Eritrea–Ethiopia relations

Relations between Eritrea and Ethiopia have been historically adversarial. Eritrea gained independence from Ethiopia in 1993 after the Eritrean War of Independence, after which relations were cordial. Since independence Eritrea's relationship with Ethiopia was entirely political, especially in the resuscitation and expansion of IGAD's scope. However, the 1998 Eritrean–Ethiopian War marked a turning point, and their relationship became increasingly hostile.

Upon the selection of Abiy Ahmed as Ethiopian Prime Minister, a peace agreement was forged, and ties between the neighbouring countries were re-established on 9 July 2018. The alliance between the two countries was strengthened in 2020 with Eritrean troops reportedly assisting the Ethiopian Army in the Tigray Conflict, but have since deteriorated as Eritrea has backed Somalia during the current escalations of the Ethiopian–Somali conflict.
