Somaliland, officially the Republic of Somaliland, is an unrecognised sovereign state in the Horn of Africa, internationally considered to be part of Somalia. Somaliland lies in the Horn of Africa, on the southern coast of the Gulf of Aden. It is bordered by Djibouti to the northwest, Ethiopia to the south and west, and Somalia to the east. Its claimed territory has an area of 176,120 square kilometres, with approximately 5.7 million residents as of 2021. The capital and largest city is Hargeisa. The government of Somaliland regards itself as the successor state to British Somaliland, which, as the briefly independent State of Somaliland, united in 1960 with the Trust Territory of Somaliland to form the Somali Republic.
Somaliland was first inhabited around 10,000 years ago during the Neolithic age. The ancient shepherds raised cows and other livestock and it has the most vibrant rock art paintings in Africa. Throughout the Middle Ages, Arab immigrants arrived in Somaliland, a historical experience which would later lead to the legendary stories about Muslim sheikhs such as Daarood and Ishaaq bin Ahmed travelling from Arabia to Somalia and marrying into the local Dir clan.
