The Nile
Looking for the source of the Nile, many explorores had varying opinions of just where that would lead them to. It became a very hot topic among the science community and still isn't solved today. Many explorores followed the primary river also called the white Nile and still found nothing.
Western coast of sub sahara Africa and Zanzibar
With Britain having control of South Africa and the many trade opportunities that it provided, such as wine and military positioning they began working to expand outward for better trade and land. Many explorers 'discovered' more of the west coast of Africa as a way to avoid the thriving African and Arab slave trade occurring on the east coast. Even so, they relied heavily on slavers and slave labor as they interacted with the Zanzibar people.
The hunt for the source of the Nile
Before the major colonization of Africa by Europe, the first few English adventures were sent to map terrain, collect samples and specimens, and steal--or gather artifacts for scientific societies, museums, and other sponsoring agencies. Upon some great and exciting success, the church begins sending missionaries and using their stories in services and disseminating religious periodicals.
