Oromo Population Movement in 16th Century Africa

Oromo Population Movement and Expansion

• In the 16th century, war and population movements dominated the history of the Horn of Africa.
• The Afar and Somali population movements began earlier than that of the Oromo.
• Drought, famine, and land pressure led to conflict among Argobba, Harari, Afars, and Somalis in South East Ethiopia.
• Imam Ahmed of Adal united the Afars and Somalis, leading to the occupation of territories and attack on the Christian kingdom in the 1st half of the 16th century.
• The Oromo population movement was caused by human and demographic factors, including war and disturbances in the 15th and early 16th centuries.

Original Homeland of the Oromo

• The Oromo's original homeland is disputed, with some believing it to be the southeast part of Ethiopia highlands, south-central part of Ethiopia highland, or east of the Rift Valley Lake.
• Evidences suggest that the Oromo originated from the north and moved southeastwards due to the expansion of Christians and Muslims.
• The Oromo are indigenous to Ethiopia and the Horn.

Oromo Institution and Social Organization

• The Oromo had their own political, social, and religious institution before and during their movement.
• The Oromo were organized into the Gada system for political, economic, and social purposes.
• The Gada system dates back to nearly 9,000 years ago and served as the constitution of the Oromo, administering, defending their territory, and developing their economy.
• The Gada calendar consists of 8-year periods, with 5 Gada periods representing one generation.
• The Gada Grades are the grades Oromo males passed through from birth to death, with each grade lasting 8 years.
• The sixth age-grade (41-48 years) is called Gada, where Oromo males take on political, social, military, and ritual leadership.
• The Gada class, also known as Gada parties, consist of five parties that succeed each other every 8 years in providing military, social, and ritual leadership.
