What was a purpose of Henry Morgan Stanley's travels in was not a major cause of imperialism in the 1800s?

Henry Morgan Stanley's travels primarily aimed to explore and map uncharted regions of Africa, as well as to locate the missing missionary David Livingstone. While his expeditions contributed to Western knowledge of Africa, they were not a major cause of Imperialism in the 1800s. Instead, the era's imperialism was largely driven by economic motives, competition among European powers, and the desire for new markets and resources, rather than exploration alone. Stanley's work did, however, indirectly support imperial ambitions by legitimizing European claims to African territories.
