**Historic waters** in the [law of the sea](/source/Law_of_the_sea) is a concept designating the waters that are treated by a [coastal state](/source/Coastal_state) as a part of its [internal waters](/source/Internal_waters), contrary to the established [international law](/source/International_law), but with acquiescence of other states. **Historic bay** is a narrower term for a [bay](/source/Bay) with such a "historic title".[1] The concept of historic waters appeared at the end of the 19th century and some commentators consider it to be [anachronistic](/source/Anachronistic) in the 21st century.[2] **Ancient title** is a similar [judicial doctrine](/source/Judicial_doctrine) based on a different reasoning: during the [Age of Discovery](/source/Age_of_Discovery) and prior to the 18th-century concept of [freedom of the high seas](/source/Freedom_of_the_high_seas), the open sea was considered [territoria nullius](/source/Territoria_nullius) (nobody's territory) and thus claims for newly discovered parts of it by [colonial powers](/source/Colonial_powers) were legitimate.[3] Some historic bay claims were subsequently converted to [juridical bays](/source/Juridical_bay) (for example, [Delaware Bay](/source/Delaware_Bay) and [Chesapeake Bay](/source/Chesapeake_Bay) in the US). The goal of protecting "vital" waters is pursued by the states through the modern [maritime zones](/source/Maritime_zone).[2]

## Historic rights in the case law

The concept of historic water goes against the established modern principles of claiming the internal waters, as originally defined by the [Convention on the Territorial Sea and the Contiguous Zone](/source/Convention_on_the_Territorial_Sea_and_the_Contiguous_Zone) in 1958: [normal baselines](/source/Normal_baselines), [straight baselines](/source/Straight_baselines), [baselines of bays](/source/Baselines_of_bays).[4]

The Convention also mentioned (but did not define)[5] the historic bays following the Second Committee of the [League of Nations Codification Conference, 1930](/source/League_of_Nations_Codification_Conference,_1930) that accepted the existence of historic waters while underscoring the lack of their definition. Since then the international bodies avoided defining the term and even used the term *established rights* instead.[6] The intent of adding the term to Convention was to create an exception accommodating the bays that are already recognized as part of the internal waters of sovereign states.[7]

In its 2016 ruling in [Philippines v. China](/source/Philippines_v._China), an [arbitral tribunal](/source/Arbitral_tribunal) operating under [United Nations Convention on the Law of the Sea](/source/United_Nations_Convention_on_the_Law_of_the_Sea) confirmed the existence of historic rights, although stopped short of endorsing the [sovereignty](/source/Sovereignty) aspect of historic claims by stating that the "[h]istoric rights may include sovereignty, but may equally include more limited rights, such as fishing rights or rights of access".[8] The tribunal attempted to separate *historic rights* in their limited sense, while applying the term *historic title* when discussing the sovereignty.[6]

## Proof of title

The [International Law Commission](/source/International_Law_Commission), in its "Juridical régime of historic waters, including historic bays", required that for the claim to be valid under the doctrine of historic title, the state needs proofs of:[9]

- a three-pronged *exercise of authority*: - an act declaring assertion of authority by the sovereign, the bay shall be treated like the other internal waters; - public declaration of the assertion of authority made by the government; - effective exercise of the authority: if an action needs to be taken to defend the claim, it shall have been taken;
- a long and *continuous usage*. Both the considerable length of the period of exercise of sovereignty and of the actual usage activity during this period are important;
- *acquiescence* of foreign states, understood as inaction of other states with respect to the claim.[9]

The ancient title, unlike the historic title, is not adverse, as by definition no other states were dispossessed at the time of the claim.[10] The requirements of proof are thus lower. The sovereign needs to show that:[11]

- it was the first sovereign to claim the particular area and
- the area was effectively occupied (to the standards of the time) prior to the acceptance of the freedom of high seas doctrine.
