Cause → Event → Consequence
The Portuguese sought to control Indian Ocean trade by diverting the lucrative spice trade away from Arab and Venetian merchants who routed goods through the Red Sea and Persian Gulf. A coalition of Muslim powers — the Sultan of Gujarat, the Mamluk Sultanate of Egypt, and the Zamorin of Calicut — united to resist Portuguese expansion into their commercial sphere.
On 3 February 1509, a Portuguese fleet engaged the combined Muslim coalition fleet in the Arabian Sea off the port of Diu, India. Superior Portuguese shipbuilding, artillery, and naval tactics proved decisive; the allied fleet was annihilated in what historians rank among the most consequential naval engagements in world history.
The Portuguese victory dismantled Arab control of Indian Ocean commerce and enabled rapid Portuguese seizure of key ports including Goa, Malacca, and Ormuz. The Mamluk and Gujarat sultanates suffered crippling territorial losses. Portugal established political dominance over Asian seas that endured for more than a century, inaugurating an era of European maritime supremacy that lasted until the Second World War.
