full_context: Document 1: Dera, Amhara (woreda): Dera is one of the woredas in the Amhara Region of Ethiopia. Part of the Debub Gondar Zone, Dera is bordered on the south by the Abbay River which separates it from the Mirab Gojjam Zone, on the west by Lake Tana, on the north by Fogera, on the northeast by Misraq Este, and on the east by Mirab Este. Towns in Dera include Amba Same, Arb Gebeya, Hamusit, and Qorata.
Document 2: Gera (woreda): Gera is one of the woredas in the Oromia Region of Ethiopia. It is named after the former Kingdom of Gera, whose territory was approximately the same as the modern woreda. Part of the Jimma Zone, Gera is bordered on the south by the Gojeb River which separates it from the Southern Nations, Nationalities and Peoples Region, on the northwest by Sigmo, on the north by Setema, on the northeast by Gomma, and on the east by Seka Chekorsa.

Document 3: Somalis: All of these traditions, including festivals, martial arts, dress, literature, sport and games such as Shax, have immensely contributed to the enrichment of Somali heritage.
Document 4: British Empire: While the Suez Crisis caused British power in the Middle East to weaken, it did not collapse. Britain again deployed its armed forces to the region, intervening in Oman (1957), Jordan (1958) and Kuwait (1961), though on these occasions with American approval, as the new Prime Minister Harold Macmillan's foreign policy was to remain firmly aligned with the United States. Britain maintained a military presence in the Middle East for another decade. In January 1968, a few weeks after the devaluation of the pound, Prime Minister Harold Wilson and his Defence Secretary Denis Healey announced that British troops would be withdrawn from major military bases East of Suez, which included the ones in the Middle East, and primarily from Malaysia and Singapore. The British withdrew from Aden in 1967, Bahrain in 1971, and Maldives in 1976.
Document 5: Somalis: The textile-making communities in Somalia are a continuation of an ancient textile industry, as is the culture of wood carving, pottery and monumental architecture that dominates Somali interiors and landscapes. The cultural diffusion of Somali commercial enterprise can be detected in its cuisine, which contains Southeast Asian influences. Due to the Somali people's passionate love for and facility with poetry, Somalia has often been referred to by scholars as a "Nation of Poets" and a "Nation of Bards" including, among others, the Canadian novelist Margaret Laurence.
Document 6: Suez Canal: The Convention of Constantinople in 1888 declared the canal a neutral zone under the protection of the British, who had occupied Egypt and Sudan at the request of Khedive Tewfiq to suppress the Urabi Revolt against his rule. The revolt went on from 1879 to 1882. As a result of British involvement on the side of Khedive Tewfiq, Britain gained control of the canal in 1882. The British defended the strategically important passage against a major Ottoman attack in 1915, during the First World War. Under the Anglo - Egyptian Treaty of 1936, the UK retained control over the canal. The canal was again strategically important in the 1939 -- 1945 Second World War, and Italo - German attempts to capture it were repulsed during the North Africa Campaign, during which the canal was closed to Axis shipping. In 1951 Egypt repudiated the treaty and in October 1954 the UK agreed to remove its troops. Withdrawal was completed on 18 July 1956.
Document 7: Mali: Malian musical traditions are derived from the griots, who are known as "Keepers of Memories". Malian music is diverse and has several different genres. Some famous Malian influences in music are kora virtuoso musician Toumani Diabaté, the late roots and blues guitarist Ali Farka Touré, the Tuareg band Tinariwen, and several Afro-pop artists such as Salif Keita, the duo Amadou et Mariam, Oumou Sangare, and Habib Koité. Dance also plays a large role in Malian culture. Dance parties are common events among friends, and traditional mask dances are performed at ceremonial events.
Document 8: Eritrea: Eritrea's ethnic groups each have their own styles of music and accompanying dances. Amongst the Tigrinya, the best known traditional musical genre is the guaila. Traditional instruments of Eritrean folk music include the stringed krar, kebero, begena, masenqo and the wata (a distant/rudimentary cousin of the violin). The most popular Eritrean artist is the Tigrinya singer Helen Meles, who is noted for her powerful voice and wide singing range. Other prominent local musicians include the Kunama singer Dehab Faytinga, Ruth Abraha, Bereket Mengisteab, Yemane Baria, and the late Abraham Afewerki.
Document 9: British Empire: In 1951, the Conservative Party returned to power in Britain, under the leadership of Winston Churchill. Churchill and the Conservatives believed that Britain's position as a world power relied on the continued existence of the empire, with the base at the Suez Canal allowing Britain to maintain its pre-eminent position in the Middle East in spite of the loss of India. However, Churchill could not ignore Gamal Abdul Nasser's new revolutionary government of Egypt that had taken power in 1952, and the following year it was agreed that British troops would withdraw from the Suez Canal zone and that Sudan would be granted self-determination by 1955, with independence to follow. Sudan was granted independence on 1 January 1956.
Document 10: British Empire: The Suez Crisis very publicly exposed Britain's limitations to the world and confirmed Britain's decline on the world stage, demonstrating that henceforth it could no longer act without at least the acquiescence, if not the full support, of the United States. The events at Suez wounded British national pride, leading one MP to describe it as "Britain's Waterloo" and another to suggest that the country had become an "American satellite". Margaret Thatcher later described the mindset she believed had befallen the British political establishment as "Suez syndrome", from which Britain did not recover until the successful recapture of the Falkland Islands from Argentina in 1982.
Document 11: Shebel Berenta: Shebel Berenta is one of the woredas in the Amhara Region of Ethiopia, named after two older districts which occupy the area this woreda currently covers: Berenta which is north of the Mecha river, and Shebel which is south of that stream. Part of the Misraq Gojjam Zone, Shebel Berenta is bordered on the southwest by Dejen, on the northwest by Enemay, on the north by Enarj Enawga, and on the east by the Abay River which separates it from the Oromia Region. The major town in Shebel Berenta is Yed Wuha.
Document 12: Bahir Dar Zuria: Bahir Dar Zuria (Amharic "Greater Bahir Dar Area") is one of the woredas in the Amhara Region of Ethiopia. Part of the Mirab Gojjam Zone, this woreda is bordered on the south by Yilmana Densa, on the southwest by Mecha, on the northwest by the Lesser Abay River which separates it from Semien Achefer, on the north by Lake Tana, on the shores of Lake Tana situates the city and special zone of Bahir Dar, and on the east by the Abay River which separates it from the Debub Gondar Zone.
Document 13: British Empire: In July 1956, Nasser unilaterally nationalised the Suez Canal. The response of Anthony Eden, who had succeeded Churchill as Prime Minister, was to collude with France to engineer an Israeli attack on Egypt that would give Britain and France an excuse to intervene militarily and retake the canal. Eden infuriated US President Dwight D. Eisenhower, by his lack of consultation, and Eisenhower refused to back the invasion. Another of Eisenhower's concerns was the possibility of a wider war with the Soviet Union after it threatened to intervene on the Egyptian side. Eisenhower applied financial leverage by threatening to sell US reserves of the British pound and thereby precipitate a collapse of the British currency. Though the invasion force was militarily successful in its objectives, UN intervention and US pressure forced Britain into a humiliating withdrawal of its forces, and Eden resigned.
Document 14: Somalis: Somalis have a rich musical heritage centered on traditional Somali folklore. Most Somali songs are pentatonic. That is, they only use five pitches per octave in contrast to a heptatonic (seven note) scale, such as the major scale. At first listen, Somali music might be mistaken for the sounds of nearby regions such as Ethiopia, Sudan or Arabia, but it is ultimately recognizable by its own unique tunes and styles. Somali songs are usually the product of collaboration between lyricists (midho), songwriters (lahan) and singers ('odka or "voice").
Document 15: Dawa Harewa: Dawa Harewa is one of the woredas in the Amhara Region of Ethiopia. Part of the Oromia Zone, Dawa Harewa is bordered on the south by Artuma Fursi, on the west by Dawa Chefe, on the northwest by the Argobba special woreda, on the northeast by Bati, and on the east by the Afar Region. Towns in Dawa Harewa include Bora. Dawa Harewa was part of former Chefe Golana Dewerahmedo woreda.
