The correct answer to this open question is the following.
What caused West Africans to transition from controlling the exchange of goods to European slave raiders was the fact that European powers such as Great Britain, Spain, or Portugal directly competed to acquire the control of the slave trade of African people.
Everything started with John Hawkins, considered to be the first European slave trader in 1562. Years later the government of Englan granted charters to merchants and traders to open locations in West Africa where they could exploit the raw materials and natural resources such as ivory and gold. Because of this, England started to get more competition from other European nations such as Switzerland, the Dutch, and Denmark.
There are three main ways African religions communicate with the supernatural. Brief description to each is found below.
Supreme God
They worshipped the Supreme God through constant communion with lesser deities and ancestral spirits. This is done by performing libation or sacrifice — offering animals, vegetables, food, flowers and other precious materials.
Divination
This is the term given when consulting to oracular deities. There are a lot of techniques on casting divination, but actual practice is done with small objects e.g. bones, shells, stones, leathers or wood pieces.
Cyclical nature of reality
Believing that nature is an integral part of their religion. So, all natural phenomena is thought to be responsible for their daily needs. This encloses aspects such as tides, moon, rain, day, sun, stars, etc.
