Borderlines explores the global map, one line at a time.

About 125 millennia ago, the southern end of the strait between Africa and Arabia was much narrower, and may have been the springboard for one of early humanity’s great migratory leaps. [1] A big deal for everyone who has come along since, but the question of where, exactly, those first people out of Africa came from matters immensely to two very antagonistic neighbors. At this moment, in some Internet chat room, the locals are fighting over the nationality of those Red Sea pedestrians: did they originate in Eritrea, or in Ethiopia?

Hyperbole perhaps, but not by much. Few countries harbor as much mutual enmity as Ethiopia and Eritrea (which won its independence over the former in 1993, after a 40-year struggle, by helping to topple Ethiopia’s military junta), and they haggle over the seemingly smallest distinction. Pedigree, both personal and national [2], is a prominent subject in the war of words between these East African nations, across a border that, several years after they stopped fighting, is still “hot,” relatively new and fiercely contested.

The region’s recorded history goes back to 2500 B.C., when it was known to the Egyptians as Punt [3]. In the intervening centuries, countless empires rose and fell, their legacies providing ample ammunition for today’s competing national narratives. Even Balkan grudges, most of them merely centuries old, pale in comparison.

In a region steeped in history, Eritrea’s “newness” is used as an inculpatory argument — proof of its artificiality. Eritrea was a European imperialist creation, the Ethiopian line of reasoning goes, snatched from a united Ethiopian Empire by Italy’s imposition of the Treaty of Wuchale in 1889. The deceptive Article 17 of that treaty [4] led to the First Italo-Ethiopian War, from 1895 to 1896 — and a win for Ethiopia, the only victory of a native African state over a modern European one in modern history.

The resulting Treaty of Addis Ababa, signed in 1896, secured Ethiopia’s independence, but confirmed the loss of Eritrea. How great a loss, though, was never precisely defined. The border between Eritrea and Ethiopia may have been delimitated (i.e., defined by treaty), and subsequently delineated (on maps, at several occasions into the early 20th century), but never even tentatively demarcated (indicated on the ground with markers, signs or fences) [5]. Since Ethiopia effectively absorbed Eritrea after a defeated Italy ceded control of it after World War II, the border wasn’t really an issue. With an armed, independent and unfriendly Eritrea next door, suddenly the border, and Ethiopia’s claim over as much territory as possible, mattered a lot.

The Eritreans neatly reverse the argument. Ethiopia never really “owned” Eritrea; it simply replicated the Italian colonial model. Post-1945, the United Nations mandated federation between Ethiopia and Eritrea, but in 1962, the former proceeded with outright annexation, making the latter its 14th province. The imposition of Amharic, Ethiopia’s lingua franca, in Eritrean schools was not only a blatant example of Ethiopian colonialism, it also helped spark the war that would lead to independence [6], through a referendum supervised by the United Nations.

Despite a brief thawing of relations after Eritrea won its independence, the countries have been at each other’s throats for nearly two decades. You don’t need to take a stand on whether or how much Eritreans and Ethiopians resemble each other to notice a grim symmetry in their relationship. Both countries – democracies in name only [7] – support each other’s opposition movements, and fight a proxy war in Somalia: Eritrea supports the Islamist Shabab militias, while Ethiopia backs the fledgling Transitional Federal Government in Mogadishu.

Most recently, on March 15, 2012, Ethiopia sent troops across the Eritrean border to attack three bases of the Afar Revolutionary Democratic Unity Front [8], allegedly in retaliation for the group’s attacks on a tourist party inside Ethiopia [9]. This fueled fears of a sequel to the bloody Eritrean-Ethiopian war of 1998 to 2000, which cost between 70,000 and 100,000 lives.

That war was not only underreported, but also highly surreal: The linchpin of the conflict was Badme — a town that either doesn’t exist, or is located somewhere else, under another name.

The eponymous plain around the town is “relatively useless borderland” [10] between boundary rivers, the Mareb in the north and the Setit in the south. But it has become symbolic to both sides — a sort of East African Kosovo Polje [11] — because it is where the war started, in May 1998: Ethiopian troops killed some Eritrean soldiers near the border, and Eritrea retaliated by occupying the previously Ethiopian-held town of Badme. If the Eritrean regime had counted on exploiting the vaguely worded Italian-era border delimitations to their advantage, they had forgotten that most of the Ethiopian leadership, including the prime minister, Meles Zenawi, originated in Tigray, the province affected by the occupation.

Ethiopia responded with “total war,” simultaneously attacking on several fronts, and bombarding the airport of Eritrea’s capital Asmara, which invited retaliatory air raids by Eritrea. In a regression from tactics of World War II to those from World War I, the air phase was followed by an intense phase of trench warfare. Thousands died in dusty ditches at Badme and other, smaller disputed areas further east: Tsorone-Zalambessa and Bure. By May 2000, Ethiopia occupied all disputed areas, and about 20 percent of Eritrea’s (uncontested) territory.

Eritrea admitted defeat. But Ethiopia clumsily managed to not capitalize on its victory. The loss of Eritrea in 1993 left Ethiopia bereft of direct access to the sea, and yet the regime in Addis Ababa did not even request access to an Eritrean port as part of an eventual settlement. All it wanted was Badme back.

Incredibly, in its final report in 2002 the Eritrea-Ethiopia Boundary Commission (E.E.B.C.) mentioned Badme just once by name, never even showing it on the map. This is because of confusion over what and where Badme is, exactly. Well south of the disputed border, clearly on the Ethiopian side, is a town called Yirga [12], founded in the 1950s by Ethiopians. The locals call it Badme, and that word is used also to refer to the wider plain on which the town is set. And that plain is divided by the disputed border [13]. In the old Italo-Ethiopian documents, the area remains totally unnamed simply because it was then uninhabited.

The E.E.B.C. reprised a straight line, unilaterally proposed by the Italians, as the international border, slicing off most of the disputed Badme Triangle for Eritrea. Ethiopia’s objections came too late, creating a fait demi-accompli: an international border that is the result of arbitration, but remains disputed by one of the parties involved. Ethiopia still occupies these and other areas that it claims are disputed rather than accorded to Eritrea.

This sounds like a fuse waiting for a fire. So why didn’t Ethiopia’s recent incursion kick off a Second Ethiopian-Eritrean War? Perhaps Eritrea didn’t hit back because the balance of force has tipped further in Ethiopia’s advantage. Ethiopia, with over 80 million inhabitants and a relatively robust economy, is an undisputed regional power. Eritrea, numbering barely 6 million, is suffering under crippling international sanctions imposed for its support of Shabab [14]. Maybe Eritrea is finally too poor, and Ethiopia too rich, to fight over a one-horse town. Or, maybe, the next round of fighting between these two Horn of Africa antagonists is still awaiting the proper spark.

[1] The standard “Out of Africa” hypothesis has a small group of Homo sapiens crossing the Red Sea into the Sinai and thence the rest of Eurasia – a curious prefiguration of the Mosaic trek into the Promised Land, by the way. A second theory explains the peculiarities of mitochondrial DNA distribution throughout the world with a separate, coastal migration from East Africa via Arabia to India. That route remains relevant for today’s migratory flows — increasingly so, in fact: in 2011, more than 100,000 refugees crossed over to Yemen from Africa, double the figure for 2010.

[2] In 2010, Ethiopia’s prime minister, Meles Zenawi, denied rumors that he was a cousin of Isayas Afewerki, the Eritrean president. Zenawi’s Tigrayan People’s Liberation Front (TPLF) and Afewerki’s Eritrean People’s Liberation Front (EPLF) together defeated the Soviet-supported Derg (“committee”) that controlled Addis Ababa in 1991, but fell out soon after Eritrea declared independence in 1993.

[3] The scope of Punt, a source of precious materials and slaves to Pharaonic Egypt, is uncertain, but most definitions include Eritrea. The country’s present name derives from the Greek word for “red,” as in the name of the adjacent sea (Erythra Thalassa: Red Sea). That name may refer to the ancient custom of associating directions with colors. See also footnote [9] of Where Is Europe?

[4] A funny thing happened on the way to the translator. In the Amharic version of Article 17, the treaty merely suggests that Italy can act as an intermediary to the outside world. The Italian version obliges Ethiopia to use Italian mediation, effectively ceding control over its foreign relations to Rome.

[5] Delimitation would become unnecessary, as Italy eventually had its way with Ethiopia. Mussolini defeated Emperor Haile Selassie in the Second Italo-Ethiopian War (1935-1936) and annexing it into Africa Orientale Italiano, comprising present-day Eritrea, Ethiopia and Somalia, minus its northwestern angle (then British Somaliland).

[6] Language education policy may not seem like the stuff revolutions are made of. And yet… In 1976, the introduction of Afrikaans, seen as the language of the white minority, as a compulsory medium of instruction for black students in South Africa led to large-scale riots, which fanned the flames of a protest movement that chipped away at white minority rule, finally ending apartheid in the early 1990s.

[7] Eritrea’s national elections, slated for 2001, were shelved because of the conflict with Ethiopia. No new date has been set. In Ethiopia’s most recent parliamentary elections in 2010, only two out of the total 547 seats were won by candidates not members of or affiliated with the ruling EPRDF party.

[8] If you want to be taken seriously in the world of East African rebel groups, a Group, Organization or even an Army won’t do. You have to be a Front. See also: Eritrean Liberation Front, Eritrean People’s Liberation Front, Front for the Restoration of Unity and Democracy, Islamic Front for the Liberation of Oromia, Ogaden National Liberation Front, Oromo Liberation Front, People’s Front for Democracy and Justice, Somali National Front, Somali Salvation Democratic Front, Tigrayan People’s Liberation Front, Western Somali Liberation Front.

[9] The Afar are a distinct ethnicity, distributed across Djibouti, Eritrea and Ethiopia, where there is an Afar Regional State. The ARDUF rejects attempts at border demarcation between Ethiopia and Eritrea, as this divides the Afar homeland.

[10] Says Jon Abbink in “Badme and the Ethio-Eritrean Border: The Challenge of Demarcation in the Post-War Period,” a fascinating resume of the war and its consequences (or lack thereof).

[11] On this “Blackbird Field” (in Serbo-Croatian) outside Pristina, the Ottomans gained a pyrrhic victory over the Serbs in 1389 — an experience imprinted on the Serbian psyche, informing the aggrieved strand of Serbian nationalism that was instrumental in the Yugoslav wars of the 1990s.

[12] Apparently after Aba Yirga, the favorite horse of Seyoum Mengesha, who founded the village. Perhaps the original one-horse town?

[13] Mr Abbink repeats the suggestion to resolve the by now highly prestigious matter of ownership of Badme by having two towns called Badme. But confuse matters, some maps show a settlement just north of the border (and about 10 miles northwest of Yirga) that is called Badme. Could this whole matter be resolved by officially renaming Yirga into another Badme?

[14] Not that Eritrea treats its own citizens so great. It has the distinction of being the only country in the world to score worse than North Korea on the Press Freedom Index of Reporters Without Borders: in 2010, it came dead last, 178th out of 178 countries.
