Document 2: Universities' Mission to Central Africa: To advance these goals, it sought to send a mission led by a bishop into Central Africa; Charles Mackenzie was duly consecrated in 1860 and led an expedition in 1861 up the Zambezi into the Shire Highlands. This first expedition was more or less disastrous. The area chosen as a base, near Lake Nyasa (Lake Malawi), proved highly malarial; Bishop Mackenzie died there of the disease on 31 January 1862, along with many local people and three others among the tiny missionary party. Early conversion efforts from this base yielded little result, and supplies ran out or were destroyed during a period of famine. The mission then withdrew from the area, abandoning the graves of the missionaries who had died there, and though it established a new presence in Zanzibar many years passed before it returned to Malawi. Bishop Tozer, Mackenzie's successor, deemed the mission's early years ``a miserable failure ''.

Document 5: Legend of the Lost: Wayne liked the location work in Rome and Libya. The plot is vaguely similar to another of Wayne's movies crossing the Mojave Desert. The Roman remains of Leptis Magna in Libya were used extensively as a location for the ancient city. In the script Wayne's character refers to 'Timgad' in sardonic reference to the apparent delusions of Paul's father, despite the fact this places a considerable strain on the geography of the plot. The lost city of Timgad referred to in the film was actually the Leptis Magna ruins, a Roman city dating back to the 7th century B.C. near Tripoli, in northwest Libya, while ``Timbuktu ''was actually in Zliten, Libya. Headquarters for the film were located in Ghadames, where, according to the publicity material, citizens of the villages were employed on set, as well as some native Tuaregs, an ancient desert tribe.

Commercial relationships quickly grew between the inland Bantu kingdoms and European merchants who traded various commodities, manufactured goods, and people captured from the hinterlands.

The mosaics show a warrior in combat with a deer, four young men wrestling a wild bull to the ground, and a gladiator resting in a state of fatigue, staring at his slain opponent.

Document 15: European exploration of Africa: European exploration of Sub-Saharan Africa begins with the Age of Discovery in the 15th century, pioneered by Portugal under Henry the Navigator. The Cape of Good Hope was first reached by Bartolomeu Dias on 12 March 1488, opening the important sea route to India and the Far East, but European exploration of Africa itself remained very limited during the 16th and 17th centuries. The European powers were content to establish trading posts along the coast while they were actively exploring and colonizing the New World. Exploration of the interior of Africa was thus mostly left to the Arab slave traders, who in tandem with the Muslim conquest of the Sudan established far - reaching networks and supported the economy of a number of Sahelian kingdoms during the 15th to 18th centuries.
