In historical writings on the Sidama there is certain confusion on who the Sidama were and which areas should be defined as theirs. This group was called the Sidamo cluster in early writings, and the name "Sidamo" was used as a collective for all Cushitic and Omotic people of southwest
Ethiopia. Historian
Lapiso Gedelebo states that the term Sidama was traditionally a demeaning designation used to refer to non
Oromo people by the Oromo. The Sidama people were thought to have originally lived in the historical province of
Bale around the
Dawa River before being driven out by the
Oromos in the early 16th century. The Sidama then led an exodus westwards towards their modern homeland around
Lake Hawassa. According to oral traditions, the Sidama settlers had found the area to be inhabited by another tribe named the
Hofa, but later drove them out. Throughout Sidama history two groups of clans competed for political power. The first group is the
Yemericho which includes eight clans who were the first settlers of the area. They have occupied large contiguous segments of land and have therefore been considered to have the highest degree of purity (agna). The second group is the
Aletta which includes twelve clans who together make up the numerical majority. Clans in Sidama had their own territories and leaders who constantly waged war on each other. The Sidama were then forcefully incorporated into the
Ethiopian Empire during the
Agar Maqnat. Most of the Sidama clans submitted to
Menelik II without a fight. The clans of Hollo-Garbicho and Sawola in the north and some of the Aletta clans in the south had made attempts to defend their territory, but the lack of trust between them and other clans prevented them from coordinating their resistance and forming a united front. Other clans like the Yanase immediately decided to submit to the Emperor and agreed to pay tribute. ==Demographics==
