How did Sebastien Muenster's work impact the African continent? He worked as a middleman in the slave trade, brokering deals with other European nations for slaves.

His ideas reduced the dangers of sleeping sickness by moving settlements farther away from regions where flies were prevalent.

His maps of the entire continent encouraged other nations to send explorers to find goods, gold, and land.

His explorations spread French culture through the colonies of Mauritania, Senegal, French Sudan (now Mali), French Guinea, Ivory Coast, and Niger.
