Relations between Somaliland and Ethiopia date back at least to the period or empire of the Adal Sultanate and Abyssinia. The relationship between the two polities was often tense, culminating in the 16th century with the inconclusive Ethiopian–Adal war.[5][6]
The Ethiopian Empire signed a number of treaties with the British government during the period of the British Mandate over Somaliland. The most famous of these treaties is the Anglo-Ethiopian Treaty of 1897, which was aimed at demarcating the border between Ethiopia and Somaliland.[7] The agreement also established the freedom of trade and movement between the two sides.
In 1994, Ethiopia and Somaliland reached security and trade agreements that provided for an expanded strategic partnership. Among the most important of the agreements was a treaty providing for non-formal diplomatic relations between the two countries. Ethiopia and Somaliland also signed an extradition treaty.[10]
On 1 January 2024, Ethiopia and Somaliland signed a memorandum of understanding giving Ethiopia access to the Red Sea via the port of Berbera in return for recognizing Somaliland.[11][12]
