a referendum. This referendum was held in April 1993, and the vote was overwhelmingly in favour of independence, leading to the establishment of a new state joining the United Nations. Also in 1991, the transitional government of Eritrea and the TPLF-led transitional government of Ethiopia agreed to set up a commission, to look into any problems that arose between the two former wartime allies over the foreseen independence of Eritrea. This commission was not successful, and during the following years relations between the governments of the two sovereign states deteriorated. Eritrea soon began a practice of forcibly expelling Ethiopians from its territory. As early as 1991, about 30,000 wives and children of Ethiopian soldiers stationed in Eritrea were bused by Eritrean forces across the border, and crowded into camps in Adigrat, Adwa and Axum, with the EPLF telling relief officials to expect 150,000 more Ethiopian civilians. Reportedly, many of the deportees were people who were being dismissed from their jobs, some of them longtime residents of Eritrea. Determining the border between the two states also became a major source of conflict. In November 1997, a committee was set up to try to resolve it. Before Eritrean independence, the border had been of minor importance, as it was only a demarcation line between federated provinces, and initially, the two governments tacitly agreed that the border should remain as it had been immediately before independence. Upon independence, however, the border became an international frontier, and the two governments could not agree on where, specifically, the border should be demarcated; they looked back to colonial-era treaties between the Italian Empire and Ethiopia as a basis for the precise boundaries between the states. Problems then arose, because they could not agree on the interpretation of those agreements and treaties, and it was not clear, under international law, how binding colonial treaties were on the two states. Analysis Writing after the war had finished, Jon Abbink postulated that President Isaias Afewerki of Eritrea realised that his influence over the government in Ethiopia was slipping, and "in the absence of a concrete border being marked," calculated that Eritrea could annex Badme. If successful, this acquisition could have been used to enhance his reputation and help maintain Eritrea's privileged economic relationship with Ethiopia. However, because Badme was in Tigray Province – the region from which many of the members of the Ethiopian government originated (including Meles Zenawi,
