With ships and seamen no better than those of any other country in Europe, why did the Portuguese succeed where their Mediterranean predecessors had failed? How did the unique combination of crusading zeal, desire for Guinea gold, the quest for Prestor John, and the search for spices combine to spell success? Here for the first time is a brief comprehensive survey that answers those questions. The book draws on remote royal ordinances revealing much about Portuguese human relations with Indians, Africans, and Brazlians.
