According to Beckingham and Huntingford, there is evidence that the monarchy of Gera existed before the
Great Oromo migration in the 16th century. However, according to Mohammed Hassen, Gera was the last of the Gibe kingdoms to come into existence, and was founded by Gunji, "a successful war leader who made himself king" around 1835, but died shortly afterwards. This dynasty came to an end with the murder of
Tulu Ganje by king
Oncho of Gumma. A new one was founded by
Abba Baso, who proved to be an unpopular ruler. He was later overthrown by his brother
Abba Rago and exiled to
Jimma. According to Trimingham, the kingdom enjoyed its greatest prosperity under king
Abba Magal, who had been converted to
Islam, although a number of his subjects still professed
Christianity. It unclear which Gibe king was responsible for this conversion: Trimingham attributes this achievement to
Abba Jubir of Gumma; Mohammed Hassen gives the initial credit to
Abba Bagibo of
Limmu-Ennarea, who offered to support Abba Magal in his fight for the throne if he allowed Muslim missionaries into his kingdom, and only later did Abba Jubir convert him. On King Abba Magal's death, his wife
Genne Fa acted as regent for their son, both of whom became prisoners in Jimma when Gera was conquered by
Dejazmach Besha Abua in 1887. ==See also==
