"The Oromo view their original homeland as the southern highlands of present-day Ethiopia. It is known that between the 12th and 15th centuries, they were already organized into two confederations known as the Barentu and Borana federations. It was during this period that Oromos began their expansion from their homeland area in all directions. Today, all Oromo subgroup trace their heritage to one of these federations. Rather than being a pure ethnic group, the Oromo are comprised of descendants of individuals who, even when they were not of pure Oromo stock, willingly accepted or were forced to accept an Oromo identity. Jalata notes that the Oromo historically increased their numbers through the assimilation of other peoples they conquered.
The assimilation process was facilitated by the institution of a unique administrative system among the Oromo known as gada."
