The Eritrean–Ethiopian border conflict was a violent standoff between Eritrea and Ethiopia as part of the violence in the Horn of Africa. This included sporadic clashes of their militaries, some of which took part in the larger Second Afar Insurgency. The border conflict had been ongoing since the Eritrean–Ethiopian War of 1998–2000, and included multiple clashes with numerous casualties, such as the 2016 Tserona clashes. Ethiopia eventually stated in 2018 that it would cede Badme to Eritrea, which effectively ended the twenty-year conflict. The two countries formally ended the conflict at the 2018 Eritrea–Ethiopia summit on 9 July 2018, by signing a joint agreement to resume peaceful diplomatic relations.
