath of the Great War. Radioactive waste released from Control Station Enclave drifted down the coast of California and Mexico, causing irreversible ecological damage. The western beaches were saturated with toxic waste and sea life irradiated by indiscriminate dumping of waste into the ocean.[6] Ranger Chief Hanlon mentions both night stalkers and bighorners are present in the region.[7]

By the 23rd century, the New California Republic has expanded into the former Mexican state of Baja. A small number of settlers attempted to establish a settlement and the inhospitable, arid terrain led to a number of conflicts with the local population. In at least one instance, at Rattletail, five NCR settlers were responsible for killing over two dozen people who tried to gather water at the well they claimed as their own, the only one of which in a radius of fifty miles. The settlement was abandoned after the Ranger leader sent to protect the town from "raider" attacks persuaded them to abandon it with a fake story about a hundred-strong raider army bearing down on the place.[7]

Years later, the Republic deployed NCR Veteran Rangers into the former Mexican region, to which Chief Hanlon described as sending their "most experienced rangers to chase ghosts down in Baja," creating a more precarious situation for those fighting in the Mojave campaign.[8]


Known Mexicans


  • In Fallout: New Vegas, the Mexican flag appears wrapped around the stock of the unique hunting rifle, Paciencia.
  • A modern version of a replica neolithic shovel made in Mexico was mentioned in the Wixon's Shovel Museum.[9]


Mexico is mentioned in Fallout, Fallout 2, Fallout: New Vegas and its add-on Honest Hearts, the Fallout 4 add-on Nuka-World, the Fallout Bible and in design documents for Black Isle's canceled second iteration of Fallout 3 (codenamed Van Buren).[Non-canon 1][Non-canon 2]



  1. Paciencia
  2. The Courier: "What's "Petro-Chico?""
    Raul Tejada: "You never heard of Petro-Chico, un Amigo de Poseidon Energy? Ah, of course not. They were an oil company in Mexico, back before the War."
    (Raul Tejada's dialogue)
  3. Raul Tejada: "After the fire, I knew my sister and I couldn't stay at Hidalgo Ranch anymore. The refugees still wanted me dead - they even put a bounty on me. I remember how scared Rafaela was. I told her if she came with me, we'd see the vaqueros - she used to love the rodeo, especially the trick riders. We figured maybe we could find help in Mexico City - we were young, we didn't know what had happened, really. We didn't understand about the bombs."
    The Courier: "Wasn't Mexico City basically annihilated in the Great War?"
    Raul Tejada: "I don't think it was as hard hit as DC or Bakersfield, but it was bad enough. By the time we got there, the city was a radioactive ruin. Still, the city was full of looters, already forming into the beginnings of raider tribes. Crime was bad before the War, but now it was a nightmare. We were living like scavengers, scraping by on what little food we could find, always looking for medicine for my burns. And then, of course, the radiation started to kick in, turning me into this handsome devil you see before you."

  7. 7.0 7.1 The Courier: "There must be something good the rangers have done that you're proud of."
    Hanlon: "[SUCCEEDED] It's kind of a long one, but all right. About twenty, twenty-five years ago, a group of NCR settlers pushed way south into Baja. I guess it doesn't seem so far now if you look at a map, but back then, they were out a ways. They built this little shanty town around a well in the middle of nowhere. Called it Rattletail."
    The Courier: [Continue]
    Hanlon: "Word got back to one of our stations that raiders had been attacking the place. I went out with six rangers. We must have been on the trail for a week before we got to Rattletail. We lost one woman to Night Stalkers and another almost died of dehydration. When we reach the place, it's six shacks set up around an old well. There's over two dozen bodies lying in the dunes way outside of town and five men with .308 rifles crouched behind sand bags. And these bodies, these people out in the sand, they aren't raiders. Aren't even heavily armed. They're just people who were trying to get to the only well in fifty miles. I didn't have to talk to the men to see that they did not care one bit. They had planted an NCR flag over the well and they would not budge until every last one of them was laid out, dead and cold. So I walked up and told them there was a group of raiders coming, one hundred strong. I made up some cockamamie name for them and everything. The men looked at each other, looked at us, and asked me what we were going to do about it. I told him we would take them back into NCR territory because we had already lost ten rangers on the way out. Ten rangers, five men with .308 rifles. Well, that was enough for them. They packed up what they could and we took them back north. Last I heard, they settled somewhere in Anza-Borrego. Raised Bighorners. Had some tough times, but it worked out okay for them. So there you go. That's my one bit of good."
    (Hanlon's dialogue)
  8. The Courier: "How is NCR doing?"
    Hanlon: "It's no secret that we've had better campaigns. Holding this whole length of river isn't easy. We're stretched thin and the Long 15 just keeps getting longer. Slow to get supplies. Slower to get reinforcements. NCR's senate has got funds tied up at the Boneyard and President Kimball ordered our most experienced rangers to chase ghosts down in Baja."
    (Hanlon's dialogue)
