conquered by Menelik II of Ethiopia, who solidified their claim by treaties in 1897. I.M. Lewis argues a subtly different interpretation of this treaty, emphasising that "the lost lands in the Haud which were excised from the Protectorate [i.e. British Somaliland] were not, however ceded to Ethiopia". In practice, Ethiopia exerted little administrative control east of Jijiga until 1934 when an Anglo-Ethiopian boundary commission attempted to demarcate the treaty boundary. This boundary is still disputed. In 1914, Lij Iyasu of Ethiopia appointed Abdullahi Sadiq, governor of Ogaden. After the Italian conquest of Ethiopia in 1936, Ogaden was attached to Italian Somaliland, becoming the Somalia Governorate within the new colony of Italian East Africa. Following the British conquest of this colony, the Anglo-Ethiopian Agreement placed Ogaden under temporary British control. The British sought to unite Ogaden with British Somaliland and the former Italian Somaliland to realize Greater Somalia which was supported by many Somalis. Ethiopia unsuccessfully pleaded before the London Conference of the Allied Powers to gain the Ogaden and Eritrea in 1945, but their persistent negotiations and pressure from the United States eventually persuaded the British to cede Ogaden to Ethiopia in 1948. The last remaining British controlled parts of Haud were returned to Ethiopia in 1955. In the late 1970s, internal unrest in the 'Ogaden' resumed. The Western Somali Liberation Front, spurred by Makhtal Dahir, used guerilla tactics to resist Ethiopian rule. Ethiopia and Somalia fought the Ogaden War over control of this region and its peoples. During the new region's founding conference, which was held in Dire Dawa in 1992, the naming of the region became a divisive issue, because almost 30 Somali clans live in the Somali Region of Ethiopia. The ONLF sought to name the region ‘Ogadenia’, whilst the non-Ogadeni Somali clans who live in the same region opposed this move. As noted by Abdul Majid Hussein, the naming of the region where there are several Somali clans as ‘Ogadenia’ following the name of a single clan would have been divisive. Finally, the region was named the Somali region. In 2007, the Ethiopian Army launched a military crackdown in Ogaden after Ogaden rebels killed dozens of civilian staff workers and guards at an Ethiopian oil field. The main rebel group is the Ogaden National Liberation Front under its Chairman Mohamed O. Osman, which is fighting against the Ethiopian government. Some Somalis who inhabit in the 'Ogaden'
