1998

Eritrea and Ethiopia went to war over the disputed border town of Badme; two years of fighting killed an estimated 70,000–100,000 soldiers across both sides.

2000

The Algiers Agreement ended major hostilities, establishing a UN-backed Eritrea-Ethiopia Boundary Commission (EEBC) to demarcate the border.

2002

The EEBC awarded Badme to Eritrea, but Ethiopia refused to withdraw; Eritrea suspended diplomatic cooperation and the border hardened into a frozen standoff.

2018

Ethiopian Prime Minister Abiy Ahmed accepted the EEBC ruling and signed a joint peace declaration with Eritrean President Isaias Afwerki, winning Abiy the Nobel Peace Prize.

2020

When civil war erupted in Ethiopia's Tigray region, Eritrean forces crossed the border and fought alongside the Ethiopian federal army against the Tigray People's Liberation Front, committing documented atrocities.

2022

A ceasefire ended the Tigray war but Eritrean troops remained inside Ethiopian territory; Eritrea received no formal concessions, leaving the bilateral relationship tense and unresolved.

2023

Eritrea began backing anti-Abiy armed factions in Ethiopia's Amhara region, resuming its role as a regional destabilizer and signaling the 2018 rapprochement had effectively collapsed.
