Prior state
At the interval's start the claim that statehood and maritime entitlements survive the loss of habitable territory has been asserted, argued, and partially endorsed in advisory law, but has never been tested by an actual case of complete uninhabitability. Adaptation works have kept the lowest atolls marginally habitable, and their populations have been leaving for two generations.
Material change
The fork closes. A class of states loses habitable territory and retains full legal personality: treaty capacity, membership in international bodies, the power to confer nationality, and — decisively — maritime zones fixed at baselines deposited before inundation. Those zones are valuable, containing fisheries governed under DEV-16, seabed minerals, cable corridors, and orbital and spectrum coordination rights. Statehood is re-founded on a registered population and a legal seat rather than on territory.
Why now
Early-century, because the physical threshold that matters is not mean sea level but freshwater-lens failure and storm-surge frequency, and those cross for the lowest atolls in the interval's first decades. The legal preparation is complete before the physical trigger, which is why the resolution is rapid once it arrives.
Mechanism and resistance
The mechanism is the deposit-and-freeze of baselines combined with the self-interest of the many coastal states that prefer fixed maritime boundaries to boundaries that migrate with their coastlines — a much larger constituency than the affected states themselves. Resistance comes from distant-water fishing powers and seabed interests that would prefer the zones to revert to high seas, from host states asked to accommodate relocated populations holding extraterritorial legal status, and from the general anxiety about precedent that attaches to any change in the definition of a state.
Consequences
The deterritorialized states become, in effect, sovereign trusts: small registered populations, substantial maritime revenues, administration conducted from host territories, and citizenship as the principal national asset. This works better than expected for the states concerned and creates a durable question about what else a state is. The precedent is then used by claimants with no connection to sea level — governments in exile, indigenous nations, and populations displaced by war press analogous arguments, and the international system spends the rest of the century policing a boundary it did not intend to draw. Host-state politics is reshaped where relocated populations concentrate, generally toward accommodation, since the populations are small and arrive with revenue.
End state
A recognized category of state without habitable territory exists in law and practice, with defined maritime entitlements and a registered citizenry. The territorial definition of statehood is formally qualified for the first time since it consolidated, and the qualification is narrow, contested, and stable.
Observable test
continued treaty-making, membership, nationality conferral, and maritime enforcement by states whose territory is uninhabited, with zone revenues collected under baselines deposited before inundation.
Disconfirming sign
affected populations are absorbed as ordinary migrants, legal personality lapses, and the maritime zones revert to neighbouring coastal states or to the high seas.
