Eritrea, officially the State of Eritrea is a country in the Horn of Africa, with its capital at Asmara. It is bordered by Sudan in the west, Ethiopia in the south, and Djibouti in the southeast. The northeastern and eastern parts of Eritrea have an extensive coastline along the Red Sea. The nation has a total area of approximately 117600 km2, and includes the Dahlak Archipelago and several of the Hanish Islands. Its toponym Eritrea is based on the Greek name for the Red Sea (Ἐρυθρὰ Θάλασσα Erythra Thalassa), which was first adopted for Italian Eritrea in 1890.
Eritrea is a multi-ethnic country, with nine recognized ethnic groups in its population of around million. Most residents speak languages from the Afroasiatic family, either of the Ethiopian Semitic languages or Cushitic branches. Among these communities, the Tigrinyas make up about 55% of the population, with the Tigre people constituting around 30% of inhabitants. In addition, there are a number of Nilo-Saharan-speaking Nilotic ethnic minorities. Most people in the territory adhere to Christianity or Islam.
Ethiopia (ኢትዮጵያ, ʾĪtyōṗṗyā,, Tigrinya: ኢትዮጵያ, Oromo: Itiyoophiyaa, Somali: Itoobiya), officially the Federal Democratic Republic of Ethiopia (የኢትዮጵያ ፌዴራላዊ ዲሞክራሲያዊ ሪፐብሊክ, yeʾĪtiyoṗṗya Fēdēralawī Dēmokirasīyawī Rīpebilīk, ), is a country in the northeastern part of Africa, popularly known as the Horn of Africa. It shares borders with Eritrea to the north, Djibouti to the northeast, and Somalia to the east, Sudan to the northwest, South Sudan to the west, and Kenya to the south. With over million inhabitants, Ethiopia is the most populous landlocked country in the world and the second-most populous nation on the African continent that covers a total area of 1,100,000 km2. Its capital and largest city is Addis Ababa, which lies a few miles west of the East African Rift that splits the country into the Nubian Plate and the Somali Plate.
Some of the oldest skeletal evidence for anatomically modern humans has been found in Ethiopia. It is widely considered as the region from which modern humans first set out for the Middle East and places beyond. According to linguists, the first Afroasiatic-speaking populations settled in the Horn region during the ensuing Neolithic era. Tracing its roots to the 2nd millennium BC, Ethiopia's governmental system was a monarchy for most of its history. Oral literature tells that the monarchy was founded by the Solomonic dynasty of the Queen of Sheba, under its first king, Menelik I. In the first centuries AD, the Kingdom of Aksum maintained a unified civilization in the region, followed by the Ethiopian Empire circa 1137. During the late 19th-century Scramble for Africa, Ethiopia was one of two nations to retain its sovereignty from long-term colonialism by a European colonial power. Many newly-independent nations on the continent subsequently adopted its flag colors. The country was occupied by Italy in 1936 and became Italian Ethiopia (part of the Italian East Africa) until 1941. Ethiopia was also the first independent member from Africa of the 20th-century League of Nations and the United Nations. In 1974, the Ethiopian monarchy under Haile Selassie was overthrown by the Derg, a communist military government backed by the Soviet Union. In 1987, the Derg established the People's Democratic Republic of Ethiopia, but it was overthrown in 1991 by the Ethiopian People's Revolutionary Democratic Front, which has been the ruling political coalition since.
