According to the map above, in what region were most European coastal settlements concentrated?

I have attached the relevant image below.

Explanation:

The image is a map of Africa, with the most relevant European settlements at the time.

As can be seen, all of them were located in subsharan Africa, because the Mediterranean coast of Africa was a region that had developed from ancient times, and that was in the control of the Ottoman Empire.

The European coastal settlements mostly cluster in west Africa, where the majority of slave ports (ports where slave were taken to the Americas) were located.

There are also some settlements in East Africa, and two settlements to the south of the Gold Coast: Luanda, an important slave port under Portugese control, and Cape Town, initially a Dutch colony.

the answer is solomon northrup. he was a free-born african american, abolitionist and professional violinist that was drugged, kidnapped and sold as slave in 1841 and remained in captivity until 1853 where he regained his freedom with the of the then-governor of new york, washington hunt. he wrote and published his memoirs "twelve years a slave" in 1853, and in this text, he tells the story of his escape thru one of louisiana's swamps (the great pacoudrie swamp) in which he ended up covered in green slime from crossing the surface of the dead water.
