Tekle Haymanot was proclaimed Emperor from February 1788 to 1789 by the Emperor Baede Maryam's courtiers.
He established his palace in Gondar, and ruled there for around a year.
[1] He may be identical with the Emperor "Haimanot" mentioned by Henry Salt, who ruled for a year between Iyasu III and Hezqeyas and had died before 1810.
[2] Tekle Haymanot of Gondar is sometimes given the title Atse, a less familiar Amharic word for "Emperor", to distinguish him from the other Emperors of Ethiopia with the same name.
Since he was not recognized as a legitimate ruler, he is not assigned a number.
