Betul Haile Maryam[note 1] (1812 – 29 June 1853, Ayshal) was a member of the Semien nobility through his paternal line in the Ethiopian Empire.
His half brother Wube Haile Maryam was one of the most famous protagonist of the Zemene Mesafint era.
Humiliated, Betul and Merso entered into the service of Wube's army and joined his campaigns against the sons of Sabagadis, their former patron.
[1][4] In 1840, Betul and Merso allied with their mother's nephew, the regent Ali II of Yejju, and this was soon followed by a battle with Wube at Debre Tabor in 1842.
[1] On 29 June 1853 a decisive battle took place on the plains of Ayshal, between the forces of Ras Ali against that of Kassa Hailu.
