Cause

After Eritrea gained independence from Ethiopia in 1993, initial cordial relations gave way to serious disagreements over the demarcation of their shared border. The town of Badme became the focal point of territorial dispute, and diplomatic tensions escalated until both nations mobilized for war in 1998.

Event

From May 6, 1998 to June 18, 2000, Ethiopia and Eritrea fought a large-scale conventional war along their disputed border, deploying over 500,000 troops combined. The fighting involved extensive trench warfare and aerial combat, resulting in between 70,000 and 300,000 deaths and the displacement of approximately 600,000 people.

Consequence

The war ended formally with the Algiers Agreement on December 12, 2000. A boundary commission concluded in 2005 that Badme belonged to Eritrea, though border tensions persisted for nearly two decades. Full peace was only declared in July 2018 after Ethiopian Prime Minister Abiy Ahmed agreed to implement the treaty, a move that contributed to his Nobel Peace Prize.
