Ethiopia is Africa's oldest independent country and its second largest in terms of population. Apart from a five-year occupation by Mussolini's Italy, it has never been colonised.
It has a unique cultural heritage, being the home of the Ethiopian Orthodox Church - one of the oldest Christian denominations - and a monarchy that ended only in the coup of 1974.
It served as a symbol of African independence throughout the continent's colonial period, and was a founder member of the United Nations and the African base for many international organisations.
Drought and civil conflict left Ethiopia in a state of turmoil under a Marxist dictatorship from the fall of the monarchy until 1991, when the long authoritarian rule of Meles Zenawi brought a degree of stability.
Prime Minister Abiy Ahmed launched a campaign of political liberalisation at home, and sought to end disputes with Ethiopia's neighbours, in particular Eritrea, after 2018.
But these efforts were overshadowed by a dispute with the leaders of Tigray region that began in 2020 and swiftly escalated into armed conflict.
President: Sahle-Work Zewde
Parliament elected Sahle-Work Zewde as the Ethiopia's first woman president in October 2018.
Ms Sahle-Work, an experienced diplomat, promised to work to make gender equality a reality at her swearing-in to the largely ceremonial post.
She took office a week after Prime Minister Abiy Ahmed appointed a cabinet with half the posts taken by women.
Prime minister: Abiy Ahmed
Abiy Ahmed was chosen to lead the ruling Ethiopian People Revolutionary Democratic Front coalition after the unexpected resignation of Prime Minister Hailemariam Desalegn in 2018.
He pledged to try to end longstanding tensions with neighbouring Eritrea, and within months the two countries declared that the state of war between them was over.
Mr Abiy also pledged to bring more transparency to government and reconciliation to a country that had been torn by protests since 2015.
But tensions with Tigray region in 2020 led the federal government to send in troops after an unsanctioned regional election, triggering armed conflict.
The change of government in 2018 ushered in a new era for the media, which for many years had operated in one of the region's most restrictive environments.
But Reporters Without Borders says there have been no significant improvements to harsh media laws.
The state controls most broadcasting outlets, including national broadcasters ETV and Radio Ethiopia.
Internet and mobile services have been restricted during periods of social unrest.
