However, the two missionaries, who had become just as much explorers as they were missionaries, became quite interested in Kilimanjaro, and Krapf sought permission of the Mombasa governor for an expedition to the land of the Jagga, a people now known as the Chaga, who lived and live on the actual slopes of Kilimanjaro. Krapf told the governor that this journey would be work-based. Despite this, Krapf actually did not accompany Rebmann on the journey, so only Bwana Kheri and Rebmann left for Kilimanjaro on April 27, 1848.
