Ethiopia-Eritrea War (1998-2000)
A border dispute over the town of Badme escalated into a two-year war that killed tens of thousands and displaced roughly half a million people. Both countries mobilized mass armies along a heavily fortified front.
The Algiers Agreement and UN border ruling ended the war butsatisfied neither side, leaving a frozen conflict that lasted two decades.
Relations stayed frozen until the 2018 peace pact between Abiy Ahmed and Isaias Afwerki, which collapsed amid renewed tensions in the early 2020s.
Ethiopia breaking diplomatic ties with Eritrea now echoes the frozen relationship that preceded the 1998 war.
