The war between Eritrea and Ethiopia, which began in May 1998, took the world by surprise. During the war, both sides mobilized huge forces along their common borders and spent several hundred million dollars on military equipment. Outside observers found it difficult to evaluate the highly polarized official statements and proclamations issued by the two governments in conflict.

Brothers at War presents important, contextual aspects to explain the growing discord between the two formerly friendly governments. It looks at the historical relations between the two countries since the late nineteenth century, the historical border issues from local perspectives, and the complicated relations between the former liberation fronts that subsequently formed the current governments of the two countries.
