Origins & Early Life

The Battle of Diu was a naval battle fought on 3 February 1509 in the Arabian Sea, in the port of Diu, India, between the Portuguese Empire and a joint fleet of the Sultan of Gujarat, the Mamlûk Burji Sultanate of Egypt and the Zamorin of Calicut. The Portuguese victory was critical: the great Muslim alliance was soundly defeated, easing the Portuguese strategy of controlling the Indian Ocean to route trade down the Cape of Good Hope, circumventing the historical spice trade controlled by the Arabs and the Venetians through the Red Sea and Persian Gulf. After the battle, the Portugal rapidly captured several key ports in the Indian Ocean including Goa, Malacca, and Ormuz. The territorial losses crippled the Mamluk Sultanate and the Gujarat Sultanate. The battle catapulted the growth of the Portuguese Empire and established its political dominance for more than a century.

Career & Major Achievements

The Battle of Diu marked the superiority of Portuguese shipbuilding, artillery and naval tactics over local resources. It was a battle of annihilation similar to the Battle of Lepanto and the Battle of Trafalgar, and one of the most important in world naval history, for it marks the beginning of European dominance over Asian seas that would last until the Second World War. Just two years after Vasco da Gama reached India by sea, the Portuguese realized that the prospect of developing trade such as that which they had practiced in West Africa had become an impossibility, due to the opposition of Muslim merchant elites in the western coast of India, who incited attacks against Portuguese feitorias, ships, and agents; sabotaged Portuguese diplomatic efforts; and led the massacre of the Portuguese in Calicut in 1500. Thus, the Portuguese signed an alliance with a sworn enemy of Calicut instead, the Raja of Cochin, who invited them to establish headquarters. The Zamorin of Calicut invaded Cochin in response, but the Portuguese were able to devastate the lands and cripple the trade of Calicut, then the main exporter of spices back to Europe, through the Red Sea.

Enduring Legacy & Impact

In December 1504, the Portuguese destroyed the Zamorin's yearly merchant fleet, bound for Egypt and laden with spices. When King Manuel I of Portugal received news of these developments, he decided to nominate Dom Francisco de Almeida as the first viceroy of India with expressed orders not just limited to safeguarding Portuguese feitorias, but also to curb hostile Muslim shipping. Dom Francisco departed from Lisbon in March 1505 with twenty ships and his 20-year-old son, Dom Lourenço, who was himself nominated capitão-mor do mar da Índia or captain-major of the sea of India. Portuguese intervention was seriously disrupting Muslim trade in the Indian Ocean, threatening Venetian interests as well, as the Portuguese became able to undersell the Venetians in the spice trade in Europe. Unable to oppose the Portuguese, the Muslim communities of traders in India as well as the sovereign of Calicut, the Zamorin, sent envoys to Egypt pleading for aid against the Portuguese.
