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 and includes the Dahlak Archipelago and several of the Hanish Islands. Hominid remains found in Eritrea have been dated to 1 million years old and anthropological research indicates that the area may contain significant records related to human evolution. The Kingdom of Aksum, centred in Eritrea and northern Ethiopia, was established during the first or second century AD and was considered one of the four great powers of the world by Mani, the founder of Manichaeism. It adopted Christianity around the middle of the fourth century. 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 decades long attempt to conquer the Highlands by the Ottomans would result in failure forcing them to offer a peace treaty where they were limited to the Eritrean coastline. 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 would govern itself with a local Eritrean parliament, but for foreign affairs and defense, it would enter into federal status with Ethiopia 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. Contemporary Eritrea is a multi-ethnic country with nine recognized ethnic groups, each of which has 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. In Eritrea, ethnic Tigrinyas make up about 50% of the population, with the Tigre people constituting around 30% of inhabitants. In addition, there are 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. Eritrea is one of the world's least developed countries. It 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. The Eritrean government has dismissed these allegations as politically motivated. Eritrea is a member of the African Union, the United Nations, and is 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, "accusing the organisation of 'becoming a tool against' countries like itself." Asmara was designated a World Heritage Site in 2017 for its well-preserved Italian modernist architecture.
