His Motto Came To Represent The British Empire.
Although there was already a well-established trans-regional network of trade routes, Livingstone rose to fame as the first European to cross south-central Africa at that latitude and was credited with having "opened up" Africa. Portuguese traders had traversed the continent from both sides to the middle; in 1853–1854, two Arab traders traveled from Zanzibar to Benguela; and in the early 1800s, two native traders traveled from Angola to Mozambique. However, Livingstone's main objective was to end the African slave trade, which was practiced by the Portuguese of Tete and the Arab Swahili of Kilwa.
When Livingstone made three lengthy voyages across Africa, he aimed to spread Christianity, commerce, and "civilization" there. His statue, which is located near to Victoria Falls, is inscribed with this saying, which he upheld throughout his whole missionary career. He hoped that this combination would create an alternative to the slave trade and give Africans respect in the eyes of Europeans. He thought that using the Zambezi River as a Christian trade route into the interior was the key to achieving his objectives. The phrase was adopted as a slogan by British Empire administrators to support the growth of their colonial domain. It came to represent neo-Darwinist notions of the "White Man's Burden," which held that it was the duty of European nations to spread civilization throughout the rest of the globe. Because of this, colonial aspirations were seen as an "obligation" for European powers. That's all about the seventh fact about David Livingstone.
