The relations of Portugal with Asia were in their origin, and throughout the reign of King Emmanuel, based on the desire to monopolise the commerce of the East with Europe. The idea of the universal conversion of the heathen to Christianity did not develop itself until the reign of King John III, Emmanuel's eldest son and successor. The idea of empire preceded that of proselytism, and was first enunciated by Albuquerque. The three conceptions are all closely united in the later history of the Portuguese in India, but they were evolved separately, had separate origins and distinct aims. The establishment of direct commerce after the voyage of Vasco da Gama, led inevitably to the imperial notions of Albuquerque. The history of the Dutch and English power in the East followed the same lines, and the parallels which can be drawn are numerous and striking. But the idea of universal conversion to Christianity was a purely Portuguese and sixteenth-century idea. The Dutch and the {146} English East India Companies discouraged Christian missionaries; the Portuguese, on the other hand, in the later days of their ascendancy, made their whole system of government subservient to the propagation of the Christian faith. It is not necessary here to draw deductions from this striking contrast. It is purely a matter of speculation whether this difference was due to religious causes or to the idiosyncrasies of the different nations; but the fact remains, and gives a peculiar interest to the history of the Portuguese in the East, as connected with the history of the extension of Christianity. The voyage of Vasco da Gama, as well as the explorations of Prince Henry the Navigator, was dictated by commercial causes alone. Incidentally the Portuguese were interested in the discovery of native Christians on the Malabar coast and of a Christian Empire in Abyssinia. But it cannot be too strongly insisted upon that the primary aim of the Portuguese was commercial and not religious. The idea of empire was forced on the Portuguese by the opposition they met with in the establishment of their commerce. Vasco da Gama had no idea of conquering the cities he touched at on the Malabar coast; he merely wished to open up trade relations. Cabral, who followed him, gave evidence of his peaceful intentions by sending the first Portuguese factor, Correa, ashore at Calicut with only a few clerks. But the murder of Correa and the subsequent attacks on the Portuguese factories at Cochin {147} and Quilon showed that peaceful trade could not possibly be established in the then condition of the Malabar coast. It was necessary to supplement factories by fortresses, and it is significant that the first fortress built was founded by Albuquerque during his first voyage to India.
