Terra nullius
international law term meaning territory which has never been the subject of a sovereign nation
Terra nullius (, plural terrae nullius) is a Latin expression meaning "nobody's land". Since the nineteenth century, it has been used in international law to refer to the principle by which territories deemed not to belong to any recognised sovereign state could be acquired through occupation. In historical scholarship, the term is also used retrospectively to describe colonial practices in which European powers claimed sovereignty over lands by referring to them as empty, vacant, or unowned, including in territories where indigenous populations were present. Since the twentieth century, the application of terra nullius to inhabited territories was rejected in several jurisdictions as part of increasing recognition of Indigenous rights, including in Mabo v Queensland (No 2) in Australia. Today Antarctica remains as the only major landmass that is sometimes considered to be wholly or partially terra nullius. Other territories sometimes claimed to be terra nullius include Bir Tawil, a strip of land between Egypt and Sudan, and four pockets of land on the banks of the Danube, on the Croatia-Serbia border; both due to border disputes where both competing claims involve assigning a particular piece of territory to the other party.
Doctrine
In international law, the classical doctrine of terra nullius holds that territory can be acquired through occupation if it is not under the sovereignty of any state. Robert Jennings and Arthur Watts describe occupation as applicable to territory not already subject to state sovereignty, including uninhabited territory and territory inhabited by populations not regarded as constituting a state. Alexander Orakhelashvili states that in the 21st century there are few areas that are possibly terra nullius as almost all territory is under the sovereignty of a state.
Irene Watson argues that international law, including the doctrine of terra nullius, was part of a colonial project that divided the world into civilised and non-civilised states under which indigenous and other non-European societies were often not recognised as holding sovereignty, despite having their own systems of law and territorial organisation.

Why this record matters
The phrase “international law term meaning territory which has never been the subject of a sovereign nation” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q312461. None of the 0 selected statements returned an explicit reference.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
