Doctrine of Discovery
How a Papal Decree Stole a Continent
Essay 3 of 100: Unvarnished History
Inter caetera divinae majestati beneplacita opera — “Among other works pleasing to the divine majesty.”
Inter Caetera is not subtle. Its language is worth reading directly.
Pope Alexander VI granted to the Spanish Crown “all islands and mainlands found and to be found, discovered and to be discovered” west of a line drawn one hundred leagues beyond the Azores, along with “all their dominions, cities, camps, places, and villages, and all rights, jurisdictions, and appurtenances.” The grant was permanent. It was retroactive. It covered everything.
The people already living on the islands and mainlands were not mentioned. They were not in a legal category. They were part of the properties granted. The Doctrine of Discovery completely ignored their humanity, as it ignored the well-being and environmental stewardship of the vast territories so casually claimed.
The theological argument is this: God gave dominion over the earth to Saint Peter. Saint Peter’s successor is the Pope. The Pope is drawing the line. Therefore the line is God’s line. It made sense to people that believed everything on the planet was theirs by holy writ.
They believed Christian European nations have the God-given right to claim sovereignty over any land not already governed by Christians. The people living on that land have no rights that the claiming power is bound to respect. Their civilizations, their governance, their relationship to their territory — legally irrelevant. The document that authorized Columbus’s second voyage also authorized everything that followed.
One Pope. Twelve minutes. Five hundred years. Genocide. Slavery. Raping and pillaging. All blessed by an imaginary sky father.
The Three-Part Machine
The Doctrine operated as a system. Three interlocking mechanisms, each reinforcing the others.
Discovery. Christian Europeans arrive on land already inhabited by millions of people. Their arrival constitutes a legal claim. The flag goes in the ground. The claim is made. The people who have lived there for generations are now, legally speaking, occupants of someone else’s territory. They did not consent to this. They were not asked. The law did not require their consent because the law did not recognize them as legal actors capable of giving or withholding it.
Conquest. If the Indigenous people resist — and they did, consistently, intelligently, and at enormous personal cost — the violence used against them is legally justified. They are resisting a legitimate claim. The resistance is the crime, not the taking. The requerimiento, which I described in Essay 2, was the procedural expression of this principle: read the document, offer submission, and if they don’t comply, the slaughter that follows is their fault. The law said so.
Occupation. Sustained European presence cements the claim. The longer you stay, the more legal it becomes. This is why the Spanish built permanent settlements immediately. This is why the British built forts. This is why the American government spent two centuries removing Indigenous people from their land and replacing them with settlers — because occupation is the mechanism by which discovery becomes ownership.
Every land treaty the United States ever signed with Indigenous nations was negotiated under this framework. The framework already assumed Indigenous people had no full sovereignty worth respecting. The game was rigged before the first signature dried.
The American Court
In 1823, the question of divine rights came before the United States Supreme Court.
Johnson v. M’Intosh involved two competing land claims in Illinois and Indiana. One claim derived from a purchase made directly from the Piankeshaw Nation in 1773. The other derived from a grant issued by the U.S. government in 1818. The question was which claim was valid.
Chief Justice John Marshall ruled for the government grant. His reasoning is worth consideration.
Marshall acknowledged that the Doctrine of Discovery was, in his words, “pretension” based on “extravagant and absurd” claims. He acknowledged that the principle was “opposed to natural right.” He acknowledged that it produced injustice.
He upheld it anyway.
His reasoning: American property law could not function without it. If Indigenous land purchases were valid, every land title in the United States was in question. The entire structure of American property — every deed, every estate, every federal land grant — rested on the premise that the government had valid title to land it had taken from Indigenous people. That title derived from the Doctrine of Discovery. If the Doctrine fell, the titles fell. Marshall chose the titles. Marshall chose the colonizers because he was among their number.
Every land title in the United States rests on this ruling. Every land title rests on the Doctrine. The house you own, if you own one, is yours because John Marshall decided in 1823 that a papal decree from 1493 was good American law.
Think about that. Now think about it from the perspective of an ancestor of one of the people who lived here before your ancestors came and stole the land.
2005 — The Doctrine Is Still Law
If you believe all of this is ancient history, consider the following.
In 2005, the Oneida Indian Nation purchased land in upstate New York. Land that had been theirs before any European arrived. Land taken from them through treaties negotiated under the Doctrine of Discovery framework. Land they bought back, legally, on the open market, with their own money.
They attempted to re-establish tribal sovereignty over it — to remove it from local property taxation and bring it under the jurisdiction of the Nation.
The case went to the Supreme Court. City of Sherrill v. Oneida Indian Nation (2005). Justice Ruth Bader Ginsburg wrote the majority opinion.
The Court ruled against the Oneida Nation. The reasoning: the “disruptive effect” on surrounding property owners and local governments outweighed the Nation’s historical claim. Restoring Indigenous sovereignty over land legally purchased by the Nation itself was too disruptive to the existing order.
The existing order built on the Doctrine of Discovery.
RBG. 2005. The Doctrine of Discovery.
The United Nations Special Rapporteur on the Rights of Indigenous Peoples has cited this case as a continuing application of the Doctrine. It was not a relic. It was precedent. Active, living, operative precedent in the highest court in the most powerful country in the world, twelve years into the twenty-first century.
This is not ancient history. This is the law you are living under. This is the legacy of colonizers who claimed divine authority to pillage continents and destroy any civilization that stood in the way.
The Global Architecture
The Doctrine of Discovery was not American in origin. It was the operating system of European colonialism everywhere it went. America borrowed the idea, to be sure, and renamed it Manifest Destiny.
In Australia, the legal fiction was terra nullius — empty land. The British declared Australia legally empty despite the presence of between 300,000 and one million Aboriginal and Torres Strait Islander people who had lived there for sixty thousand years. Terra nullius was not overturned in Australian law until Mabo v. Queensland in 1992. Nineteen ninety-two.
In the Belgian Congo, King Leopold II claimed the territory as his personal property under the logic that it was ungoverned — that the Kongo, Luba, and Lunda kingdoms did not constitute governance recognizable by European standards. The Doctrine provided the legal cover for what followed: a regime of forced labor and systematic terror that killed between ten and fifteen million people. Leopold was incredibly cruel to the people he claimed dominion over.
In every colony, on every continent, the structure was the same: Christian European powers arrive, declare the territory legally available under the Doctrine, extract whatever value it contains, and classify any resistance as criminality rather than sovereignty.
The Doctrine was the legal architecture. The violence was the enforcement mechanism. The profit was the point.
The Line Through the Atlantic Runs Through Haiti
I grew up in Haiti.
The western third of Hispaniola — the island Columbus called La Española, the island divided by the line Pope Alexander VI drew through the Atlantic in 1493. East of a certain point: Spain’s. West: also Spain’s, eventually French, eventually Haitian after the only successful slave revolution in human history.
The weight of generational tragedies Haiti carries runs directly through this document. The Taíno were erased under the legal cover the Doctrine provided. Enslaved Africans were imported to replace them, their bodies treated as property under the same legal framework that treated Indigenous land as property — because the Doctrine established that certain people had no rights. They only existed to serve the powerful. The 1804 revolution that gave Haiti independence terrified every slaveholding empire on earth precisely because it repudiated that premise. You cannot hold people as property if they are legal persons with rights. The revolution said they were. The empires could not allow that argument to stand.
France sent a bill. 150 million gold francs — reparations to French slaveholders for the loss of their “property.” Haiti paid it, with interest, until 1947. The Doctrine of Discovery made that demand legally coherent. The people were property. The property had been taken. The property owners deserved compensation. Always, the few exploiting the many.
When people ask why Haiti is poor, the Doctrine of Discovery is a big part of the answer.
The Repudiation That Changed Nothing
In 2007, the United Nations Declaration on the Rights of Indigenous Peoples explicitly repudiated the Doctrine of Discovery. Article 28 affirms the right of Indigenous peoples to redress for lands taken without their consent. Article 26 affirms their right to own and control their traditional territories.
The United States voted against it. Signed on in 2010. Has not changed its domestic law to reflect it. In the United States, as in many places around the world, resource hoarding and different legal treatment for the rich and the powerful mean that people with nothing are still treated like they are worth nothing.
In 2023, the Vatican — five hundred and thirty years after Inter Caetera was issued — formally repudiated the doctrine document. Called it a “legal fiction.” Acknowledged it had been used to justify violence against Indigenous peoples.
Did not address what should happen to the land.
The Vatican repudiated the documen but Johnson v. M’Intosh is still the law of the stolen land.
The Through Line
The Doctrine of Discovery is the foundation of everything this series documents.
The encomienda was built on it — the system required a legal framework that classified Indigenous people as subjects rather than sovereigns. The trans-Atlantic slave trade was built on it — the same principle that said Indigenous land had no owner extended to say that certain people could be owned. Every broken treaty was built on it. The reservation system was built on it. The boarding schools that took Indigenous children from their families and forbade them from speaking their languages — built on it. The legal determination that Indigenous people could not own the land they bought back in 2005 — built on it.
And the disposition matrix — the algorithm I wrote about in Essay 77.5 that decides who can be killed without judicial review, without charge, without trial — is built on the same foundational premise: that certain people have no legal standing that the powerful are bound to respect.
Pope Alexander VI drew a line through the Atlantic in 1493.
You are still living inside that line. The algorithm is still drawing it.

Penfist is a combat veteran who served with the Army National Guard in Iraq and Afghanistan, a Marine-trained combat correspondent (MOS 4341), and the author of Dispatches from a Dying Empire at dyingempire.org. He grew up in Bangladesh and Haiti, was raised by Mennonite and Amish parents, and is a naturalized U.S. citizen.
Another excellent essay, thank you.
Funny how domestic and international law is accepted without question...except when it leads to consequences that threaten the status quo, at which point, "laws" are ignored with impunity.
The US invades Iraq and murders untold numbers of civilians under a fiction so absurd that it's embarrassing to type the acronym (WMD), ignoring international laws as war crime after war crime was committed.
Israel commits a genocide in broad daylight, and politicians and media on both sides of the political spectrum run cover for the countries committing war crimes.
Trump abducts Venezuelan leaders and the world shrugs.
SCOTUS ignores laws and precedent to blatantly reach their desired goals.
The majority of us comply with laws because that's what a civil society requires, but we do this against a background where the wealthy and powerful ignore all laws, and countries increasingly ignore inconvenient international laws.
It's important to understand how we reached our current state of impending implosion. I just fail to see how we fix what so many have broken through hubris, complacency, ignorance, fanaticism, and greed.
