Question

Where was Oromo First developed

Answer 1

The Oromo originated in southern Ethiopia, together with the Somali, around the tenth Century, and lived in southern Ethiopia and northern Kenya till their migrations began about 1530. In 1537 they entered the south-eastern province of Bali, following campaigns against the Ethiopian kings, 500 miles away from their homeland.
The Oromo trace their places of origin to Boorana in southern Ethiopia, where places such as Dirre and Liban are considered their homelands. However, several expansions took place in the last 300 years, due to their pastoral movements, and their constant interaction with Somali over resources, that not only affected movements in Ethiopia itself, but also in regions of Kenya such as the Tana river, and regions of Somalia such as Juba.
During the 1800s and due to the arrival of Europeans in Ethiopia, migrations assumed a different nature and became more localized. By 1896, the Oromo were by force made subjects of the Abyssinian king Menelik II, after he defeated the Italian army at the battle of Adwa. Therefore, and already by 1904, treatises between Britain and Ethiopia assured the fixity of the borders, and therefore created a self-contained territory where Oromo lived on both sides of the border (Ethiopia/Kenya)
