Geography and Location
Eritrea is a country in the Horn of Africa region of East Africa. Its capital and largest city is Asmara. The country is bordered by Ethiopia to the south, Sudan to the west, and Djibouti to the southeast. The northeastern and eastern parts of Eritrea have an extensive coastline along the Red Sea. The country has a total area of approximately 117,600 km² (45,406 sq mi), and includes the Dahlak Archipelago and several of the Hanish Islands.
Etymology
The name Eritrea is derived from the ancient Greek name for the Red Sea, the Erythraean Sea, based on the adjective "erythros," which means "red." It was first formally adopted in 1890 with the formation of Italian Eritrea. The name persisted throughout subsequent British and Ethiopian occupation and was reaffirmed by the 1993 independence referendum and 1997 constitution.
Prehistory and Early Human History
Eritrea holds significant importance in understanding human evolution. Hominid remains found in Eritrea have been dated to 1 million years old. A fossil known as Madam Buya, discovered at an Eritrean archaeological site by Italian anthropologists, is among the oldest hominid fossils found to date and is believed to reveal significant stages in human evolution, representing a possible link between Homo erectus and archaic Homo sapiens.
During the last interglacial period (roughly 130,000 to 115,000 years ago), the Red Sea coast of Eritrea was occupied by early anatomically modern humans. In 1999, the Eritrean Research Project Team discovered a Paleolithic site near the Gulf of Zula with stone and obsidian tools dated to more than 125,000 years old, believed to have been used by early humans to harvest marine resources.
Ancient Kingdoms and Civilizations
Tools found in the Barka Valley dating from 8,000 BC offer the first concrete evidence of human settlement in the area. Around 2,000 BC, parts of Eritrea were likely part of the Land of Punt, a kingdom known for producing and exporting gold, aromatic resins, blackwood, ebony, ivory, and wild animals.
Dʿmt was a kingdom that existed from the tenth to fifth centuries BC in what is now Eritrea and northern Ethiopia. Evidence of a massive temple complex at Yeha suggests it was most likely Dʿmt's capital. The realm developed irrigation schemes, used plows, grew millet, and made iron tools and weapons.
The Kingdom of Aksum was a trading empire centered in Eritrea and northern Ethiopia that existed from approximately 100–940 AD. By the first century AD, it had achieved prominence and was considered one of the four great powers of the world by the Persian prophet Mani, founder of Manichaeism. Under Ezana (fl. 320–360), Aksum adopted Christianity around the middle of the fourth century, making Christianity the first world religion adopted in modern Eritrea.
Medieval and Ottoman Periods
Beginning in the 12th century, the Zagwe and Solomonid dynasties held fluctuating control over the entire plateau and the Red Sea coast. Eritrea's central highlands, known as Mereb Melash ("Beyond the Mereb"), were the northern frontier region of the Ethiopian kingdoms and were ruled by a governor titled the Bahr Negus ("King of the Sea").
In the 16th century, the Ottoman Empire attempted to conquer the highlands for decades but eventually failed. They were forced to offer a peace treaty that limited them to the Eritrean coastline.
Colonial Period and Independence
In May 1865, much of the coastal lowlands came under the rule of the Khedivate of Egypt until it was transferred to Italy in February 1885. Beginning in 1885–1890, Italian troops systematically spread out from Massawa toward the highlands, eventually resulting in the formation of the colony of Italian Eritrea in 1889, establishing the present-day boundaries of the country. Italian rule continued until 1942, when Eritrea was placed under British Military Administration during World War II.
Following a UN General Assembly decision in 1952, Eritrea was granted local self-governance with a local Eritrean parliament, but entered into federal status with Ethiopia for foreign affairs and defense for ten years. However, in 1962, the government of Ethiopia annulled the Eritrean parliament and formally annexed Eritrea.
The Eritrean secessionist movement organized the Eritrean Liberation Front in 1961 and fought the Eritrean War of Independence until Eritrea gained de facto independence in 1991. Eritrea gained de jure independence in 1993 after an independence referendum.
Modern Eritrea
Population and Languages
Contemporary Eritrea is a multi-ethnic country with nine recognized ethnic groups, each with a distinct language. The most widely spoken language is Tigrinya. The others are Tigre, Saho, Kunama, Nara, Afar, Beja, Bilen, and Arabic. Tigrinya, Arabic, and English serve as the three working languages. Most residents speak languages from the Afroasiatic family, either from the Ethiopian Semitic languages or Cushitic branches.
Ethnic Tigrinyas make up about 50% of the population, with the Tigre people constituting around 30% of inhabitants. There are also several Nilo-Saharan-speaking Nilotic ethnic groups. Most people in the country adhere to Christianity or Islam, with a small minority adhering to traditional faiths.
Government and Politics
Eritrea is a unitary one-party presidential republic and a de facto totalitarian dictatorship in which national legislative and presidential elections have never been held. Isaias Afwerki has served as president since its official independence in 1993. The country's human rights record is among the worst in the world, though the Eritrean government has dismissed these allegations as politically motivated.
Eritrea is a member of the African Union and the United Nations and serves as an observer state in the Arab League alongside Brazil and Venezuela. It was part of the Intergovernmental Authority on Development until withdrawing in December 2025.
Cultural Heritage
Asmara, the capital city, was designated a World Heritage Site in 2017 for its well-preserved Italian modernist architecture.
