* Combating Slavery: He became known for his opposition to the Arab slave trade and advocated for the rights of Africans.
* Promoting Christianity: As a missionary, he established mission stations and aimed to spread Christianity in the region.
* Opening Africa to Trade: While not his primary goal, his explorations and discoveries helped open up Africa to European trade and colonial influence.
His explorations and work helped shed light on the African continent for the rest of the world. However, it is important to note that his work was also part of the larger colonialist narrative, and his presence had both positive and negative impacts on the African people.
