Объяснение:
Изучение Африки европейцами — изучение Африки европейскими путешественниками. Знакомство европейцев с Африкой началось ещё в античности. Античные путешественники изучали Северную Африку; при этом собственно Африкой или Ливией считали континент за пределами Египта, который считался частью Азии. Исследования Африки южнее Сахары активно продолжились в эпоху географических открытий (начиная с XV в.). Основную роль играли португальские мореплаватели: так, Бартоломео Диас в 1488 году достиг Мыса Доброй Надежды, открыв морской путь в Индию и на Дальний восток. При этом знакомство с внутренней частью континента в XVI, XVII и первой половине XVIII вв. оставалось незначительным: основную роль в нём играли работорговцы. В начале XIX в. сведения европейцев об Африке южнее Сахары оставались незначительными. Исследования Южной Африки активно продолжались в 1830-1840 годах, и активно развивались во второй половине XIX вв. во время колониального дележа континента. Большую роль в этом процессе играли поиски истоков Нила.
