British historian Michael Wood captures the bravery, endurance, greed, cruelty and suffering involved in these 16th-century explorations. Wood turns his attention to the Americas to follow four amazing tales: Cortes' dramatic conquest of the Aztecs in Mexico; Pizarro's daring overthrow of the Incas in Peru; Orellana's obsessive search for El Dorado and discovery of the Amazon; and Cabeza de Vaca's pivotal crossing of the North American continent.
