Question: When was Eritrea annexed by the Horn of Africa country that, along with Kenya, Somalia, and the citizenship country of Zourah Ali, is one of the places where Somalis live?

<P0-S0> Zourah Ali (born 23 November 1994 in Ali Sabieh, Djibouti) is a Djiboutian runner. <P0-S1> She competed at the 2012 Summer Olympics in the 400m event, which she completed in 1:05.37 minutes. <P0-S2> She did not place high enough in her heat to be qualified to the semifinals as she finished in 44th place and with the second slowest time in that race. <P0-S3> After the Olympics, Zourah was sponsored by the Republican Guard, which is the branch of military that guards the president. <P0-S4> Zourah was the only female athlete for the Republican Guard for a period of time, but with the addition of athletes such as Kadra Mohamed Dembil, they expanded their female team. <SEP> <P1-S0> During the Middle Ages, the Eritrea region was known as Medri Bahri ("sea-land"). <P1-S1> The name Eritrea is derived from the ancient Greek name for Red Sea (Ἐρυθρὰ Θάλασσα Erythra Thalassa, based on the adjective ἐρυθρός erythros "red"). <P1-S2> It was first formally adopted in 1890, with the formation of Italian Eritrea (Colonia Eritrea). <P1-S3> The territory became the Eritrea Governorate within Italian East Africa in 1936. <P1-S4> Eritrea was annexed by Ethiopia in 1953 (nominally within a federation until 1962) and an Eritrean Liberation Front formed in 1960. <P1-S5> Eritrea gained independence following the 1993 referendum, and the name of the new state was defined as State of Eritrea in the 1997 constitution. <P1-S6> [citation needed] <SEP> <P2-S0> djibouti ( (listen) jih-boo-tee; afar: yibuuti, arabic: جيبوتي‎ jībūtī, french: djibouti, somali: jabuuti, officially the republic of djibouti) is a country located in the horn of africa. <P2-S1> it is bordered by eritrea in the north, ethiopia in the west and south, and somalia in the southeast. <P2-S2> the remainder of the border is formed by the red sea and the gulf of aden at the east. <P2-S3> djibouti occupies a total area of 23,200 km2 (8,958 sq mi). <P2-S4> the state of djibouti is predominantly inhabited by two ethnic groups, the somali and the afar people, the somalis being the major ethnic group of the country. <SEP> <P3-S0> dolo addo or dolo ado or dollo ado () is one of the woredas in the somali region of ethiopia. <P3-S1> part of the liben zone, dolo ado is located in the angle formed by the confluence of the ganale dorya with the dawa river, and bordered to the northwest by filtu, on the northeast by afder zone, on the southeast by somalia, and on the south by kenya. <P3-S2> towns in dollo ado include bekol may, dolo and softu. <SEP> <P4-S0> 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. <P4-S1> 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. <P4-S2> 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.
