Phase I: Territorial Sovereignty and Scope of Dispute

CHAPTER IV – Historic Title and Other Historical Considerations

114. Article 2 of the Agreement for Arbitration enjoins the Tribunal to decide territorial sovereignty in accordance with applicable international law "and on the basis, in particular, of historic title." The Tribunal has thus paid particular attention both to the arguments relating to ancient titles and reversion thereof proposed by Yemen and arguments relating to longstanding attribution of the Mohabbakahs to the colony of Eritrea and to early establishment of titles by Italy pronounced by Eritrea. An important element of Yemen's case is that of an asserted "historic title" to the Islands, and this is indeed reflected in the very language of both the Agreement on Principles and the Arbitration Agreement. Thus the Tribunal fully recognises that the intention of Article 2 is that, among all the relevant international law, particular attention should be accorded to such elements. Notwithstanding its analysis of how the principles, rules and practices of international law generally bear on its decision on territorial sovereignty, the Tribunal has had the most careful regard to historic titles as they bear on this case.

115. For its part, Eritrea makes no argument for sovereignty based on ancient title, in spite of the undeniable antiquity of Ethiopia. Rather, Eritrea in part asserts an historic consolidation of title on the part of Italy during the inter-war period that resulted in a title to the Islands that became effectively transferred to Ethiopia as a result of the territorial dispositions after the defeat of Italy in the Second World War. This argument will naturally fall to be dealt with in the chapters below dealing with the inter-war periods and the armistice and related proceedings at the end of the Second World War.

116. Yemen has asserted an historic or "ancient title" running back in time to the middle ages, under which the islands are asserted to have formed part of the Bilad el-Yemen. This ancient title predated the several occupations by the Ottoman Empire, asserts Yemen, and reverted to modern Yemen after the collapse of the Ottoman Empire at the end of the First World War.

117. It is thus only Yemen that has raised substantial questions of an "historic" or "ancient" title that existed before the second Ottoman occupation of the nineteenth century; it is therefore to an appreciation of the historical background necessary for an understanding of that claim to an early title that the Tribunal now turns. This chapter will consider the ways in which the overall history of the Arabian peninsula must be understood in then contemporary legal terms, as a preface to the Tribunal's ultimate conclusion on the legal questions concerning "historic titles". In addition, this chapter will address Yemen's theory of "reversion," which is critical to any decision as to the legal effect of an "historic title."

118. Yemen's arguments on historic and ancient title touch upon several important historical considerations. One relates to the identity of historic Yemen and whether it comprised the islands in dispute. A second questions the existence of a doctrine of reversion recognized in international law, and a third relates to the place of continuity within a concept of reversion of ancient title. Those claims advanced by Eritrea that are based on both history and international law are addressed elsewhere. This chapter further addresses such important historical matters as the tradition of joint use of the Islands' waters by fishermen from both sides of the Red Sea, and the Ottoman allocation of administrative jurisdiction between the two coasts.

119. Yemen's claim is based essentially on an "ancient" or "historical" title pursuant to which the Imam's inherent and inalienable sovereignty extended over the entirety of what historically has been known as Bilad el-Yemen, which existed for several centuries and is alleged by Yemen to have included the southern Red Sea islands. This sovereignty is further characterized by Yemen as having remained unaffected by and having survived the Ottoman annexation of Yemen, in spite of the Sublime Porte's having declared Yemen to be one of the vilayets falling under Ottoman rule.

120. The arguments advanced by Yemen in this respect must be evaluated within the historical and legal context that prevailed during the relevant period, extending from the end of the 19th Century until the dissolution of the Ottoman Empire.

121. The particularity of the relationship between the Ottoman Empire and Yemen should be taken into account as an important historical factor. In spite of the Treaty of Da'an, concluded in 1911, which granted the Imam of Yemen a greater degree of internal autonomy, he remained a suzerain acting within Ottoman sovereignty until the total disintegration of the Ottoman Empire and the loss of all its Arabian possessions, including the vilayet of Yemen.(9) It was only in 1923, by virtue of Article 16 of the Treaty of Lausanne, that the Ottoman Empire not only recognized the renunciation of all its sovereignty rights over Yemen, but explicitly renounced its sovereign title over the islands that had previously fallen under the jurisdiction of the Ottoman wali in Hodeidah.

122. The territorial extent of Imamic Yemen as an autonomous entity must be distinguished from that of the Ottoman vilayet of Yemen. During the entire period from the second half of the 19th Century until 1925, the Imam of Yemen had neither sovereignty nor jurisdiction over the Tihama and the Red Sea coasts. Under his agreements with the Ottoman sultan, the Imam administered an exclusively land-locked territory, limited to the high mountains. The Ottoman wali exercised exclusive jurisdiction over the coasts until 1917. Thereafter, the coasts came under the control of the Idrisi, a local tribal ruler supported first by the Italians, and later by the British Government. The coast came under the Imam's rule only in 1926. As will be seen later, this fact has negative legal implications for the "reversion" argument advanced by Yemen, as well as for the application of certain other rules of international law, including the concept of ancient "historic title" in its full classical sense.

123. There can be no doubt that the concept of historic title has special resonance in situations that may exist even in the contemporary world, such as determining the sovereignty over nomadic lands occupied during time immemorial by given tribes who owed their allegiance to the ruler who extended his socio-political power over that geographic area. A different situation exists with regard to uninhabited islands which are not claimed to be falling within the limits of historic waters.

124. In the present case, neither party has formulated any claim to the effect that the disputed islands are located within historic waters. Moreover, none of the Islands is inhabited on other than a seasonal or temporary basis, or even has the natural and physical conditions that would permit sustaining continual human presence. Whatever may have been the links between the coastal lands and the islands in question, the relinquishment by the Ottoman Empire of its sovereignty over the islands by virtue of Article 16 of the 1923 Treaty of Lausanne (discussed in greater detail in Chapter V) logically and legally adversely affects any pre-existing title.

125. It was recognized in the course of the oral hearings that, by the law in force at the time, Ottoman sovereignty over the regions in question was lawful. The fact that Yemen was not a party to the Treaty of Lausanne, and that it perceived both the British and the Italians as having been usurpers in the Red Sea, does not negate that legal consequence. It has not been established in these proceedings to the satisfaction of the Tribunal that the doctrine of reversion is part of international law. In any event, the Tribunal concludes that on the facts of this case it has no application. No "reversion" could possibly operate, since the chain of titles was necessarily interrupted and whatever previous merits may have existed to sustain such claim could hardly be invoked. During several decades, the predominant role was exercised by the western naval powers in the Red Sea after its opening to international maritime traffic through the Suez Canal, as well as through the colonization of the southern part of the Red Sea on both coasts. An important result of that hegemony was the maintenance of the status quo imposed after the First World War, in particular that the sovereignty over the islands covered by Article 16 of the Lausanne Treaty of 1923 remained indeterminate at least as long as the interested western powers were still in the region. As long as that colonial situation prevailed, neither Ethiopia nor Yemen was in a position to demonstrate any kind of historic title that could serve as a sufficient basis to confirm sovereignty over any of the disputed islands. Only after the departure of the colonial powers did the possibility of a change in the status quo arise. A change in the status quo does not, however, necessarily imply a reversion.

126. This should not, however, be construed as depriving historical considerations of all legal significance. In the first place, the conditions that prevailed during many centuries with regard to the traditional openness of southern Red Sea marine resources for fishing, its role as means for unrestricted traffic from one side to the other, together with the common use of the islands by the populations of both coasts, are all important elements capable of creating certain "historic rights" which accrued in favour of both parties through a process of historical consolidation as a sort of "servitude internationale" falling short of territorial sovereignty.(10) Such historic rights provide a sufficient legal basis for maintaining certain aspects of a res communis that has existed for centuries for the benefit of the populations on both sides of the Red Sea. In the second place, the distinction in terms of jurisdiction which existed under the Ottoman Empire between those islands administered from the African coast and the other islands administered from the Arabian coast constitutes a historic fact to be taken into consideration.

127. According to the most reliable historical and geographical sources, both ancient and modern, the reported data clearly indicate that the population living around the southern part of the Red Sea on the two opposite coasts have always been inter-linked culturally and engaged in the same type of socio-economic activities. Since times immemorial, they were not only conducting exchanges of a human and commercial nature, but they were freely fishing and navigating throughout the maritime space using the existing islands as way stations (des îles relais) and occasionally as refuge from the strong northern winds. These activities were carried out for centuries without any need to obtain any authorizations from the rulers on either the Asian or the African side of the Red Sea and in the absence of restrictions or regulations exercised by public authorities.

128. This traditionally prevailing situation reflected deeply rooted cultural patterns leading to the existence of what could be characterized from a juridical point of view as res communis permitting the African as well as the Yemeni fishermen to operate with no limitation throughout the entire area and to sell their catch at the local markets on either side of the Red Sea. Equally, the persons sailing for fishing or trading purposes from one coast to the other used to take temporary refuge from the strong winds on any of the uninhabited islands scattered in that maritime zone without encountering difficulties of a political or administrative nature.(11)

129. These historical facts are witnessed through a variety of sources submitted in evidence during the arbitral proceedings. A comprehensive evaluation of the evidence submitted by both Parties reveals the presence of deeply-rooted common patterns of behaviour as well as the continuation, even in recent years, of cross-relationships which are marked by eventual recourse to professional fishermen's arbitrators (aq'il) in charge of settling disputes in accordance with the local customary law. Such understanding finds support in the statements attributed to fishermen from both coasts of the Red Sea, taken as a whole, which have been submitted by both Parties.

130. The socio-economic and cultural patterns described above were perfectly in harmony with classical Islamic law concepts, which practically ignored the principle of "territorial sovereignty" as it developed among the European powers and became a basic feature of 19th Century western international law.(12)

131. However, it must be noted that the Ottoman Empire, which directly or through its suzerains governed the quasi-totality of the countries around the Red Sea during the first half of the 19th Century including Bilad El-Yemen and what became known thereafter as Eritrea, started after the end of the Crimean War in 1856 to abandon the communal aspects of the Islamic system of international law and to adopt the modern rules prevailing among the European concert of nations to which the Sublime Porte became a fully-integrated party during the Berlin Congress of 1875. According to this new modern international law, the legal concept of "territorial sovereignty" became a cornerstone for most of the state powers, and the situation in the Red Sea could no longer escape the juridical consequences of that new reality.

132. Hence, it is understandable that both Parties are in agreement that the islands in dispute initially all fell under the territorial sovereignty of the Ottoman Empire. Within the exercise of the Ottoman's sovereignty over these islands, it has to be noted that the Sublime Porte granted to the Khedive of Egypt the right to administer the Ottoman possessions (vilayet) on the African Coast which at present form "the State of Eritrea", and this delegation of power included jurisdiction over islands off the African Coast, including the Dahlaks and eventually the Mohabbakahs.

133. The sovereignty of the Ottoman Empire over both coasts of the Red Sea is undisputed up to 1880 and this remained the case with regard to the eastern, or Arabian, coast until the First World War. Among the various documents introduced in support of this historical fact, Eritrea has submitted the French-language version of a memorandum dated 6 December 1881, issued by the Egyptian Khedival Ministry of Foreign Affairs, which indicates that in May 1871, Italy recognised that the Ottoman flag had been flying since 1862 over the African Coast at a point going beyond the south of Assab. The Egyptian memorandum added that until 1880 the Egyptian Government believed the affirmation of the Italian Government that the Italian presence had been essentially of private and commercial character. Consequently, the entire African coast and the islands off that coast remained until then under the Khedive's jurisdiction. At the same time, all other islands were, and continued to be, under the jurisdiction of the Ottoman wali stationed in Hodeidah and appointed by the Sublime Porte.

134. Hence, a clear distinction has to be made between the Red Sea islands which were under jurisdiction of the Khedive of Egypt acting on behalf of the Ottoman Empire until 1882 and the other Red Sea islands which remained under the Ottoman vilayet of Yemen until the dissolution of the Empire after the First World War.

135. A British Foreign Office Memorandum dated 10 June 1930, relying expressly on the Hertslet memorandum of 1880, indicates that the Khedive of Egypt exercised jurisdiction off the African coast over the "Mohabakah Islands, Harbi and Sayal". With regard to the other category, the British Memorandum describes "the Great Hanish group as being off the Arabic Coast and consequently under the sovereignty and within the exclusive jurisdiction of the Sultan".

Paragraph 16 of the same Memorandum emphasised that:

Great Hanish, Suyal Hanish, Little Hanish, Jebal Zukur, Abu Ail, being nearer to the Arabian Coast, appear before the war to have been considered as under both the jurisdiction and sovereignty of Turkey.

136. Furthermore, Eritrea has submitted Italian Colonial Ministry documents, including a note dated October 11, 1916, entitled "The Red Sea Islands", reflecting the findings of an inquiry conducted on the islands themselves. After devoting Part I to "Farsan" and Part II to "Kameran", Part III of the note deals with "the other islands", which included what is referred to as "Gebel Zucur". This heading included not only the "group of 12 sizeable rocks", but also "the two great and small Hanish islands". With regard to these islands, it was noted that "[t]he Ottoman authorities kept a small garrison of 40 there under the command of a Mulazim to monitor the movement of importation vessels to the Yemen Coast from Gibut.", and further that, "faced with the difficulties of supplying water and victuals on account of a shortage of resources, the Ottoman authorities withdrew the garrison." After the bombardment of Midi by Italian warships, the Ottoman authorities are said to have "restored the garrison in 1909 and increased the number of askaris to 100."

137. These Italian colonial documents, which confirm Ottoman sovereignty over the Hanish-Zuqar islands and assert that they continued in 1916 to be administered by the vilayet of Yemen, are consistent with the views expressed in a telegram addressed by the Governor of the Eritrean Colony to the Italian Minister of the Colonies and transmitted on October 18, 1916 to the Italian Minister of Foreign Affairs. A Foreign Ministry note entitled: "The Red Sea Islands", dating back to July 31, 1901, is attached thereto as "Appendix II". The 1901 Note bases the division of the islands into three groups:

The most northerly islands, which are of little or almost no relation to the Colony of Eritrea on account of the distance, those facing Massaua and the most southerly islands which are opposite the Eritrean Coasts of Beilul and Assab. Almost all are found on the eastern coast of the Red Sea, except the Dahalac islands, which are under our rule, and a few others of much less importance.

With regard to the second group, the Italian note indicates:

Leaving aside the archipelago of the Dahalac islands B which is under the sovereignty of Italy and which include the biggest islands in the Red Sea B Cotuma, Diebel Tair and Camaran are notable in this second group of the archipelago; all of which under Turkish rule.

The note explicitly characterizes as "Turkish": "Cotuma", "Djebel. . . called Gebel Sebair" and "Camaran".
Turning to the third group, the 1901 Italian note refers to a:

. . . group of islands known as Hanish or Harnish (Turkish). It comprises the island of Gebel Zucar, large and small Hanish islands and the other minor islands of Abu-ail, Syul-Hanish, Haycoc and Mohabbach, and a few islets amounting to large rocks.

138. Contemporary British documents also reflect the view that the islands in question, with the exception of Mohabbakahs, formed part of the vilayet of Yemen, and appear to link their future disposition to this historical attachment to the Arabian Coast.

139. A Foreign Office Memorandum dated 15 January 1917 and entitled "Italy and the Partition of the Turkish Empire" provides in paragraph 38:

Lastly, everyone seems to be agreed that the islands in the Red Sea which were previously under Turkish sovereignty pass naturally to the Arab State, though some special regime will be necessary in Kamaran Island in view of the pilgrim traffic.

140. Lord Balfour, in a 13 March 1919 letter to Lord Curzon, indicated that the solution envisaged for "Abu Ail, Zabayir and Jebel Teir" as well as "Kamaran, Zukur and the Hanish Islands (Great Hanish, Little Hanish and Suyul Hanish group)" was either "to annex them" to the British Empire or "to claim that they should be handed over to some independent Arab rulers on the mainland other than the Imam of Sanaa or the Idrisi".

141. Lord Curzon's letter addressed to Lord Balfour on 27 May 1919 linked the subject of any handover to Arab rulers with the essentially political question of the area's future, "the whole question of the future of the Red Sea Islands" was to be considered "ultimately bound with that of the future status of Arabia". Therefore, Lord Curzon indicated that:

[t]he policy of his Majesty's Government should in the first place be directed towards the recognition by the High Contracting Parties of the fact that the islands form a part of the mainland and will accordingly become the property of the Arabian rulers concerned; and that these rulers are to be in special relation with His Majesty's Government.

142. As will be expanded upon later, the allocation of administrative powers over the Red Sea islands, whether by the Ottoman Empire acting as sovereign power on both coasts or only as exercising jurisdiction from the Arabian Coast alone, represents an historic fact that should be taken into consideration and given a certain legal weight.

143. Before leaving this study of the historical considerations, it is necessary to recall the question of ancient or historic Yemeni title, to which Yemen gave such crucial importance in the presentation of its case. It has been explained in this chapter that there are certain historical problems about this argument. First, there is the historical fact that medieval Yemen was mainly a mountain entity with little sway over the coastal areas, which were essentially dedicated to serving the flow of maritime trade between, on the one hand, India and the East Indies, and on the other, Egypt and the other Mediterranean ports. Second, the concept of territorial sovereignty was entirely strange to an entity such as medieval Yemen. Indeed, the concept of territorial sovereignty in the terms of modern international law came late (not until the 19th Century) to the Ottoman Empire, which claimed, and was recognized as having, territorial sovereignty over the entire region.

144. But there are other problems with the Yemeni claim to an ancient title, in particular the effect of Article 16 of the Treaty of Lausanne and the necessity of establishing some doctrine of continuity of ancient title and of reversion at the end of the Ottoman Empire. This subject is explored in detail in the following chapter, and the final view of the Tribunal on this question of ancient title is expressed in Chapter X.
