It was after the return of Pacheco, and probably owing to that brave man's advice, that King Emmanuel in 1505 inaugurated a new departure in the relations between Portugal and the East. Pacheco's victories made it evident that it was not only possible for Portuguese garrisons and local squadrons to defend the Portuguese factors, but that they could defeat and conquer powerful native monarchs. A conception of the ease by which a Portuguese empire could be established in the East was now grasped by King Emmanuel. His ideas were still mainly commercial, but he began to perceive also that the safe maintenance of trade and commerce would necessarily involve a regular war to the death with the Muhammadan powers who had reaped the greatest profit from the trade of the East with Europe. Hitherto the Portuguese in India had striven with the Muhammadan Moplas settled on the Malabar coast; but it now became apparent that the Muhammadans of Egypt, Persia, and Arabia would come to the help of their co-religionists. Emmanuel decided therefore to maintain a more powerful army and navy in Asia than he had yet despatched to the Eastern seas, and to replace annual expeditions by a local establishment. Such a force had to be commanded by an experienced general, who should also be a man of rank, in order to exercise undisputed sway over the whole {34} resources of Portugal in the East. For this important office the king first selected Tristão da Cunha, a daring and skilful commander and navigator. But Tristão da Cunha was struck with temporary blindness, and King Emmanuel then chose Dom Francisco de Almeida, a member of one of the most illustrious families of Portugal. Almeida when he sailed received only the title of Chief Captain, but on his arrival at Cannanore on September 12, 1505, he took the high-sounding title of Viceroy of Cochin, Cannanore, and Quilon. The great Portuguese nobleman looked upon the situation of affairs in a different light to his predecessors. He was not satisfied with the idea of protecting the Portuguese trade which had been established, but considered it his duty to destroy the Muhammadan traders and to secure for his countrymen the entire command of the Eastern seas. Since it was necessary for the Portuguese fleets to have some safe ports at which they could refit before and after crossing the Indian Ocean, he built a strong fortress at Quiloa (Kilwa), about 200 miles south of Zanzibar, and made the Chief of Mombassa between Zanzibar and Melinda tributary. He also organised, for the first time, a regular Portuguese Indian pilot service, for he felt it to be a weakness to the Portuguese to be dependent on native pilots like the men who had shown Vasco da Gama the way across the Indian Ocean.
