On November 2, representatives of the Ethiopian federal government and the Tigray People’s Liberation Front (TPLF) agreed to a cessation of hostilities after peace talks led by the African Union in South Africa.
That agreement, on the eve of the second anniversary of the war, brought an end to a conflict that began after Nobel Peace Prize-winning Prime Minister Abiy Ahmed sent troops into the northern region of Tigray in November 2020.
Both sides are currently in the process of implementing the points agreed to in the peace agreement.
The conflict left thousands dead and displaced millions in Tigray but now there is hope that humanitarian aid can start flowing back into the region where more than 90 percent of its 5.4 million people urgently require food aid, according to the United Nations.
Here is a timeline of the two-year war.
November 4, 2020: Prime Minister Abiy orders troops to respond to an attack on federal army camps that he blamed on the TPLF, which denied this. The fighting was an outcome of months-long tensions between the sides. In September 2020, Tigray had held regional elections in defiance of Addis Ababa which postponed the polls until August due to COVID-19. As a result, the federal government called the vote illegal and started withholding social welfare funds from Tigray.
November 9: The war intensifies as at least 600 civilians are killed in a massacre in the town of Mai Kadra. With telephone and internet communication lines cut, information was hard to obtain and verify. Abiy says the operation will be over “soon” as the fighting escalates with thousands of people killed so far and tens of thousands displaced.
November 14: The TPLF fires rockets into Asmara, the capital of neighbouring Eritrea that has been supporting the federal government. TPLF leader Debretsion Gebremichael also says his forces have been fighting Eritrean troops “on several fronts” in the days before.
The 10-day conflict leads to tens of thousands of refugees fleeing into neighbouring Sudan, describing the horror of intense fighting, including horrific killings. The United Nations warns of possible war crimes in Tigray.
The relations between Ethiopia and Sudan are on edge with the incoming refugees as longstanding territorial claims between both sides are deadlocked.
November 28: Abiy announces that military operations in Tigray have been “completed”. However, fighting continues in parts of Tigray.
January 27, 2021: The US calls on Eritrea to “immediately” withdraw its troops who have been fighting in Tigray. But Ethiopia’s government denies their presence in the country.

The next day, the Ethiopian Human Rights Commission (EHRC) says Eritrean soldiers massacred more than 100 civilians in Axum in November. The findings by the government-affiliated but independent body corroborate separate investigations by Amnesty and Human Rights Watch.
