Explanation:
<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.
500 Muscatiers were led by the Bahri Negassi Yeshak, the king of Medri Bahri. Not only did Yasakh provide the Portuguese with provisions and places to camp within their scope, but also informed them about the land.
That depends on what you consider to be resistance. Most of them stopped during the 19th century after numerous acts and policies that were widely accepted since everyone wanted to avoid bloodshed. Some would argue that it lasted until the 1920s, when the final acts of attacks were held in countries such as Utah, but this was on a really small scale.
