The singer and activist was a member of Ethiopia’s largest ethnic group, the Oromo, who have long been marginalized despite their numbers. His songs of resistance made him a hero to a generation of young people struggling for political and economic change.
After his death, violent protests broke out in Addis Ababa and the neighboring Oromia region. Officials said that at least 239 people had been killed in the unrest, during which buildings were burned and groups of young men carried out ethnically motivated attacks.
The government blocked the internet and arrested nearly 5,000 people, including activists, journalists and a prominent critic of the government, Jawar Mohammed. Tensions also escalated when the police blocked mourners from attending Mr. Hundessa’s funeral in his hometown, Ambo, 60 miles west of the capital.
The violence has posed a challenge to Prime Minister Abiy Ahmed, who is overseeing Ethiopia’s delicate transition from authoritarian rule to multiparty democracy.
Mr. Hundessa’s music provided a soundtrack to a wave of antigovernment protests that began in 2015, which eventually led to the resignation of the prime minister at the time, Hailemariam Desalegn, and the rise of Mr. Abiy, an Oromo himself.
