Djibouti, officially the Republic of Djibouti, is a country located in the Horn of Africa. It is bordered by Somaliland in the south, Ethiopia in the southwest, Eritrea in the north, and the Red Sea and the Gulf of Aden in the east. Across the Gulf of Aden is Yemen. The country has a total area of 23,200 km².
In antiquity, the territory together with Ethiopia, Eritrea and Somaliland was part of the Land of Punt. Nearby Zeila, now in Somaliland, was the seat of the medieval Adal and Ifat Sultanates. In the late 19th century, the colony of French Somaliland was established following treaties signed by the ruling Dir Somali sultans with the French and its railroad to Dire Dawa allowed it to quickly supersede Zeila as the port for southern Ethiopia and the Ogaden. It was subsequently renamed to the French Territory of the Afars and the Issas in 1967. A decade later, the Djiboutian people voted for independence. This officially marked the establishment of the Republic of Djibouti, named after its capital city. The new state joined the United Nations the same year, on 20 September 1977.
