paragraph_text: During the Middle Ages, the Eritrea region was known as Medri Bahri ("sea-land"). The name Eritrea is derived from the ancient Greek name for Red Sea (Ἐρυθρὰ Θάλασσα Erythra Thalassa, based on the adjective ἐρυθρός erythros "red"). It was first formally adopted in 1890, with the formation of Italian Eritrea (Colonia Eritrea). The territory became the Eritrea Governorate within Italian East Africa in 1936. Eritrea was annexed by Ethiopia in 1953 (nominally within a federation until 1962) and an Eritrean Liberation Front formed in 1960. Eritrea gained independence following the 1993 referendum, and the name of the new state was defined as State of Eritrea in the 1997 constitution.[citation needed]

paragraph_text: The earliest known cave paintings / drawings of animals are at least 35,000 years old and were found in caves in the district of Maros, located in Bantimurung district, South Sulawesi, Indonesia, according to datings announced in 2014. Previously it was believed that the earliest paintings were in Europe. The earliest figurative paintings in Europe date back to the Aurignacian period, approximately 30,000 to 32,000 years ago, and are found in the Chauvet Cave in France, and in the Coliboaia Cave in Romania. The earliest non-figurative rock art dates back to approximately 40,000 years ago, the date given both to a disk in the El Castillo cave and a hand stencil in Timpuseng cave Sulawesi, Indonesia. There are similar later paintings in Africa, Australia and South America, continuing until recent times in some places, though there is a worldwide tendency for open air rock art to succeed paintings deep in caves.

paragraph_text: Somali people in the Horn of Africa are divided among different countries (Somalia, Djibouti, Ethiopia, and northeastern Kenya) that were artificially and some might say arbitrarily partitioned by the former imperial powers. Pan-Somalism is an ideology that advocates the unification of all ethnic Somalis once part of Somali empires such as the Ajuran Empire, the Adal Sultanate, the Gobroon Dynasty and the Dervish State under one flag and one nation. The Siad Barre regime actively promoted Pan-Somalism, which eventually led to the Ogaden War between Somalia on one side, and Ethiopia, Cuba and the Soviet Union on the other.

paragraph_text: According to an autosomal DNA study by Hodgson et al. (2014), the Afro-Asiatic languages were likely spread across Africa and the Near East by an ancestral population(s) carrying a newly identified non-African genetic component, which the researchers dub the "Ethio-Somali". This Ethio-Somali component is today most common among Afro-Asiatic-speaking populations in the Horn of Africa. It reaches a frequency peak among ethnic Somalis, representing the majority of their ancestry. The Ethio-Somali component is most closely related to the Maghrebi non-African genetic component, and is believed to have diverged from all other non-African ancestries at least 23,000 years ago. On this basis, the researchers suggest that the original Ethio-Somali carrying population(s) probably arrived in the pre-agricultural period from the Near East, having crossed over into northeastern Africa via the Sinai Peninsula. The population then likely split into two branches, with one group heading westward toward the Maghreb and the other moving south into the Horn.

paragraph_text: Ottoman Turkish was the official language of the Empire. It was an Oghuz Turkic language highly influenced by Persian and Arabic.

In the last two centuries, usage of these became limited, though, and specific: Persian served mainly as a literary language for the educated, while Arabic was used for religious rites.

Other subspecies live currently in grasslands south of the Sahara, from Senegal in the west to Eritrea and Ethiopia in the east and down to central Tanzania. The red hartebeest and Lichtenstein's hartebeest, alternatively considered subspecies or sister species of the common hartebeest, are present in southern Africa.

paragraph_text: The birth of Islam on the opposite side of Somalia's Red Sea coast meant that Somali merchants, sailors and expatriates living in the Arabian Peninsula gradually came under the influence of the new religion through their converted Arab Muslim trading partners. With the migration of fleeing Muslim families from the Islamic world to Somalia in the early centuries of Islam and the peaceful conversion of the Somali population by Somali Muslim scholars in the following centuries, the ancient city-states eventually transformed into Islamic Mogadishu, Berbera, Zeila, Barawa and Merca, which were part of the Berberi civilization. The city of Mogadishu came to be known as the City of Islam, and controlled the East African gold trade for several centuries.

paragraph_text: In the late 19th century, after the Berlin conference had ended, European empires sailed with their armies to the Horn of Africa. The imperial clouds wavering over Somalia alarmed the Dervish leader Mohammed Abdullah Hassan, who gathered Somali soldiers from across the Horn of Africa and began one of the longest anti-colonial wars ever. The Dervish State successfully repulsed the British empire four times and forced it to retreat to the coastal region. As a result of its successes against the British, the Dervish State received support from the Ottoman and German empires. The Turks also named Hassan Emir of the Somali nation, and the Germans promised to officially recognize any territories the Dervishes were to acquire. After a quarter of a century of holding the British at bay, the Dervishes were finally defeated in 1920, when Britain for the first time in Africa used airplanes to bomb the Dervish capital of Taleex. As a result of this bombardment, former Dervish territories were turned into a protectorate of Britain. Italy similarly faced the same opposition from Somali Sultans and armies and did not acquire full control of parts of modern Somalia until the Fascist era in late 1927. This occupation lasted till 1941 and was replaced by a British military administration.
