<u>Ethiopia defeat Portugal to stay independent:</u>
The Abyssinian-Adal(Ethiopia & Portugal) War was a military conflict between the "Ethiopian Empire and the Adal Sultanate" that took place from 1529 to 1543. The Abyssinian troops included the Amhara, Tigrayan, and Aegay ethnic groups. The Adal army consisted mostly of Afar, Harari, Somali with Argoba forces.
In the process both politicians exhausted their resources and manpower, resulting in a contraction of both powers and changing "regional dynamics for centuries" to come. In 1529, Imam Ahmad's contingents defeated a large amount of Ethiopian contingent at the "Battle of Shimba Qir". The victory came at a huge cost, but it strengthened the morale of the Somali army, providing evidence that they could stand with the Ethiopian army at large.
