In 1899, the British drew a border between Egypt and Sudan along the 22nd parallel — a straight line, the kind empires like, cutting across desert without regard for who lived where. In 1902, the British drew a second border — an administrative line, adjusted to reflect the grazing territories of local tribes — that deviated from the 22nd parallel in two places. One deviation created the Hala’ib Triangle: 20,580 square kilometers of Red Sea coastline with a port, fishing grounds, manganese deposits, and a population of 10,000-30,000 people. The other deviation created Bir Tawil: 2,060 square kilometers of featureless Saharan desert with no permanent population, no infrastructure, no resources of consequence, and summer temperatures exceeding 50°C. The 1899 line places Hala’ib in Egypt and Bir Tawil in Sudan. The 1902 line places Hala’ib in Sudan and Bir Tawil in Egypt. Each country claims the line that gives it Hala’ib. Each country’s claim places Bir Tawil in the other country’s territory. Neither country claims Bir Tawil, because claiming it would mean accepting the border that surrenders the Hala’ib Triangle. The result is that Bir Tawil — roughly the size of Luxembourg — is the last significant non-Antarctic terra nullius on Earth: land that belongs to nobody, not because nobody wants land, but because the cost of claiming this particular land is losing a much better piece of land 250 kilometers to the east.
The Hala’ib Triangle, meanwhile, has been controlled by Egypt since 1995. Egyptian police, Egyptian administrators, Egyptian-built roads and schools and clinics. Sudan protests. Egypt ignores the protest. The de facto resolution is that Egypt has both pieces — it controls Hala’ib by force and Bir Tawil by default, because nobody else is there — while the de jure resolution is that the border remains undefined, the disputed territory remains disputed, and Bir Tawil remains the cartographic residue of two empires, two borders, and two countries that would rather leave a Luxembourg-sized hole in the map than concede the coastline.
The mechanism
The Bir Tawil paradox is the cleanest illustration of a principle the Off The Map course has been documenting across multiple case studies: borders are not descriptions of geography — they are assertions of interest, and when two assertions conflict, the territory that falls outside both assertions ceases to exist in the international system.
The Croatia-Serbia Danube dispute created terra nullius by accident — the river moved, the map didn’t, and neither country’s interpretation of the border covered the pockets in between. Bir Tawil is terra nullius by design — not in the sense that anyone planned to create unclaimed territory, but in the sense that both countries have made a deliberate strategic calculation to not claim it, because the claim that includes Bir Tawil excludes Hala’ib. The Croatian-Serbian terra nullius is a cartographic error. The Egyptian-Sudanese terra nullius is a cartographic strategy.
The Ilemi Triangle is the structural cousin: five colonial lines drawn through East African territory, three claimant countries, zero agreed boundary. But the Ilemi Triangle is claimed — Kenya administers it, South Sudan disputes it, Ethiopia has treaty-based positions. Bir Tawil is unclaimed. The difference matters legally: a disputed territory has competing sovereigns who can, in theory, negotiate. Terra nullius has no sovereign. There is no one to negotiate with, because there is no one to negotiate for.
The people who are actually there
Bir Tawil has no permanent population in the sense that census-takers mean — no fixed settlements, no addresses, no utility connections. It does have people. The Ababda and Bishari tribes — nomadic pastoralist communities whose grazing territories predate both the 1899 and 1902 borders — cross through Bir Tawil seasonally, as they have for centuries, following water sources and pasture with no regard for whether the territory they’re traversing belongs to Egypt, Sudan, or nobody. The Ababda in particular consider the territory theirs in a way that has nothing to do with the sovereignty framework that created the dispute.
In recent years, artisanal gold mining has drawn small numbers of prospectors into Bir Tawil and the surrounding border region. The mining is unregulated — there is no regulatory authority because there is no sovereign — and the environmental consequences are what you’d expect from mercury amalgamation processing in a desert with no oversight: mercury pollution in soil and groundwater, in an area where the nomadic population depends on wells for drinking water. The rare earth and conflict minerals courses document supply chains where extraction in ungoverned territory produces environmental and human costs that nobody is responsible for cleaning up. Bir Tawil’s artisanal gold mining is the smallest-scale version: extraction without governance, profit without accountability, contamination without jurisdiction.
The North Sentinel Island post documented a population that has never consented to the sovereignty of the state that claims it. The Ababda and Bishari of Bir Tawil inhabit territory that no state claims at all — they are, in the eyes of the international legal system, people living nowhere, crossing borders that don’t exist, grazing livestock on territory that belongs to nobody, and drinking water contaminated by mining that no regulatory authority oversees because no regulatory authority has jurisdiction.
The kingdom of a six-year-old
Bir Tawil’s terra nullius status has produced, predictably, a parade of self-declared monarchs. The most widely covered was Jeremiah Heaton, a Virginia farmer who traveled to Bir Tawil in June 2014, planted a flag, and declared the “Kingdom of North Sudan” — not for geopolitical reasons but because his seven-year-old daughter Emily had asked him if she could be a real princess. Disney optioned the story for a film. The Washington Post ran it as a human-interest piece. The internet briefly debated whether a Virginia farmer could, in fact, become a king by planting a flag in unclaimed desert.
He could not. Heaton’s “kingdom” was never recognized by any country, any international organization, or the Ababda tribe whose grazing territory he’d planted the flag on. But the story illustrates the conceptual gap that terra nullius creates: in a world where virtually every square meter of habitable land is claimed by at least one state, unclaimed territory becomes an invitation — to dreamers, libertarians, micronationalists, and fathers with daughters who want to be princesses. The micronations post documented entities that declare statehood without capacity. Bir Tawil’s claimants go a step further: they declare statehood on territory that no state has claimed, in the apparent belief that the absence of a competing claim constitutes an opportunity rather than a warning.
In January 2025, the “Principality of Bir Tawil” — a separate project from Heaton’s kingdom — applied for observer status at the United Nations. The application has not been acted on. Multiple additional claimants maintain websites, issue “passports,” and sell “citizenship” or “noble titles” to online buyers. None have established permanent presence on the territory, because the territory is 2,060 square kilometers of Saharan desert with no water infrastructure, no road, no electricity, no building of any kind, and summer temperatures that will kill you if you don’t have your own supply chain. Declaring sovereignty is easy. Surviving sovereignty is the part that requires a state.
Hala’ib: the prize that explains the void
The reason Bir Tawil exists as terra nullius is Hala’ib. Understanding Bir Tawil without understanding Hala’ib is like understanding the Fergana Valley’s enclaves without understanding the water conflict that makes them lethal — the void only makes sense in the context of the thing both parties are actually fighting over.
Hala’ib is ten times the size of Bir Tawil, with Red Sea coastline, a deepwater port at Halayeb town, fishing rights, manganese deposits, and potential offshore oil and gas resources. Egypt has administered the triangle since 1995, following a Sudanese-backed assassination attempt against Egyptian President Hosni Mubarak in Addis Ababa that year. Egypt deployed military forces, established administrative control, and has since built infrastructure — roads, schools, clinics — that treats Hala’ib as Egyptian territory. Sudan has protested to the UN on multiple occasions. The protests have produced no action. Egypt’s control is de facto and unchallenged on the ground. The situation mirrors Western Sahara — an occupying power that has physically controlled the territory long enough that the occupation has become the status quo, while the legal claimant protests without effect.
Sudan’s current civil war — which erupted in April 2023 between the Sudanese Armed Forces and the Rapid Support Forces, displacing over 10 million people and producing what the UN has called the world’s worst humanitarian crisis — has effectively eliminated any Sudanese capacity to press the Hala’ib claim. A government that cannot control Khartoum is not in a position to contest Egyptian administration of a Red Sea triangle. The Azawad and Myanmar posts documented states disintegrating into competing armed factions. Sudan in 2026 is the same process at an even larger scale — and every moment of Sudan’s disintegration is a moment in which Egypt’s control of Hala’ib becomes more permanent, and Bir Tawil’s terra nullius status becomes more irreversible.
Why they’re in the course
Bir Tawil and Hala’ib are the Off The Map case study in the geometry of competing claims — where two borders, two countries, and one coastline produce a territory that everybody wants and a territory that nobody wants, and the territory that nobody wants exists only because claiming it would mean losing the territory that everybody wants. Transnistria exists because a patron sustains it. Artsakh ceased to exist because a patron failed to protect it. Diego Garcia’s population was removed because the territory was too valuable. Bir Tawil’s population is ignored because the territory is too worthless — and the worthlessness is precisely what makes it terra nullius, because neither country will accept the cost of claiming it.
The Ilemi Triangle has five lines and three claimants. The Croatia-Serbia Danube has two interpretations and zero claimants for the pockets in between. Bir Tawil has two lines and zero claimants for the desert in between — and a parade of self-declared kings who mistake the absence of a claim for the presence of an opportunity. The map has a hole in it. The hole is the shape of a country that nobody’s border can afford to include. And inside the hole, the Ababda keep grazing, the miners keep mining, and the kings keep planting flags — in a territory that is, legally, nowhere, and will remain nowhere as long as Hala’ib is worth more than the hole.
This is the kind of place our Off The Map course was built to map — where two borders drawn by the same empire in three years created a piece of Saharan desert the size of Luxembourg that neither Egypt nor Sudan will claim because claiming it means losing the Red Sea coastline both of them want, a Virginia farmer once declared himself king of it so his daughter could be a princess, a “principality” applied for UN observer status in 2025, nomadic herders cross it without knowing or caring whose territory it isn’t, artisanal gold miners contaminate its groundwater with mercury under the jurisdiction of no one, and the entire paradox exists because the British couldn’t decide where to put the line — so they put it in two places, and the gap between them has been nobody’s problem, and nobody’s country, for 127 years.
