What factors shaped each of the main reasons of africa during the early 1800's?

From research I found this to be the best and closest of all answers: "North Africa, West Africa, East Africa, and the Zulus power were all apart of the factors that shaped Africa during the early 1800s. These factors were also known as improvement for each part of Africa. These improvements are as listed > North Africa was under the rule of declining the Ottoman Empire. They were trying to expand, I suppose. West Africa experienced an Islamic revival. This was mainly the education of the Islamic culture if I'm not mistaken. This was known as "Western Science." East Africa's port cities, making for profitable trade. This was an attraction because of the amounts of gold that was coming in. Zulus, being a major force at the time, it was also a language.  "Zulu" meaning "Sky."
