Negus Mikael of Wollo (born Mohammed Ali, 1850 – 8 September 1918), was an army commander and a member of the nobility of the Ethiopian Empire.

Mohammed Ali's lineage included both Oromo and Amharic speaking ancestors attesting to the multiethnic populace of Wollo.

[2] In the infamous "Council of Boru Meda," Emperor Yohannes forced Mohammed Ali and the Muslim aristocrats of Wollo to convert to Christianity within three months or renounce their positions.

"Having concluded that Wollo was worth a mass," Marcus claims, "Mohammad Ali led his people to Christianity."

In Ifat province rebel leader Talha Jafar led an insurgency in 1879 which defeated Mikael's forces.

It is claimed that Ras Mikael became a deeply devout Ethiopian Orthodox Christian, and a dedicated builder of churches.

[citation needed] In 1896, during the First Italo-Ethiopian War, Ras Mikael fought with Menelik and led the feared Wollo cavalry against the invading Italians at the Battle of Adwa.

[6] During World War I, concerns arose over Iyasu's ties to the Central Powers, over his possible support for Mohammed Abdullah Hassan, and over his potential conversion to Islam.

On 27 October, Negus Mikael confronted the main body of the forces supporting Zewditu in the Battle of Segale.

[8] Mikael was captured and put under the supervision of Fitawrari ("Commander of the Vanguard") Habte Giyorgis, who confined him on an island in Lake Chabo in Gurageland.

After two and a half years, Mikael successfully petitioned to Empress Zewditu to be moved from the island, and he was put under house arrest at Holeta Genet at a former country home of the late Emperor Menelik II, where he died six months later.
